How do I create an Initial Zero raster? I am trying to implement an error analysis for DEM following the tutorial in this link: http://webhelp.esri.com/arcgiSDEsktop/9.2/index.cfm?TopicName=Performing_error_analysis, but my model crashes in the beginning of the second iteration. It might be that i got the zero raster wrong, I used conditional to generate it: con(dem, 0). My model is attached.
