I'm trying to run multiple viewsheds in ArcGIS 10, reclassify these rasters and finally add them together. This is for a wind farm project where we need to repeat multiple viewsheds from various turbines and therefore the process lends itself particularly well to Modelbuilder.
My problem is that I am unable to get the Collect Values and Cell Statistics tools to work together to locate the reclassified rasters and add them together (see lower part of my model below):
Can anyone show me how to correctly use the Collect Values tool to point to the reclassified rasters and use the Cell Statistics tool to sum these up?
Update with working model
Here is the revised (working) model for cumulative viewsheds. The user simple needs to point the model to a list of turbine point files for it to run. Thanks all.
