Hi Xander and Yuri,
Thanks for the information. Xander, I got this dem from a colleague, so I'm not sure if it was created from contours/TIN, but I will ask. The dem is definitely much larger than my area of interest, which has been a persistent problem for me. I am working on a small archaeological site (c. 45 hectares) in the area of Datca in Turkey, so the scale of data in the dem is much too small for what I need and, as a result, the elevations are not accurate. I've been trying to find a way to get/create a large scale map of the area I need, but I haven't had much luck so far. I have a contour file from a colleague, but sadly it doesn't include any elevations for the contours. I've also tried Google Earth, but can't seem to get any good results from it...
Yuri, I tried the 'Focal Statistics' tool, and it helped quite a bit, as you can see from the image below, but the terracing still appears.
Thanks again for all your help! If you think of any other ideas, please let me know.
Have a great day!
Best,
Lana
