Add more tests to parse GeoTIFFs with custom CRSes #17
Description
A GeoTIFF can be defined by either an integer EPSG code or by a custom CRS description.
The integer EPSG code is a very simple case. We can just pass the EPSG code to pyproj.CRS.from_epsg.
The custom CRS is more difficult to parse. In #16 we're adding an implementation partially written by Claude. We have one test, using developmentseed/geotiff-test-data#16 as the data file.
It would be great to add more tests for more sorts of images that are defined by a custom CRS.
Tasks
- Find more COGs defined by custom CRS (not by EPSG code). Or create some from scratch.
- Add more such COGs to geotiff-test-data
- Add these test paths to the pytest parameterizations in
test_crs.py
FYI: when a COG is not defined by an EPSG code, the CRS field in rio cogeo info is a full WKT2 string: https://github.com/developmentseed/geotiff-test-data/blob/0224b1c522d9b32a37b4b95fe92298b9a0f38f2b/real_data/nlcd/nlcd_landcover_info.md?plain=1#L24
