I get the following error when trying to transform points stored in ST_GEOMETRY EPSG 32198 into WGS 84 EPSG 4326:

ORA-20603: Spatial References are not compatible.
ORA-06512: at "SDE.ST_GEOMETRY_SHAPELIB_PKG", line 720
ORA-06512: at "SDE.ST_GEOMETRY_OPERATORS", line 2623

All our data is stored in EPSG 32198 and according to ( this projection is based on datum NAD83 ESPG 4269.

It looks like ST_TRANSFORM is having a hard time to convert NAD 83 EPSG 4269 based projection (like 32198) into WGS 84 EPSG 4326. Which I believe to be a very simple task for any GIS software. The conversion between them, at least in North America should be straight forward.

Weird isn't it?

The work around I found was to use NAD 83 EPSG 4269.

And it worked!

Hope this can help someone!
