Reading/Writing ArcGIS geodatabase Raster field data type

_
Badge

I have a feature class in a file geodatabase with a Raster data type field, whose values I want to write to an SDE feature class with an equivalent Raster field.

When I use the GEODATABASE_FILE reader, the raster column is not listed in the resulting feature class. Likewise with the FILEGDB. To make sure I wasn't missing something I tried the GEODATABASE_FILE_RASTER_DATASET and GEODATABASE_FILE_RASTER_CATALOG readers, which, as expected, would not recognize the feature class.

When I use the GEODATABASE_SDE writer the raster field is also omitted. Again, trying the raster readers, GEODATABASE_SDE_RASTER_CATALOG and GEODATABASE_SDE_RASTER_DATASET did not recognize the feature class.

Does FME handle the ArcGIS geodatabase Raster field type?

 

Using FME Version 2019.0.1.0 Build 19253

Hello @_trent

 

 

I do not see any record of us being able to read this Data type in the past. Are you able to share a sample Geodatabase that contains this Raster Data type within a Feature Class? This would allow us to perform some tests to see if we can get the Raster datatype exposed.

Attached is a zipped file geodatabase with a feature class that has a raster field.

In terms of writing, using the blob field type is a potential workaround e.g. converting form raster to blob with the RasterExtractor then writing out: https://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_Transformers/Transformers/rasterextractor.htm

I haven't used the raster data type in geodatabase for a long old time so I'm limited there!
