Rodrigo What about trying it with fewer contour lines (i.e. select about 80%)? What about in a standalone script? How many columns and rows does the output raster have? -Steve

Correct, however, there are still constraints and you might want to read How large a DEM can the TopoToRaster tool create?

...we'll need info 🙂 I would guess that it is related to the output raster size and/or number of inputs. Try changing the output cellsize or limiting the number of input contours. We have done much work on trapping the "out of memory" errors so this may be non-reproducible in versions post 10.2 BTW, TopoToRaster is written in Fortran and that is most likely the reason for throwing this error. -Steve

Peter Wilson why did you not consider any of Spatial Analyst's reclass tools? They now support muti-core processing -Steve

I thought that the GALayerToGrid tool gave you that result. Please can you create a MapPackage and email it to me ([email protected]) -Steve

Ravi You do realize that the EmpiricalBayesianKriging geoprocessing tool can output to a geostatistical layer or to a raster or to both? -Steve

Do you have any environments set? Did you change the cell size? What do you get from GALayerToContour? and, all output from the interpolations are floating point.

Ravi Please post an image of the preview page in the Wizard. Do you have any environments set? Did you change the cell size? What do you get from GALayerToContour? BTW Data->Export to Raster from the TOC does not work against a GA layer -Steve

A good idea, initially, might be to work with a subset of your data, say 3 rasters and in ArcMap zoom to a single pixel and use identify to get the value of all 4 (3 input and 1 output from CellStats) at that location.

for testing purposes I'd include (see highlighted 3 lines) for i in inraster: flds = ("VALUE", "COUNT") dct = {row[0]:row[1] for row in arcpy.da.SearchCursor(i, flds)} sumcnt = sum(dct.values()) dct1 = {k:v for (k,v) in dct.items() if k >= 10} sumcnt1 = sum(dct1.values()) percentage=(float(sumcnt1)/float(sumcnt)) print i,percentage arcpy.CalculateStatistics_management(str(i)) maxValue = arcpy.GetRasterProperties_management(str(i), "MAXIMUM") print maxValue newraster = ExtractByAttributes(str(i), "VALUE>=10") outname=os.path.join(outws,str(i)) newraster.save(outname) and the same for newraster

Golden Please try Neil's suggestion and I'm sure that you'll get what you want. By default we use nearest neighbor resampling when displaying a raster and you can change it to bilinear or cubic to get a smoother look. -Steve
