I attached some screenshots: DTM, points, slope, resulting buffer ... View more

well, my dtm values are High : 927,206, Low : -17,8801. I assume that with these values it should appear different (which means like Xander's pic). I tried another time using some points placed in a more hilly area, yet the circle buffer zones are stil "flat" without any surface adapting.  ... View more

Ok, I will try to save and reboot the program. Anyway, the obtained raster is not like in the Xander's picture, it is "flat" as I had done it with the buffer wizard ... View more

Thank you for replying me.... So I used the Xander's code in my python, it gave me the buffer zones (max dist. 3000) yet it showed an error: "Runtime error  Traceback (most recent call last):   File "<string>", line 72, in <module>   File "c:\program files (x86)\arcgis\desktop10.3\arcpy\arcpy\management.py", line 3246, in AddField     raise e ExecuteError: ERROR 000464: Cannot get exclusive schema lock.  Either being edited or in use by another application.

Sorry, it worked yet with a strange result ... View more

Thank you for your suggestion!!! I tried using the intervals at 15, 30, 45, 60, 75, 90 and it worked, at least the shp appeared into the layer table of contents yet it didn't show up in the data frame.  Sorry for bothering you Thanks Roberto ... View more

Sorry, it is not clear to me.... So, I have to use the contour tool setting intervals like "10, 20, 30, 50", did I understand well? Anyway, I need the lines to estimate graphically the walking time lapse. Roberto ... View more

So, I stored it in a geodatabase and put your value.... It worked! Thank you!!! But now I need to work with low contour values, because for it is the time lapse that someone could take to cross the landscape...so, should I resize the raster or there is another way? Roberto ... View more

the raster has as max "High : 1,94202e+006" and min "Low : 0", while the output going to a shapefile Roberto ... View more

hi Steve, the interval that I used was 15, but also with 10 I had the same problem.  Yes, it is not the first time that I gained the slope from this DTM and always it worked.  Thanks Roberto ... View more

So the path distance worked, but I still have problem (that it is the hardest now) with the contour tool, since when I launch after a while ArcGIS shuts down or crashes or blocks. So I tried to attached here my files, but without success... If it is possible, may I have your email in order to send you? Thank your for your patience and time. Regards Roberto ... View more

Thank you for the reply Xander, I tried to make shorter the path and putting the data bulk into a unique geodatabase but I still continue to have problem only using the path distance tool. It sounds strange because I used the same DTM for cost distance, euclidean distance, cost path, slope, viewshed tools with reasonable results. Moreover, although the DTM was obtained from a merging, all the single DTM tiles come from an official site. Could it be the use of the Tobler's function table (as explained both in the web page link and in the academia.edu link)? ... View more

Dear Dan, Thank you for your suggestions... I observed the monitoring system and actually the RAM involved it was almost the 70% using the contour tool, yet it stopped at the 6% so I thing it was a memory problem. Therefore, I tried to clip my DTM and I followed the steps as in the guideline (ArcGIS Tutorial: Tobler's Hiking Function | Kaitlin Hakanson - Academia.edu). It worked correctly up to the point 4, yet when I used the contour tool it didn't work again (it reached the 3/4%) then I launched the tool a second and a third times but it failed directly. So, I guess that I should attempt to do it in PRO (as you said) or maybe to expand my RAM, just because the file clipped or not seem to work for the other tools. Thanks Regards Roberto ... View more

Actually it is a question... So, the DTM (8x8 cell and it is a merging result form other form the same source) comes from the Apulia Region website (Italy), I used it for all my process in Arcmap. But I don't know now it didn't work... I used the DTM for applying the Tobler's function as described here: Week 9 - Anisotropic cost surfaces and Least-cost paths | www.MapAspects.org . So it worked up to the Path Distance (part B, step2), but just once. So I tried to use another method (ArcGIS Tutorial: Tobler's Hiking Function | Kaitlin Hakanson - Academia.edu ), but in this case the DTM didn't work at all. So, just as attempt I used the Slope (generated from the DTM), it worked up to the point 4, because when I tried to use the contour tool Arcmap crashed or shutted down directly. The file are stored in a separated folder in the second HD subdivision, that it is not that one in which was installed the program and where it is the default database (but since now I worked like this without problem), in my laptop (the only machine with which I used to work). I attached some specs on my DTM and PC (you have to consider that the HD subdivision in which is installed ArcGIS has free 95.4 GB on 372GB (276GB used); while the second one 487 GB free on 537 GB (49.6 GB used). I hope that in this way it is more clear. Thank you in advance. Regards Roberto ... View more
