geojsonio v0.7.0

NEW FEATURES

• geo2topo() gains a new parameter quantization to quantize geometry prior to computing topology. because topojson_write() uses geo2topo() internally, topojson_write() also gains a quantization parameter that's passed to geo2topo() internally (#138) thanks @pvictor

MINOR IMPROVEMENTS

• use package sf instead of sp in topojson_read(). note that the return object is now class sf instead of classes from the sp package (#144) (#145)
• the type parameter in topojson_json() now set to type="auto" if the input is an sf/sfc/sfg class object (#139) (#146)
• fix to geojson_list.sfc() for changes in sf >= v0.7, which names geometries, but that's not valid geojson (#142)

DEPRECATED AND DEFUNCT

• The two linting functions in this package, lint() and validate()
  are now defunct. They have been marked as deprecated since v0.2. See the package geojsonlint on CRAN for linting geojson functionality (#135) (#147)

NEWS

NEW FEATURES

• topojson_write() gains a new parameter object_name. With it you can set the name for the resulting TopoJSON object name created. As part of this geo2topo() also gains a new parameter, similarly called object_name, that does the same thing as for topojson_write(). (#129) (thanks @josiekre) PR (#131)
• As part of PR (#132) we added a new function geojson_sf() to convert output of geojson_list() or geojson_json() to sf package classes - as an analog to geojson_sp()

MINOR IMPROVEMENTS

• geojson_json() gains option with the type parameter to skip a coercion to the geojson package class geoclass. Using type = "skip" you can skip the geoclass class coercion, which in some cases with large datasets should have performance improvements (#128) PR (#133)

BUG FIXES

• A bug arose in geojson_sp() with the newest version of rgdal. This was resolved by using the sf package instead to read GeoJSON. This had a knock-on benefit of speeding up reading GeoJSON. In addition, sf is now in Imports instead of Suggests (#130) PR (#132)

geojsonio v0.5.0

NEW FEATURES

• gains new function geojson_atomize to "atomize" a FeatureCollection
  into its features, or a GeometryCollection into its geometries (#120)
  via (#119) thx @SymbolixAU
• gains new functions topojson_list and topojson_json for converting
  many input types with spatial data to TopoJSON, both as lists and
  as JSON (#117)
• geojson_json uses brief output provided by the geojson
  package - this makes it less frustrating when you have an especially
  large geojson string that prints to console - this instead prints a
  brief summary of the GeoJSON object (#86) (#124)

MINOR IMPROVEMENTS

• doing a much more thorough job of cleaning up temp files that are
  necessarily generated due to having to go to disk sometimes (#122)
• @ateucher made improvements to geojson_json to make type
  parameter more flexible (#125)

BUG FIXES

• Fixe bug in topojson_write - we were writing topojson file, but also
  a geojson file - we now cleanup the geojson file (#127)

geojsonio v0.4.2

BUG FIXES

• Fix package so that we load topojson-server.js from within the
  package instead of from the web. This makes it so that the
  package doesn’t make any web requests on load, which prevented package
  from loading when no internet connection available. (#118)

geojsonio v0.4.0

NEW FEATURES

• Gains new functions geo2topo, topo2geo, topojson_write, and topojson_read for working with TopoJSON data - associated with this, we
  now import geojson package (#24) (#100)

MINOR IMPROVEMENTS

• Updated vignette with details on the GeoJSON specification to the new
  specification at https://tools.ietf.org/html/rfc7946 (#114)

geojsonio v0.3.8

MINOR IMPROVEMENTS

• geojson_write and geojson_json now pass ... argument through to
  rgdal::writeOGR or jsonlite::toJSON depending on the class/method. For
  those methods that use the latter, this now allows setting of the na
  argument to control how NA values are represented in json, and the
  pretty argument to control whether or the resulting json is
  pretty-formated or compact (#109) (#111)
• Spelling/grammar fixes, thanks @patperu ! (#106)

BUG FIXES

• geojson_json and geojson_write now convert unsupported classes to
  their basic class before conversion and/or writing to geojson. This was most
  commonly occurring with fields in sf objects calculated by sf::st_area
  and sf::st_length which were of class units. (#107)
• Fixed a bug occurring with GDAL version >= 2.2.0 where the layer name in
  a geojson file was not detected properly (#108)

geojsonio v0.3.2

BUG FIXES

• Fix to tests for internal fxn convert_wgs84 to do minimal test of
  output, and to conditionally test only if sf is available (#103)

geojsonio v0.3.0

NEW FEATURES

• geojson_json, geojson_list, and geojson_write gain new S3 methods:
  sf, sfc, and sfg - the three classes in the sf package (#95)
• geojson_json, geojson_list, and geojson_write gain two new
  parameters each: convert_wgs84 (boolean) to convert to WGS84 or not (the
  projection assumed for GeoJSON) and crs to assign a CRS if known
  (#101) (#102)

MINOR IMPROVEMENTS

• geojson_json() for non-sp classes now only keeps seven decimal places
  in the coordinates. This follows the default that GDAL uses.
• Now namespacing base package calls for methods/stats/utils
  instead of importing them
• Improved documentation for method parameter in geojson_read
  clarifying what the options are for (#93) thanks @bhaskarvk
• Internal fxn to_json now defaults to 7 digits, which is used in
  as.json and geojson_json (#96)

BUG FIXES

• Fix to geojson_read to read correctly from a URL - in addition
  to file paths (#91) (#92) thanks @lecy
• Fix to geojson_read to read non-.geojson extensions (#93)
  thanks @bhaskarvk

geojsonio v0.2.0

MINOR IMPROVEMENTS

• Major performance improvement for geojson_json() - moved to
  reading in json with readr::read_file() (#85) thanks @javrucebo !
• Now requiring explicit versions of some package dependencies
• Removed the startup message

BUG FIXES

• Changed file_to_geojson() to use httr::write_disk() instead of
  download.file() (#83) thanks @patperu

DEPRECATED AND DEFUNCT

• The two linting functions in this package, lint() and validate()
  are now deprecated, and will be defunct in the next version of this
  package. See the new package geojsonlint on CRAN for linting
  geojson functionality (#82)

geojsonio v0.1.8

NEW FEATURES

• New method geojson_sp.json() added to geojson_sp() to handle json
  class inputs

MINOR IMPROVEMENTS

• Added encodin="UTF-8" to httr::content() calls

BUG FIXES

• geojson_write() didn't overwrite existing files despite saying so.
  New parameter added to the function overwrite to specify whether to
  overwrite a function or not, which defaults to TRUE (#81)
  thanks @Robinlovelace !
