########## Geospatial.md: ########## @@ -44,8 +44,57 @@ locations on Earth. The default CRS `OGC:CRS84` means that the geospatial features must be stored in the order of longitude/latitude based on the WGS84 datum. -Custom CRS can be specified by a string value. It is recommended to use an -identifier-based approach like [Spatial reference identifier][srid]. +Non-default CRS values are specified by any case insensitive string that uniquely identifies a coordinate reference system associated with this type. Review Comment: Regarding case-insensitivity, I agree it does not make sense for PROJJSON. However, I think it would be helpful to have it for the other three cases. It specifically removes the ambiguity as to whether `SRID:<identifier>` or `srid:<identifier>` are both valid or not, and same for the `<authority>:<code>` and `projjson:<able_property_name>`. -- This is an automated message from the Apache Git Service.
