To create a unique list of values from a field inside a cursor would repeat that for every feature, while the list remains the same. If I understand correctly, you want to construct a path (string) and store that in a field. You could use this: import arcpy, os Ausgabepfad = r"R:\Karto\Bierer2014\Datenabgabe\20150113_Brandt\raster" fgdb = "RasterCatalog.gdb" # you're not using this arcpy.env.workspace = os.path.join(Ausgabepfad, fgdb) # you're not using this ext = ".jpg" fc = os.path.join(Ausgabepfad, "Orthos_Nummern.shp") fld_oid = "OBJECT_ID" # or: arcpy.Describe(fc).OIDFieldName fld_out = "YourOutputFieldName" # should exist in shapefile rows = arcpy.UpdateCursor(fc) for row in rows:     path = os.path.join(Ausgabepfad, "{0}{1}".format(row.getValue(fld_oid), ext))     row.setValue(fld_out, path)     curs.updateRow(row) # or if you have a version >= 10.1 SP1, you could use the arc.da.UpdateCursor flds = (fld_oid, fld_out) with arcpy.da.UpdateCursor(fc, flds) as curs:     for row in curs:         row[1] = os.path.join(Ausgabepfad, "{0}{1}".format(row[0], ext))         curs.updateRow(row) ...

For the point featureclasses you can use the Spatial Join to join the elevation from the closest GPS point to the features. There are a lot of GPS points around the features, but the spatial join will only pass the data of the nearest feature. In this case I didn't much variation in the elevation, so that will probably not be an issue. Add the table to the TOC, right click on the table and select Display XY data: For the feature layer that is added enter the properties, activate the Fields tab and switch off all the fields that aren't relevant (this will avoid them to be joined to your features): Just leave the one with the elevation switched on (I assume it is ProjectedZ). Next right click on the featureclasses you want to enrich with the elevation, and select Join and Relates..., and Join. Select Join data from another layer based on spatial location, select the XY events (GPS data), select each point will be given all the attributes..., specify the output and click OK. A new featureclass will be created with the elevation added and a field with the distance between the features and the GPS point from which the elevation was joined. For points this is easy, for lines you cannot do this. The GPS points are also to sparse to interpolate the elevation and create a surface (TIN). Although you could try and use that to convert the lines into 3D lines. Another possibility would be to interpolate the elevations between nodes with a GPS point close, but that would require some programming. ... View more

When creating the field the field scale sets the number of decimal places stored in a field. This parameter is only used in Float and Double data field types. ... but:  If the input table is a personal or file geodatabase the field scale value will be ignored. You can change the display properties of a field. In the attribute table, right click on the field header (the name) and select "properties". Next click on the button next to Numeric: In the numeric format dialog, change the number of decimals: ... View more
