Fiona 1.8.5

Sean Gillies — Sat, 16 Mar 2019 17:23:44 GMT

Fiona, the Python library for reading and write geospatial vector data that is used by GeoPandas, has a new 1.8.5 release with significant bug fixes and performance improvements. See the change log for details and pip install -U fiona to upgrade.

Another reason to upgrade is that the wheels on PyPI now include GDAL 2.4.0, a version with many core and format driver improvements, including support for GeoJSON feature sequences and WebP compression in GeoTIFFs.

Fiona 1.8.0

I forgot to blog this on the day we released it. I'm sick today and will keep this post brief. Fiona 1.8.0 is on PyPI. The release announcement is here: https://github.com/Toblerity/Fiona/releases/tag/1.8.0. There will be a 1.8.1 release soon.

Fiona 1.8b1

Fiona 1.8b1 is in the cheese shop today while supplies last: https://pypi.org/project/Fiona/1.8b1/. There are changes since 1.8a3, none of them breaking. Please, if you can, run pip install fiona==1.8b1 to help test this prerelease.

Deprecations

Collection slicing has been deprecated and will be prohibited in a future version.

Bug fixes

Rasterio CRS objects passed to transform module methods will be converted to dicts as needed (#590).
Implicitly convert curve geometries to their linear approximations rather than failing (#617).
Migrated unittest test cases in test_collection.py and test_layer.py to the use of the standard data_dir and path_coutwildrnp_shp fixtures (#616).
Root logger configuration has been removed from all test scripts (#615).
An AWS session is created for the CLI context Env only if explicitly requested, matching the behavior of Rasterio’s CLI (#635).
Dependency on attrs is made explicit.
Other dependencies are pinned to known good versions in requirements files.
Unused arguments have been removed from the Env constructor (#637).

Refactoring

A with_context_env decorator has been added and used to set up the GDAL environment for CLI commands. The command functions themselves are now simplified.

A 1.8.0 final release is scheduled for the end of this month.

Fiona 1.8.0 Final Push

A 1.8.0 release of Fiona, OGR's new/nimble/nother API for Python, is one of my work goals for the last quarter of 2018. In fact, I'm going to try to wrap it up by Halloween. I published wheels for 1.8a3 to PyPI on Monday and would be much obliged if you would try them out: pip install fiona==1.8a3.

Fiona and Rasterio releases

Sean Gillies — Tue, 02 Sep 2014 06:00:00 GMT

Like everyone else, I'm making releases before FOSS4G. Fiona 1.2 has a bunch of bug fixes and new features (contributed largely by René Buffat) and Rasterio 0.12 has new CLI commands and options. I'll be talking about these packages and their design and use first thing Wednesday morning (September 10) at FOSS4G. I've also got some things to say about Python programming and geographic data that are not specific to Fiona and Rasterio.

The big deal, however, will be the release of Shapely 1.4 on September 9. This is the first version with major new features since the project made the jump to Python 3. There will be quite a lot of new stuff in 1.4 including better interaction with IPython Notebooks, vectorized functions, an R-tree, and lots of speedups. It's been a group effort largely motivated by development of visualization and analytic frameworks: Cartopy and GeoPandas. Joshua Arnott and Jacob Wasserman in particular have been putting a lot of time into making Shapely better and faster over the past couple of weeks. If you're a Shapely user, please do something nice for these two the next time you see them.
