Hi all,   I am trying to loop a tool and with every result of the loop to add it to the last. I have a default raster created (all 1's) to add the first instance too. I have tried collect values and then cell statistics, but as the list in collect values grows with successive looping, the cell statistics slows way down. I figure that if I just do an addition it will only ever have two rasters to think about at once. Naturally, I am in modelbuilder, but if you have python ideas, that could work.   Here is basically what I am trying to do:   In raster = RAS1 Out Raster = RAS2 SUM = RAS3 Shape = SHP1   For each record in SHP1   RAS2 = Process of SHP1 record and RAS1   RAS3 = RAS2 + Last RAS3   next   Thanks,   David     P.S. I have no idea how this new forum works, sorry if this ends up somewhere strange. ... View more

Hi all, I have a model where there is an iterator in the middle that takes a row selection from an input feature class, selects features from a separate process based on that row selection, and calculates a value for that selection. There are 30-40 rows that will be iterated. My model keeps re-processing the static end result before the iterator. Sorry if I am butchering the explanation of this, maybe the image will explain it a little better.... Thoughts on how to make the model run the process before the iterator only once? I need this process in there as I may need to re-run this as my inputs are updated. Thanks, ... View more

Hi All, The title tells you what I am doing. I cannot get the focal statistics to work within raster calculator which is within model builder. I have dumbed it down to just focal statistics inside of the raster calculator just to work through it and I am stumped. I have tried: FocalStatistics( "%TPI%", NbrRectangle(5,5, "CELL"), "MEAN", "") FocalStatistics( "TPI", NbrRectangle(5,5, "CELL"), "MEAN" ) - this works in raster calculator outside of modelbuilder FocalStatistics( "%TPI%", NbrRectangle(5,5, "CELL"), "MEAN" ) FocalStatistics( "%TPI%", NbrRectangle( 5, 5, "CELL"), "MEAN", "") What is modelbuilder looking for from me here????? erg ...

Hi All, I have a function I want to apply to a raster. I have multiple rasters, each will need this function applied. Here is the function: ( 11.16 * Sin( FocalStatistics( "%Name%", NbrRectangle( 3, 3, ???CELL??? ), "MEAN", "" ) ) / ( 0.765 + 2.625 *  FocalStatistics( "%Name%", NbrRectangle( 3, 3, ???CELL??? ), "MEAN", "" ) ) ) / ( 11.16 * Sin( FocalStatistics( "%Name%", NbrRectangle( 3, 3, ???CELL??? ), "MEAN", "" ) ) / ( 0.765 + 2.625 *  FocalStatistics( "%Name%", NbrRectangle( 3, 3, ???CELL??? ), "MEAN", "" ) ) + 1 ) As you can tell I have instigated 'iterate rasters' to get the %Name% input. I have this function currently stored in raster calculator within model builder. When I try and run the tool it crashes out saying that the raster does not exist.....it exists so obviously I am referencing it wrong inside of raster calculator but i don't see where I am going wrong. I am running 10.1. Any help would be appriceated. ... View more
