From my experience, for the rasters it looks like Sedona reads the metadata from the Geotiff file: * [RS_FromGeoTiff](https://sedona.apache.org/1.4.1/api/sql/Raster-loader/#rs_fromgeotiff) Question: Is this correct (if yes => document it)? What are the limitations? eg. what metadata it cannot interpret (=> document it) For the vectors it depends: * [ST_GeomFromWKT](https://sedona.apache.org/1.4.1/api/sql/Constructor/#st_geomfromwkt). Here it is unclear what is the default [srid](https://en.wikipedia.org/wiki/Spatial_reference_system)? Also the documentation should contain a reference to the wikipedia article: https://en.wikipedia.org/wiki/Spatial_reference_system * [ST_GeomFromGeoJSON](https://sedona.apache.org/1.4.1/api/sql/Constructor/#st_geomfromgeojson): I assume it reads the CRS from the geojson file (if correct then document it) and what happens if it is not defined in the geojson? I believe if we can document those aspects then a lot of users will benefit (especially those that are more new to geospatial coding) -- This is an automated message from the Apache Git Service.
