StarSpan ChangeLog
$Id: ChangeLog,v 1.86 2008-07-26 21:57:19 crueda Exp $
2011-09-06 (1.2.06) mperry
- set table_suffix default to NULL;
- make full table output in --outtype=table mode optional
2011-08-17 (1.2.05) mperry
- We (Ecotrust) have forked starspan and are providing this patched version since the original, developed at UC Davis, is no longer maintained.
- Specifically, this version can be compiled with a newer version of GCC (e.g. GCC 4.4 which ships with Ubuntu 10.4) by explicitly including standard libs.
- This version of starspan is also updated to play nice with GEOS 3.3 which requires dynamic_casts (rather than the C-style casts used in the original code).
2008-07-24 (1.2.03)
- Fix of bug [200376] Projections do not match under GDAL 1.4:
Flag --validate_inputs added.
By default, starspan will not prevalidate the various input elements for
consistent projection info. This flag enables this check.
(Environment variable STARSPAN_NO_VALIDATE_INPUTS no longer used).
MinGW build successful using 1.5.2.
See http://starspan.casil.ucdavis.edu/doku/doku.php?id=mingw
- New binaries/windows/mingw_prepare_binaries.sh to facilitate preparation
of windows release.
2008-07-19
- some fixes with new naming mechanism with suffixes.
- Using new version of GuiE that fully shows the output of
`sys-commands` in text components.
2008-07-18
- Various adjustments to create Windows releases.
2008-07-08 (1.2.01) alpha release.
2008-07-07 (starting versions 1.2.xx)
NOTE: Several changes in command line interface.
- Removed old stuff that hasn't been tested for a long time.
The following options have been removed:
--raster_directory <directory>
--update-csv <filename>
--envi <name>
--envisl <name>
--speclib <filename>
--calbase <link> <filename> [<stats>...]
Renamed options:
--duplicate_pixel -> --duplicate
--report_elapsed_time -> --elapsed_time
Added options according to new command line interface, some of which
replace corresponding pre-existing options in the old style:
--out-prefix <string> --out-type <type>
--table-suffix <string>
--summary-suffix <string> --stats <stat> <stat>
--class-summary-suffix <string>
--mr-img-suffix <string> --mini_raster_parity <parity>
--mrst-img-suffix <string> --mrst-shp-suffix <string>
--mrst-fid-suffix <string> --mrst-glt-suffix <string>
Also the GuiE spec gui/base_dist/bin/starspan.guie has been updated
accordingly. (BTW, now using GuiE 0.2.8)
2008-05-15
- Implemented ignore_nodata mode to select from multiple rasters
--duplicate_pixel ignore_nodata {all_bands | any_band | band <#>}
Any pixel in the feature being processed that satisfies the condition
according to the mode will be ignored. The conditions are:
all_bands: all bands with the nodata value
any_band: any band with the nodata value
band <#>: especific band number # with the nodata value
- BoxParams: width and height now allow a qualifier; for now, only the "px"
suffix to indicate units in pixels instead of dataset's units.
2008-05-08
- common.h: added def:
#define RID_colName "RID"
TODO: Other similar hard-coded values, but in general with a parameterized
mechanism.
- mini_raster_strip with shapefile creation: --RID option handled; it creates
"RID" (ie, RID_colName) column if RID option != "none" and puts the value
accordingly.
- Simplifying parameter handling for traverser: instead of replicating them
in traverser's own structures/variables, just use the globalOptions structure:
- boxParams: done
- bufferParams: done
- vSelParams: done
- verbose: done
- pixelProportion: done
- skip_invalid_polys: done
2008-05-07 (1.0.08)
- starspan_create_strip(): Explicitly assigning the geoTransform to the
generated strips. It uses the geoTransform from the first miniraster but
sets the origin point to be (0,0).
In particular, for the --mini_raster_strip command with shapefile creation,
this adjustment makes the generated datasets to match properly.
- Since starspan now checks that the projection of the input datasets be
the same, I converted the polygon shapefile for the current tests to
match the projection of the raster files:
cd tests/data/vector
ogr2ogr -t_srs "+proj=utm +zone=10 +ellps=WGS84 +datum=WGS84 +units=m +no_defs" \
ply/ply.shp starspan_testply.shp
Also converted the other shapefiles for future use.
(cd tests && make) # -> OK
2008-05-01,02
- Refactoring miniraster strip creation to allow duplicate pixel handling:
- MiniRasterObserver: no Traverser as a member any more.
- IntersectionInfo: now includes the traverser.
- MiniRasterStripObserver: setOutVector() and setOutVectorDirectly()
to allow association of output vector either with no ownership or with
ownership.
- MiniRasterStripObserver.create_strip() removed. Instead, this functionality
was moved to new utility starspan_create_strip().
- New starspan_getMiniRasterStripObserver2() and starspan_minirasterstrip2()
to handle the generation of the strip with duplicate_pixel modes.
- TODO: complete preliminary tests.
2008-04-24
- GRASS interface documentation updated in web site:
http://starspan.casil.ucdavis.edu/doku/doku.php?id=grass
- Rasterization process documented in:
http://starspan.casil.ucdavis.edu/doku/doku.php?id=rasterization
--rasterize option still internal for testing purposes.
Also added rasterize command to GRASS interface to facilitate this
testing, although the GDAL GRASS driver cannot create new GRASS rasters;
using ENVI for output rasters for now.
2008-04-22
- Implemented grass interface commands:
report
csv
- Each command is GRASS-configured individually so it is better dispatched
in terms of pertinent options. Also, the command can be dispached from
the GRASS GUI, including selection according to input map: vector or raster.
NOTE: starspan_dup_pixel() was segfaulting with versions geos 2.2.3 and
gdal 1.5.0. Just updated geos to 3.0.0 (on pegasus) and problem fixed.
2008-04-21
- New starspan_grass.cc: preliminaries for providing a GRASS interface.
2008-04-18
- New starspan_rasterize.cc: goal: do some basic comparisons with the
output generated by GRASS' v.to.rast.
2008-04-17
- Code cleanup:
- Removed (not used):
- starspan_csv_dup_pixel.cc
- starspan_db.cc
- starspan_tuct1.cc
- starspan_update_dbf.cc
- function starspan_myErrorHandler()
- Improved comments to some sources
- Moved src/rasterizers/agg_*.h to new dir src/rasterizers/agg/
(agg is used only for line rasterization but other types of
rasterization may eventually be located in src/rasterizers/.)
2008-04-11
- new IntersectionInfo struct to add more information in intersectionFound()
and intersectionEnd() traversal observer interface.
- Shapefile creation for mini_raster_strip now working including for --box
option. Tested as follows (under tests/):
* Mini raster strip with accompanying shapefile and using the –in option:
../starspan2 \
--vector data/vector/starspan_testply.shp \
--raster data/raster/starspan2raster.img \
--mini_raster_strip generated/mrstrip/myoutput_ \
generated/mrstrip/myoutput.shp \
--in \
--separation 10

- Some code cleanup:
Removed vector/{Makefile,Vector_shapelib.cc}
- Adding shapefile creation for mini_raster_strip
2008-04-05 (1.0.08)
- tests/Makefile: use zcat for comparison instead of gunzip
(so the .gz, which is on CVS, is preserved).
- Removed FR 200347: --mini_raster_box option
- Added FR 200348: extract a centered box wrt feature's bounding box.
This is implemented with the --box option, which behaves as a variant
of the --buffer operation, so it's handled by traverser.
Only one of --buffer or --box may be specified.
- Removed starspan_minirasterstrip.cc (function starspan_miniraster_strip())
Was never implemented.
2008-03-27 (1.0.08)
- Fresh release to facilitate creation of windows binaries.
2008-03-03 (1.0.07)
- Adding options --sql, --where, and --dialect à la ogrinfo.
Preliminary tests OK.
More details about the syntax for --sql: http://gdal.org/ogr/ogr_sql.html
The "where" section corresponds to the --where option.
In starspan you will write something like for example:
starspan --vector myvector.shp \
--where "(SITE_ID >= 10) and (SITE_ID <= 20)" ...other options...
Although more tests are pending, I think these new options should work as
expected.
- removed unneeded starspan_csv_dup_pixel.cc from Makefile.am
- configure.in, starspan.in: using program_prefix and program_suffix to
refer to binary executable, so the corresponding ./configure options
are honored.
- Adjustments to GEOS include files according to deprecated warning
issued by GEOS 3.0.0
- Since GDAL and GRASS are working nicely together on pegasus, I just made a
basic test to confirm that starspan can access vector and raster GRASS
datasets, and everything seems to work fine. For example, according the
the naming of the datasources explained in http://gdal.org/ogr/drv_grass.html
and http://gdal.org/frmt_grass.html:
starspan --raster /proj/delta/gis/grass/delta/lidar_shadows/cellhd/200506_p1_31_beam_irradiance --report
starspan --vector /proj/delta/gis/grass/delta/carueda/vector/starspan_testply/head --report
Note that you don't have to launch these commands from within GRASS to access
the datasets. However, more information is reported for rasters
when the command is launched from within GRASS.
Note also that accepting the inputs according to the GRASS syntax, for example:
starspan-grass raster=00506_p1_31_beam_irradiance@lidar_shadows vector=somevector@somewhere ...etc...
is another story; this would required a concrete module in starspan especially
designed to use the GRASS APIs.
2008-02-05
- Included --gui extended option to launch the GUI
2008-02-02
- starspan_csv_dup_pixel.cc: Minor changes in log messages for
easier inspection.
2008-01-28
- Added processing of rasters according to associated masks.

- TODO: mask handling on other options/commands -- now, only done for the
--duplicate_pixel and --csv commands
2008-01-24 (1.0.06)
- First tests on --duplicate_pixel
- Dev note: layer->ResetReading() call in traverse()
New static flag: bool _resetReading in class Traverser:
By default, traverse() starts by calling ResetReading on the layer
(_resetReading == true).
However, this is in general not appropriate because it precludes the
traversal from being used as a subtask.
For example, in starspan_csv_dup_pixel, all features are processed
but the extraction from each one is done with a corresponding traversal.
As a quick fix to allow for this behavior at least for specific commands,
this global (static) flag can be used to instruct the traversal not
to call ResetReading on the layer.
- Fixed some memory errors and leaks -- thanks valgrind, again!
2008-01-16 (1.0.06)
- FR #350112: Duplicate pixel handling -- starting implementation.
See discussion: http://starspan.casil.ucdavis.edu/doku/doku.php?id=fr_350112
2007-12-14 (1.0.05)
- FR #200332: Added --delimiter option, now used in:
function command
------------------- ------------
starspan_csv --csv
starspan_stats --stats
starspan_update_csv --update-csv
starspan_getCountByClassObserver --count-by-class
In --update-csv, the given delimiter is used for reading in the given
input CSV file and to generate the new CSV file.
2007-12-10 (1.0.04)
- Changes to compile StarSpan against GEOS 3.x.x
See GEOS_VERSION_MAJOR-conditioned code in:
traverser.h, traverser.cc
Other various changes consisted in dropping the geos::* namespace,
which is now handled in traverser.h
NOTE: Successfully tested against 3.0.0rc3 on various machines but
was unsuccessful against 3.0.0rc4 (latest at this date): an error
at link time relate with not finding destructor ~Coordinate or
something liket that.
2007-12-03 (1.0.03) Performance inprovement with spatial filter.
- traverser.cc: Spatial filtering is now used by default. In case no
spatial filtering is desired, define the environment variable
STARSPAN_NO_SPATIAL_FILTER.
Performance comparison with the --stats command on the following inputs:
vector: /proj/delta/gis/field_work/field_data/200706/data3/all_teams_nudged.shp
64 rasters: /proj/delta/raster/hymap/base/ref1_geo3/200706/*_ort
Rasters with intersecting pixels: 47
Rasters with No intersecting pixels: 17
'time' reported: real user system
With spatial filter: 133.63 76.34 16:35.81
No spatial filter: 20m10.507s 5m55.868s 1m23.537s
In this case the improvement gives a ~10 times speedup!
2007-12-01
- Testing the use of spatial filter to get features:
STARSPAN_USE_SPATIAL_FILTER=1 starspan ...
under tests/, for example:
make STARSPAN=starspan STARSPAN_USE_SPATIAL_FILTER=1 test_csv
2007-11-30 (1.0.02)
- --stats now accepts multiple rasters; each one processed at a time
- NOTE about the call observer->intersectionFound(OGRFeature* feature)
in Traverser::process_feature:
Particularly in the case of a GeometryCollection, it might be the
case that this feature is found to be an intersecting one even though
that no pixel will be found to be intersecting. Observers may in general
want to confirm the actual intersection by looking at the number of pixels
that are reported to be intersected.
2007-11-19
- Option --fields now also accepts "none"
- Fixed argument check for --RID
2007-11-16: Carlos Rueda
** Starting version 1.0.xx **
- configure.in to version 1.0.01
- --report too restrictive about inputs: fixed.
2006-3-25: perrygeo
- configure.in to version 0.998
- src/tranverser/polyqt.cc : relative epsilon instead of constant
2006-03-24: perrygeo
- Exposed the SUM statistic
- Removed NoData/Null Values from the stats calculations
- Calculate two new stats: MEDIAN and NULLS (ie number of nodata
values)
2005-11-17
tests/misc/LFS/: new code to test LFS
2005-08-18 (0.997)
- 0.997 created to synchronize the whole thing.
2005-08-17 (0.996)
- mksrcdist.sh: set DISTDIR to /tmp/DISTDIR-starspan/
The problem was that ./reconf on the exported contents was not
creating the files depcomp, missing, and install-sh, required
for a successfull ./configure; make; ... on the user machine.
It seems the reason is that automake finds those files in ../ or
../../ and then doesn't create new copies. I looked for an
option to force automake to create those files but didn't find
any; so a simple solution is to create the distribution in a
different directory not descending from this one.
2005-07-04 (0.996)
Refactoring on management of set of visited pixels (pixset) with
the goal of optimizing memory usage in the case of big features:
Traverser.h declares new classes PixSet and PixSet::Iterator
New source file: pixset.cc
PixSet abstracts the operations on a set of pixel locations and
PixSet::Iterator provides a means to scan the contained locations
in the set (I have followed the Java style for the iterator
instead of the C++ one).
The first implementation of PixSet and PixSet::Iterator is based
on the set<EPixel> structure as in the previous version; this is
a preliminary test before using a different approach.
2005-07-01 (0.995)
- Traverser: Put some variables as instance member to avoid
recomputation: pix_abs_area, pixelProportion_times_pix_abs_area.
- Traverser::rasterize_poly_QT revisited:
- all-discard case is now under the condition that pixelProportion > 0.0.
- Fixed comparison in condition to include the whole envelope
- Traverser.h _Rect.lowerRight() fixed bug which generated the
same rectangle representing a single pixel
These changes also fix bug #200097.
2005-06-18 (0.995)
STARSPAN_VERSION only needs to be defined in one place: configure.in
2005-06-18 (0.9941 - interim)
- CVS: removed generated files; new reconf script;
mksrcdist.sh.in updated to create public distribution.
- some refactoring
2005-06-06 (0.994)
- Added option --show-fields
- Elapsed time reported only if --verbose is given
2005-06-05 (0.994)
starspan.in: Fixed calls using the list of passed arguments; now
"$@" is used instead $*, which was wrong particularly to deal
with arguments containing spaces. Note also that just $@
(without the double quotes) won't work either.
2005-05-26 (0.994)
Version set to 0.994
Some minor documentation updates.
Removed: --RID_as_given
Added: --RID {file | path | none}
Style for RID values in output.
file : the simple filename without path
path : exactly as obtained from command line or field in vector
none : no RID is included in output
Updated: --csv now processing --RID
Check --raster_directory is only given with --raster @field scheme.
2005-05-21 (0.994)
PATH in starspan{.in} was not set to include GDAL and GEOS's bin/
directories. Fixed.
todo: check proper environment to run tests
2005-04-28 (0.993)
Hack in starspan_myErrorHandler (starspan_util.cc) as a workaround
in current GDAL code which doesn't implement SetScale/SetOffset
methods for some raster band types.
Traverser code cleanup (traverser.h, traverser.cc):
Removed old methods for rasterization of polygons:
processValidPolygon_FF(geos_poly)
processValidPolygon_BB(geos_poly)
Versions containing those methods are:
traverser.h,v 1.9
traverser.cc,v 1.10
starspan_countbyclass.cc: verbose messages and flush for each
finished feature.
Note: configure doesn't set execution permission to script
starspan. This flag is set by `make install' on destination.
For running the tests under tests/, I added a `chmod +x ../starspan'
to tests/Makefile. I discarded adding a `chmod +x starspan' to
configure.in (in AC_OUTPUT), as I'm not sure if that's portable.
2005-04-28 (0.99 -released)
Quadtree algorithm implemented for polygon rasterization:
New traverser/polyqt.cc.
Preliminary tests OK. The speedup over the flood-fill algorithm
with a polygon that contains 22860 pixels is:
time(flood-fill) / time(quadtree) = 98s/4s = 24.5 (!)
TODO: More tests; check the other goemetry types resulting from
intersections that are ignored.
starspan2.cc: shutdown calls to release resources: input data
objects and calls to CPLPopErrorHandler() and geos::Unload::Release().
mksrcdist.sh: using my developer account to export from cvs
(currently anonymous access to casil is not working.)
Version released today: 0.99
2005-04-26 (0.98beta)
Changes committed.
Removed temporary NEW-SOURCES-PENDING-MERGE-COMMIT/.
Pending: configure regeneration.
2005-04-21 (***** to-be 0.98beta )
Traverser: Finally implemented a flood-filling algorithm to
rasterize polygons. Temporary source files:(*)
NEW-SOURCES-PENDING-MERGE-COMMIT/traverser/traverser.h
NEW-SOURCES-PENDING-MERGE-COMMIT/traverser/traverser.cc
Other minor changes also pending for merge and commit:

2005-04-04
New BUILD.windows.txt with notes about compiling the whole
system in windows
2005-03-23 (0.963beta)
Makefile.props.templ: GDAL_SRC_DIR removed: we don't
need this any more as GDAL (from 1.2.6) already installs
vrtdataset.h in GDAL's PREFIX/include/.
traverser.cc: Fixed a bug related to rerunning a traversal
on new rasters. In particular starspan_csv.cc works on a
raster at a time. The symptom was that the first specified
raster was processed OK but not the others in a command line
like this:
starspan --raster R1 R2 ... --vector V --csv my.csv
The fix was in Traverser.removeRasters to add a call to
globalInfo.rasterPoly.empty(), which empties the contents
of the rasterPoly, so when addRaster is called, it gets
the new ring from the first given raster.
The news for end users is to say something like:
Fixed a bug in --csv command on multiple rasters which
made only the first given raster to be properly processed.
Hmm, while trying unsuccessfully my 'make test' target, I
noticed that GDAL 1.2.6 has a bug related with CreateCopy
which call new methods SetOffset/SetScale; these methods
are not implemented for envi raster bands so they inherited
from GDALRasterBand wich fail with a CPLError; That explains
this new behaviour. I have notified the GDAL dev newsgroup
about this situation to see what Frank says about that.
For now, the mini raster options ARE broken due to this
GDAL bug!
I just checkout the last gdal cvs snapshot and it seems
that the problem is still there (by looking at the code).
2005-03-23 (0.962beta)
Usage message reorganized: testing and other developer
oriented options are shown with --help-dev.
New method traverser.getPixelSetSize(), which is now
used in MiniRasterObserver.intersectionEnd().
New static method Stats.computeCounts() to count the number of
occurrences of each value in a vector<int>.
Method Traverser.getPixelSet() removed. Other minor changes
to documentation in traverser.h.
Added methods in Traverser:
getPixelIntegerValuesInBand(unsigned band_index, vector<int>& list);
getPixelDoubleValuesInBand(unsigned band_index, vector<double>& list);
which work on set of visited pixels in current feature.
Removed methods in Traverser:
getPixelIntegerValuesInBand(unsigned band_index, vector<CRPixel>* colrows, vector<int>& list);
getPixelDoubleValuesInBand(unsigned band_index, vector<CRPixel>* colrows, vector<double>& list);
StatsObserver: eliminated list of pixels in current feature. This
functionality is already provided by the traverser.
New option --count-by-class implemented in new observer
CountByClassObserver (starspan_countbyclass.cc). See starspan.h
for more information.
2005-03-04 (0.961beta)
starspan_update_csv.cc: simple printf-to-cout changes
Minor text updates in starspan script.
2005-02-26 (0.961beta)
Added option --separation <num-pixels> to include a separation
between minirasters in strip. Feature request #200074.
starspan_miniraster.cc: Since ENVI complains about "Unknown" projections
(which us the map info created by GDAL by default), I decided to set
this projection explicitly by using the projection from the (arbitrarely
chosen) first miniraster. Now ENVI opens the generated strips without
any complain. This fixes bug #200073
--report now also shows projection info for rasters.
starspan_miniraster.cc: workaround to GDAL bug which
generates repeated header items when FlushCache is called
multiple time on an ENVI dataset.
2005-02-19 (0.96beta)
--buffer <distance> [<quadrantSegments>]
If the parameter starts with '@', then it will be interpreted as the
name of the attribute from which the value will be obtained. Example:
--buffer @buf_distance 21
indicates that the buffer distance is to be taken from the field
buf_distance in the corresponding geometry feature; the quadrantSegments
is fixed to 21. This fulfills request #200066
--mini_raster_parity {even | odd | @<field>}
Implemented. This fulfills request #200069
--mr renamed to --mini_rasters
Tests pending for --buffer and --mini_raster_parity.
2005-02-19 (0.952beta)
- Making a source distribution. Example:
make dist VERSION=0.1
which is the same as:
./mksrcdist.sh 0.1
- polygon/ moved to libtests/ and NOT added to cvs (this is old stuff).
- java/ moved to libtests/ and ADDED to cvs.
2005-02-19 (0.951beta)
- new scheme to make source distribution (see mksrcdist.sh)
- source restructuring. These dirs were moved to src/:
csv jts raster rasterizers stats traverser util vector
2005-02-18 (0.95beta)
- Top-level sources moved to src/
2005-02-16 (0.95beta)
- 0.94beta released.
- starting 0.95beta
2005-02-16 (0.94beta)
- minirasterstrip:
- fid strip now also created. I tried to use RasterIO
documented capability of replicating a value; however it seems
it's buggy so as a workaround I'm just making the buffer the same
size of the region I want to fill with the replicated value.
"Background" value for the fid strip is -1 as normally FIDs start
from zero.
- loc strip now also created. (background values x=y=0 --arbitrarely)
- also set background value 0 for raster strip in all bands.
Visual tests in Envi: OK
Added test case in tests/Makefile with comparison of data files.
For some reason .hdr files are created with mapinfo repeated several
times (gdal bug?)
- Fixed a minor formatting in creation of filenames for minirasters to
keep compatibility with the way this used to be done with standard C:
Now: ... << setfill('0') << setw(4) << FID ...
2005-02-15 (0.94beta)
- mini raster strip command: implementation restarted based on
MiniRasterObserver. A subclass MiniRasterStripObserver uses a
list of basic info about each generated miniraster (mrbi_list)
to merge the minirasters into the final strip.
The basic functionality is now working (tested visually in envi).
Next:
- create the accompanying .fid and .glt rasters.
- delete temporary minirasters
(Note: starspan_miniraster_strip.cc no longer used; all this is
implemented in starspan_minirasters.cc)
- Comments about --O and --outformat proposed variations in:
http://casil.ucdavis.edu/tracker/?func=detail&aid=200072&group_id=48&atid=350112
2005-02-12 (0.94beta)
- starting 0.94beta
- I just grabbed the last GDAL cvs snapshot and build a fresh gdal. I see
that vrtdataset.h (among others that used to be under frmts) are now siblings
of gdal.h under GDAL_PREFIX/include/. So a future version of our Makefile
will use only the GDAL_PREFIX. (No more GDAL_SRC_DIR).
2005-02-11 (0.93beta)
- starting 0.93beta.
- New Makefile.props.fink (jgrn307)
- added INCLUDE += -I$(GDAL_SRC_DIR) in Makefile (jgrn307)
- More documentation in Makefile
- copyright.txt added
- README.txt now with a general description of the tool
- new doc/srccontents.txt (with old readme contents)
- TODO: clean up starspan script from particular settings!
2005-02-10 (0.92beta)
- Makefile changes and new target `dist' to create a source distribution
from current CVS repository. E.g:
make dist VERSION=0.92beta
created:
DISTDIR/starspan-0.92beta.tar.gz
2005-02-07 (0.92beta)
- Starting to work on new --mini_raster_strip option.
See starspan_miniraster_strip.cc (partially implemented)
- INSTALL.txt created (based on http://starspan.casil.ucdavis.edu/?Build)
2005-02-04 (0.92beta)
- setting up a test scheme: new directory tests/ and
tests/Makefile to apply tests.
New target `test' in master Makefile.
Structure under tests/ is as follows:
data/ Contains all required raster, vector, and other data
on which tests are to be performed.
expected/ Contains data used as expected outputs from starspan.
Currently it contains data generated by starspan itself
but that have been checked externally with Envi.
generated/ This is created and populated by running the
test cases in Makefile.
Currently the validation scheme is based on cmp-ing (binary comparing)
the outputs in generated/ with corresponding expected outputs in
expected/.
- new --buffer option. Also included a basic test case.
2005-02-02 (0.92beta)
- new traverser services to get access to set of visited pixel during
current intersecting feature.
- miniraster using nodata value to nullify pixels outside geometries.
2005-02-01 (0.92beta)
--nodata added
2005-01-24 (0.92beta)
All options with double dash.
New option --version.
2005-01-24 (0.92beta)
starspan_minirasters.cc revisited: Now using traverser scheme
(first tests..)
2005-01-23 (0.91beta)
Simplified dependencies scheme:
- No more external dependency on AGG. Now the following AGG headers
(from the agg22.tar.gz distribution) are kept under rasterizers/
agg_basics.h
agg_dda_line.h
(even these headers will eventually be eliminated after a pending
revision of the line rasterizer.)
- DBF format support dropped: no more shapelib dependency.
The following sources are no longer maintained:
starspan_db.cc
starspan_update_dbf.cc
In summary, the only dependencies are now GEOS and GDAL.
2004-11-13
New options: -raster_field, -raster_directory
starspan_csv_raster_field.cc
Working only for points.
MyPolygonizer eliminated; now geos::Polygonizer makes proper destruction.

2004-11-10 (0.9beta)
Quote fields in CSV if necessary.
Changes to allow the input rasters to be at different locations.
Do tests!
2004-10-21 (0.89beta)
Some cleanup: Raster, Traverser, Stats.
To improve performance on computation of integers:
Traverser#getPixelIntegerValuesInBand(..)
Stats::compute(vector<int>& values)
StatsObserver now uses integer extraction if no band is of
floating point type.
In particular, calculation of MODE should now be more efficient
because a map<int,int> is used.
Traverser::summary with some counters for a summary report.
2004-10-20
More checks for malformed (WKT) geometries.
Such a problem generates a GEOS exception but starspan was not
catching it.
2004-10-18
Starting to use geos::Polygonizer as a means to fix bad polys.
(geos::Polygonizer is not yet in the 2.0.1 official release, I'm using
the CVS snapshop.)
The idea is to node the segments defining a "bad" (self-intersecting)
polygon, and then polygonize the resulting multilinestring.
See Traverser#processPolygon().
Now working. But there are some memory leaks associated with
Polygonizer..
(my first test of Polygonizer was in java using JTS directly:
See java/src/starspan/tools/PolygonizerTest.java.)
2004-10-14 (0.88beta)
New option -RID_as_given: by default, RIDs are the filenames without
any path. With this option RIDs will take the filenames exactly as
given in the command line.
2004-10-12 (0.87beta)
Some cleanup and checks for memory leaks:
- StatsObserver.computeResults(): vector of values released.
- Traverser::processPolygon: geos_poly released.
- Traverser: pixset : Duplication of pixel is always checked
for all intersections types except for polygons.
pixset is reset on a per feature basis, so potential duplication
of pixels accross features won't be detected.
- There is a minor memory leak in GDAL 1.2.3 (geotiff.cpp:3787)
that is already fixed in CVS. I will wait for next GDAL release.
Option -skip_invalid_polys. By default all polygons will be processed.
2004-10-11 (0.86beta)
Traverser::processPolygon: now catches GEOS exceptions which
may occur when a pixel is intersected with a self-intersecting
polygon; to be more specific it seems the problem arises when
the self-intersection happens to be in the area involved in the
pixel/poly intersection.
Currently the exceptions are just ignored so the process can
continue.
An environmental variable STARSPAN_DUMP_POLYS_ON_EXCEPTION controls
if the involved polygons should be WKT-printed to stderr.
An appropiated solution to this case is PENDING.
See http://geos.refractions.net/pipermail/geos-devel/2004-September/001045.html
2004-10-08 (0.86beta)

traverser::processPolygon_point removed. Now intersection
of pixels and polygons are only done according to proportion of
intersected area (0.5 by default).
(previous revisions: traverser.cc,v 1.34, traverser.h,v 1.25)
GDAL note: Use -D_FILE_OFFSET_BITS=64 for C flags before
./configure'ing GDAL in case large file support (LFS) is not working
properly. (I fixed this kind of problem on pavo machine today.)

New scheme for -calbase command:
-calbase linkname output.csv stat1 stat2 ...
-vector V : with field linkname (eg. Cal_ID)
-speclib F : csv format: linkname,1,2,...,m
-raster R1 ... : images
stat1 stat2 ... are optional desired statistics from rasters; by
default AVG is calculated
This is based on the following additions/changes:
New method Traverser#setDesiredFeatureByField(fieldname, fieldvalue).
New starspan_getFeatureStatsByField
starspan_tuct2.cc: entry point: starspan_tuct_2(...)
First tests: OK
New scheme for stats calculation: now based on a band-oriented fashion,
which should be more efficient according to GDAL model although efficiency
also depends on the specific interleave of raster datasets; in particular
BSQ is the preferred interleave for band-wise calculations.
Included "mode" statistic.

starspan_stats.cc: new starspan_getFeatureStats(FID,vect,rast,stats)
to get statistics for FID in raster rast. StatsObserver was adjusted
to support the new service.
starspan_tuct1.cc: code for new ''-calbase outfile'' command.
This command expects inputs -vector V, -raster R1 R2 ...,
and (new) -speclib F.
starspan create outfile in CSV format with the following scheme:
FID,RID,BandNumber,FieldBandValue,ImageBandValue

starspan_stats: bug fixed: I was calling pixels.empty() instead
of pixels.clear()!
select_fields is now a pointer to a vector.
-stats: now it also process selection of fields (-fields ...)

-dump_geometries: new testing operation (implemented in
starspan_dump.cc) to generate plot of geometries and raster extent.
This provides a better control on visualization.
Output format is the textual form accepted by the Ptolemy Plot
library, http://ptolemy.eecs.berkeley.edu/java/ptplot/ .
A new extended usage option --view_geometries launches the
ptplotapplication tool.
typical usage:
starspan -vector V -raster R -dump_geometries mygeometries.csv
starspan --view_geometries mygeometries.csv
LineRasterizer: Now uses origin (x0,y0) to make a proper traslation
before calling the bresenham algorithm. Preliminary tests (via
--view_geometries) give now accurate results.
