Using Reclassify to do NoData Values

SoratoMarques — Wed, 13 Sep 2023 13:29:08 GMT

Hi,

I have one raster and would like to transform all values between -0,9 - 0 like 1 value, and 0 - 0,9 like NoData.

How can I to this in python?

Thank´s

SoratoMarques,

This is a standard function that has an arcpy sample as part of the help about this function.

Do you have the spatial analyst or 3D analyst extension? One of these is necessary for access to the tool.

If none of this helps you solve this issue, what is the error or problem with the methodology?

Regards,
- Jim

arcpy.gp.Reclassify_sa(negativo_tif, "Value", "-0,900000 0 1;0 0,900000 NODATA", reclass_negavt_tif, "DATA")

I would suggest using the Con tool instead
