pycrs.elements.datums module
Named datum classes that can be created or parsed.
Functions
def find(
datumname, crstype, strict=False)
Search for a datum name located in this module.
Arguments:
- datumname: The datum name to search for.
- crstype: Which CRS naming convention to search (different CRS formats have different names for the same datum).
- strict (optional): If False, ignores minor name mismatches such as underscore or character casing, otherwise must be exact match (defaults to False).
