or look at http://www.arcgis.com/home/item.html?id=22d6a18db6e246a08a9411fcc5a1f32d if you only have ArcGIS 10

Why not use TopoToRaster as it was designed from creating DEMs. And BTW, it uses thin plate splines. Steve

Anke In ArcMap (Python window) or via a Python script, do the following import arcpy arcpy.GetSystemEnvironment('AGSDESKTOPJAVA') Navigate to the folder printed above and navigate further into java\jre\bin do you have java.exe in that folder? Also look and see if you have a system environment variable called AGSDESKTOPJAVA and it'll point to what is printed by arcpy.GetSystemEnvironment('AGSDESKTOPJAVA') Regards Steve

Julian You'll have to write your own. TopoToRaster, however, has many diagnostic outputs that can be used to assist in fitting a good surface. Regards Steve

In versions prior to ArcGIS 10 we wrote the output to .shp and then converted to whatever format you wanted. However, from ArcGIS 10 we natively write to the requested format. Therefore, if you're using ArcGIS 10+ you can output to file geodatabase and you won't hit the 2.1GB file limit. Regards Steve

Ellie We made a big change to TopoToRaster in ArcGIS 10.1. http://resources.arcgis.com/en/help/main/10.1/index.html#/Spatial_Analyst_toolbox/016w00000047000000/ You may also want to look at http://blogs.esri.com/esri/arcgis/2012/08/13/how-large-a-dem-can-the-topotoraster-tool-create/ If you can isolate the problem please send it to me (slynch@esri.com) Thanks Steve

Can you isolate the input data and run it (the 13th one) as a geoprocessing tool in ArcMap?

Can you attach one of these problematic ASCII files?

Phil 1) run the IDW Geostat geoprocessing tool and specify an output geostatistical layer name (eg. galyr) and don't specify an output raster name 2) run the SetModelParameter geoprocessing tool with - Input geostatistical model source = galyr (the ga layer you created above) - Parameter XML Path = /model/value[@name='Power']/@auto - Parameter value = true - Output model = c:\temp\optimized.xml 3) run the Create Geostatistical Layer geoprocessing tool with - Input geostatistical model source = c:\temp\optimized.xml - Input dataset = the feature class and field you used in #1 above - Output geostatistical layer = optimizedIDW This new GA layer (optimizedIDW) with have an optimized power value for the dataset and field supplied in #3 and to convert it to raster use GALayerToGrid geoprocessing tool. Regards Steve

What happens if you inser a gp.BuildRasterAttributeTable_management(Temp_Raster) before the Lookup? The Temp_Raster might be too large for automatic table building (see http://support.esri.com/en/knowledgebase/techarticles/detail/27056 for limits) Steve

The mask is applied post interpolation so it'll not have the same effect as a barrier. Try to reduce the number of vertices in your barrier. See tools in the Generalization toolset can be used to create a new feature class by smoothing or deleting some of these features. Steve

Patrick Yes it can take a long time. The barrier implementation is using a line of sight approach. I.e. from the location where you want a value it'll "look" to see which points are "visible" and then use only those. It'll also depend on the complexity of the barrier featureclass, i.e. how many vertices and on the number of input points and then on the number of output cells. You should, however, first test how long it takes without the barrier. Steve

- I guess you are in a geographic coordinate system (i.e degrees decimal), not a good idea as 1 degree longtitude <> 1 degree latitude. - default size cell produces an output raster of roughly 250 columns and 250 rows - with you changing the cell size to 1 will mean that your output raster will have roughly 1 row and 1 column - I notice that you are in a comma locale and using ArcGIS10, have you installed the latest Service Pack (SP5)? - 3.4e38 is a NoData value, which basically means that your output raster is empty. Regards Steve

‎01-10-2013

What is the default cell size that shows up in the dialog after you enter the ga layer into the control? Please also state clearly what happens when you run the tool. I'm not sure what you mean by "I have a similar problem." Thanks Steve

‎01-09-2013

Such features are available through the geoprocessing environment. I.e. when using GP tools. The Wizard, however, does not honor these environment settings. You could, however, use the layer that you created in the GALayerToGrid tool and specify an output extent in the environment and your output raster will then have this new extent. Steve
