arcgis-desktopmodelbuilderreclassify
I have a model which buffers line features by a variable and then rasterizes them. I then need to reclassify before I am finished processing.
My issue is that I cannot access the values to reclassify in the model because they have not been created yet… I have tired to use the add field button in the tool and generalize the reclassification I need (very simple – nodata is 0 and all values 0 – 100 are 1 so I get 0 or 1 in my raster…
you can do this with arcpy, if you want. In this code, any input cell with a value 9999 will be set to NoData in the output raster, and the remaining cells will retain their original value.
import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outSetNull = SetNull("elevation", "elevation", "VALUE = 9999")
outSetNull.save("C:/sapyexamples/output/outsetnull")
you can read Conditional evaluation with Con and Set Null (Spatial Analyst) from ArcGIS Resource Center...
Syntax
SetNull (in_conditional_raster, in_false_raster_or_constant, {where_clause})
i hope it helps you...
You can actually do this in model builder without python but it is finicky and a bit of a workaround.

Use the Add Entry selection in the Reclassify window. The screenshot shows the values you will need to enter.
