Convert File GDB to PostGIS Database
HowTo:File GDB Feature to PostGIS Database
The goal of this post is to get our data from a File GDB to a format that GeoServer can use, specifically a PostGIS GDB. If we try and use a shapefile, the field names will be truncated and this will invalidate your schema that you have worked so hard to conform to the USGIN schema standards.
*Only works for 10.x and up geodatabases. You need to upgrade your gdb to 10.x if you are using an older geodatabase.
