Hello! I want to show the counts for graduated color quantities that have been normalized (weight/area (hectare)). I want to know how many areas fall within each weight range. Does anyone know an easy way to do this? It's possible with the "categories," but those ranges would be different because they're not normalized. Any help would be much appreciated! Thanks, Lana

Hi Everyone, I'm trying to download my File Geodatabase in Survey123, and it always fails to download. I've looked at some other links that others have written about solving this issue, but haven't had any success as of yet. Can anyone walk me through a solution? Thanks in advance! Lana

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

Hi Xander, Thanks so much for your reply. I've attached a small and large scale image of the hillshade, so that you can see a close-up of the area where the stair step terracing appears in the viewshed. Thanks, Lana

Hi Yuri, Thanks so much for your response! I've attached 3 screenshots of the raster properties dialogue for you to look at. Is there anything else that I can send you? Again, thanks for your help! Lana

Hi, I was hoping that someone might assist me with understanding what the problem is with the viewshed analysis I did. I hope the jpg I attached below worked. In the image, you can see that at this scale the visible areas of the viewshed appear as lines similar to terracing, but the terrain is not actually like that. Does anyone have any idea why it would appear this way? Is it a problem with the resolution of the dem? (It's a 10 meter dem). Thanks for your help!

Hi Everyone, I was hoping that someone might be able to help me. I am trying to do a viewshed analysis using archaeological data, but the problem is that I want to include hypothetical heights for the fortification walls around a settlement, so that my viewshed analysis takes this into account. How do I go about adding these heights to my dem? Thanks so much for your help!

Hi Everyone, I was wondering if anyone knows where I can find a good DEM for Turkey, the Karia region i.e. Mugla, Datca. I'm an archaeologist working at a harbour site in Datca, and the DEMs I've found so far are poor resolution and at a too small scale, particularly when I need it for a very small geographical area. Thanks for your help, Lana
