FromWKB example

This example illustrates the use of converting a WKB to a geometry object.

import arcpy

fc = "c:/base/gdb.gdb/counties"

rows = arcpy.da.SearchCursor(fc, ['SHAPE@'])
studyarea = rows.next()[0]

# Create geometry to WKB
polyWKB = studyarea.WKB

# Convert WKB back to a geometry
polyGeom = arcpy.FromWKB(polyWKB)
