Thanks for the Mapping Centre link on bump maps... Interesting and this need some experiments, time permitting. The effect I am looking for is a sort of subtle shading such as the NG map sample attached. Perhaps tweaking the luminosity of the hillshading layer produced in the Referenced Modaic Dataset could help to produce a similar style... ... View more

Thanks. Yes it is too much. I am looking for subtle shading such as the IGN map attached... A hillshading just to accentuate the relief and overlay other layers... If this makes sense. Currently, I experimented the Hillshading function in a Referenced Raster Mosaic with a z-factor = 0.00001 Perhaps, this is the wrong function to use? ... View more

Thank you for asking about the time.strptime function in my script... And I appreciated the blog post. Unfortunately, I cannot find out which file (or anything else) is missing on the other machines on which I wish to run the script. The PythonWin gives me the following paths, but it doesn't tell me from which file the time.strptime is coming from! For the time being, I intend to "suspend" any call to time.strptime even if it makes the script less efficient. PythonWin 2.7.3 (default, Apr 10 2012, 23:31:26) [MSC v.1500 32 bit (Intel)] on win32.

The Python looks installed correctly on the other machine with a C:\Python27\ArcGIS10.2\ folder containing the libraries and all the stuff... It looks like. This is why I was suspecting the file to which the time module references might be not in the right place! Or there is a variable to set in order to indicate explicitly where to ook for Python libraries, modules... In addition to find out the file the time module references to, where is it possible to check/set the path and other variable for Python? Thanks ... View more

It is already a line at the beginning of the script: # Import system modules import sys, string, os, arcpy, time But the time module probably references to a file which is not on the other machine, I imagine. It works on mine... ... View more

Hi, The Raster Catalog is in a File GDB v10.2. With a Mosaic Dataset, it takes just a few minutes to run the script versus a few hours with the Raster Catalog. However, I would prefer to use Raster Catalog because it can manage the rasters within the File GDB and compress the rasters smartly. The Mosaic Dataset just point to the rasters on disk... The error I receive is: <function GetMessages at 0x1ACABF70> Completed script RasterValuesToPointsCATALOG... Succeeded at Tue Dec 22 11:44:46 2015 (Elapsed Time: 1.48 seconds) when the script tries: arcpy.gp.ExtractValuesToPoints(fc, raster, fc_tmp) This is the reason why I suspect the rasters object genereted with the Walk functions not containing the proper raster... ...

Hi, The ListDatasets function works very well to run through a RasterCatalog. It took 3h58min to extract elevation from 1320 tiled DEMs... Now, I would like to test the Walk function in order to see if the processing would be faster because the Data Access module is supposed to access data much faster according to ESRI documentation. However, _, _, rasters = next(arcpy.da.Walk(rasCatalog)) for raster in rasters:      arcpy.gp.ExtractValuesToPoints(fc, raster, fc_tmp) did not work with workspace set a the Raster Catalog path... And I have to admit that I am not familiar with the Data Access module syntax! ... View more

Thanks Your syntax does work for listing the rasters in the Raster Catalog, but now I cannot go further: for raster in rasters:     arcpy.gp.ExtractValuesToPoints(fc, raster, fc_tmp) ...because I would imagine that rasters contains only string and not Raster object. Any guess? ... View more

Thanks. It works very well. As long as variable id is a number (integer or float) and not a string. Also, I used the former 9.3 syntax because this script was initially made at that time and I haven't upgraded the code to arcpy... ... View more
