I started to develop in Python for GIS since three months and It's really great! I have to combine three versions of File GDBs into one, but the main problem is that the schema has advanced from GDB1 to GDB2: some fields name have changed and in addition, there is a raster field type column in the tables. I could have simply load the two precedent versions into even a dictionary than using arcpy.da module inserting them in the final version, using corresponding columns and and filling empty columns with null, but there is no way to download and upload raster field. I found a way to download, but not for uploading it. Can somebody help?
