How to multiply two rasters in Python?
I wrote script:
import arcpy
from arcpy import env
arcpy.CheckOutExtension('Spatial')
#folder with pixels: 0-bad and 1-good value
env.workspace = "B:\mask"
masks = arcpy.ListRasters("*", "")
#folder with value of pixels from 0 to 255
env.workspace = "B:\raster"
rastlist = arcpy.ListRasters("*", "")
for mask in masks:
maskname = str(mask)
for raster in rastlist:
rastname = str(raster)
if maskname[:25]==rastname[:25]:
r= mask*raster
env.workspace = "B:\MODIS\MOD15A2\converted\n"
r.save(rastname)
But it doesn't multiply rasters. It is some problem with :
r= mask*raster
In Python window shows :
"Runtime error <type 'exceptions.TypeError'>: can't multiply sequence by non-int of type 'unicode'"
