Is this your export web map service? If soRepublishe it with info level warnings and make sure its synchronous and you have added the get map template info result. Completely remove the widget, save, exit. Restart web editor and add the widget again. ... View more

Is this a default tool or one of your own? Perhaps resetting the normal.mxt might solve it. ... View more

Exactly, I would test this with another script tool with only a feature and the field map and see if you can grab a class attribute or type. Something like fieldmap = arcpy.GetParameter(1) property = fieldmap.inputFieldCount arcpy.AddMessage(property) ... View more

Would it be a field mapping object you would call as arcpy.GetParameter()? Good luck, field mapping objects give me nightmares. ... View more

Raster calculator the difference between the true DEM and your interpolated one, square it, the run something like zonal stats as table to grab the mean, then take the root. here's some code. I've not tested it. may have to save the raster objects as interim data. let me know if it doesn't work and i'll amend the code. import arcpy #path to your original accurate DEM - make sure path is enclosed by r' ' original_dem = r'c:\\myproject\mygeodatabase\originalDEM' #change the below paths to your interpolated DEM paths # - make sure path is enclosed by r' ' #interpolated DEM 1 interp_dem1 = r'c:\\myproject\mygeodatabase\interpDEM1' #interpolated DEM 2 interp_dem2 = r'c:\\myproject\mygeodatabase\interpDEM2' #interpolated DEM 3 interp_dem3 = r'c:\\myproject\mygeodatabase\interpDEM3' #interpolated DEM 4 interp_dem4 = r'c:\\myproject\mygeodatabase\interpDEM4' #interpolated DEM 5 interp_dem5 = r'c:\\myproject\mygeodatabase\interpDEM5' #make a list of the interpolated DEM paths interp_dem_list = [interp_dem1, interp_dem2, interp_dem3, interp_dem4, interp_dem5] #turn the original DEM into a raster object, #iterate through the list, turn paths into raster objects to perform #raster algebra on them, output raster cell values will be #(interp_dem - original_dem) ^ 2 original_dem_rasobj = arcpy.Raster(original_dem) #set a counter to label result with iteration number iteration_counter = 1 for interp_dem_path in interp_dem_list: ras_object = arcpy.Raster(interp_dem_path) ras_diff = (ras_object - original_dem_rasobj) ** 2 #get the mean of this raster ras_stats = arcpy.CalculateStatistics_management(ras_diff) ras_prop = arcpy.GetRasterProperties_management(ras_stats, "MEAN") ras_mean = ras_prop.getOutput(0) rmse = float(ras_mean) ** 0.5 #print out the rmse in the python window print("RMSE of Interpolated DEM Raster " + str(iteration_counter) + " = " + str(rmse)) #add 1 to the iteration counter iteration_counter += 1 print("Processing Complete") ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

Hi Stephen, There is often alot of confusion with tables which hold lat long figures. A table can exist but hold no geospatial location. Changing these values in the table will not create  or update the location of points. You need to add the table as xy data, then save it as a feature class or shapefile. Search for adding xy data in the help files or Google and you will find a trove of info. ... View more
