Introduction
Many parts of FME rely on GDAL, both directly and indirectly. The migration to GDAL 3 and PROJ 6 in FME 2020, has primarily altered behavior that has to do with either storing a description of a coordinate system or recognizing a coordinate system description.
What is Affected?
These changes affect the following FME components:
Any reader/writer where a coordinate system is stored with the data
Includes Well Known Text formats and Esri WKT, especially if an uncommon coordinate system is used
Almost all GDAL-based formats
May include formats that use an authority code to look up coordinate systems
Does not include formats that always use the same implied coordinate system (for example, most geospatial-database-as-a-service web platforms just use LL-WGS84).
A GeoTIFF reader/writer or a reader/writer that contains GeoTIFF specifications
Any use of the CoordinateSystemDescriptionConverter transformer
Use of coordinate systems based on the South American Datum of 1969
Use of coordinate systems based on Militar-Geographische Institut (Austria)
Any FME components that consume WKT in another format
