Hi,
I have written a wee python script to carry out viewshed analyses for each point of a point feature class.
In the point feature attribute table, I have added OFFSETA, OFFSETB, RADIUS1 and RADIUS2 as variables for the viewshed analysis.
However, it doesn't pick up those variables but uses the defaults (RADIUS1=0 etc). If I generate the viewshed manually it works, but not with the script.
As the point feature class contains hundreds of points, I certainly don't want to generate each viewshed manually! Any help is very much appreciated!!

P.S: this is the little script, that works fine otherwise
# Import arcpy module
import arcpy
# Check out any necessary licenses
arcpy.CheckOutExtension("3D")
# Local variables:
dhm = "C:\\dhm_combined"
Standorte = "C:\\Standorte_3_test.shp"
cur = arcpy.SearchCursor(Standorte)
for row in cur:
feat = row.Shape
print row.Nr
turbine = str(row.Nr)
vs = "D:\\arctemp\\vs_manuell_"+turbine
# Process: Viewshed
arcpy.Viewshed_3d(dhm, feat, vs, "1", "FLAT_EARTH", "")
del cur, row
