I have an Arcgis (10) model which has 2 process that need to be run sequentially.
The 1st process is a python script that creates multiple rasters, but that output is not known to Model Builder, therefore I can't use it as a precondition. Or at least not as outline in Example #1 in that page. Maybe there's another route I haven't discovered.
The 2nd process needs those rasters in order to operate. How do I let #2 know when #1 is complete so it may start execution?
To reproduce build a model with:
Process_1: a script which runs PolygonToRaster several times, converting each field in the attribute table to a raster (here, but field list will need to be edited).
Process_2: Run LessThanFrequency Spatial Analyst tool on the results (but really the tool doesn't matter).
