Batch convert raster to polygon

mlopezr95984 — Tue, 20 Apr 2021 02:33:46 GMT

Hello,

I have several raster files in a folder. I would like to convert them to polygons. Is there a way to run a batch?

Thank you

in a model in modelbuilder...

However, "several"? By the time you get the model running and tested, you could have probably done it manually several times over.

If this is a repetitive task then consider modelbuilder, but a python script would probably faster.

Easiest is to right-click the Raster to Polygon (Conversion) tool and select "Batch"

which is kindof like modelbuilder... but check the requirements to see if it suits your needs

Thank you Dan, this worked!

from arcpy import env

#Set environment settings

env.workspace = r"C:\Users\MD\Documents\Geos\RECLASS_FILES"

rasters = arcpy.ListRasters("*", "TIF")

for raster in rasters:

a= (str(raster))
b= (a[:-4])

outRaster = (r"C:\Users\MD\Documents\Geos\RASTER_TO_POLY\CAT10")

In_v= raster

arcpy.RasterToPolygon_conversion(In_v, outRaster + str(b) +".SHP", "NO_SIMPLIFY","VALUE")
