Hi all.
I need to identify (and convert) multisurface /curve polygons in a GDB.
The GDBs contain one feature class with many polygons: some of these records are multipart polygons. The data I am working with comes from uncontrolled sources using different GIS programs, so the GDBs are put through a workbench to identify obvious spurious geometries like self-intersections (this works well). However, I am having a recurring problem where the downstream processes in other systems are failing due to multisurface /curve polygons.
I have tried exposing the fme_type and geometry, but they are always “fme_areas”. However, if I run GDAL ogrinfo tool identifies lots of Multisurfaces, some are also CURVEPOLYGONs. For example, GDB today with 8 records had 64 multisurfaces.
Any anyone help point me in the right direction for how I might Id these issues in FME, or incorporate the GDAL tool somehow?
Note: I cannot share example data due to its sensitive nature.
Many thanks
