v0.2.0

• Added gio.find_closures() to automatically find closing contours in a grid. Also added short notebook about it to the docs. Many thanks to Rob Gooder for hugely improving this algorithm.
• Development note: switched to PEP621-style build system, using only pyproject.toml.
• Now also building on and supporting Python 3.11.
• Moving to more conventional semantic versioning.

v0.2.0-rc1

Testing CI and new build process.

v0.1.7

• Fixed bug issue #26, which garbled string comments in array_to_zmap().
• Implemented enhancement issue #17. Created gio.unmap_to_dataarray(), putting the guts of the algorithm into its own library, unmap, which is now a dependency of gio. The library only produces NumPy arrays, so gio adds the xarray wrapper and a couple of extra options.

v0.1.6

• Added the zmap module, with functions for reading ZMAP files (read_zmap()) and for writing files starting from an xarray.DataArray or from a NumPy array.
• Added xarray.DataArray accessor (in xarray.py) to save in ZMAP and OpendTect formats. The plan is to add more target formats the the accessor, according to need.
• Added tests for the ZMAP components. Removed run_tests.py and put the pytest options in setup.cfg, which seems cleaner.
• Started trying to maintain this file properly!
• Note that there are two ‘work in progress’ files, esri.py and usgs.py, which will eventually read some common DEM formats.

Some readers, no writers, no tests, very basic.
