I seem to be getting elevation values about 3 times as large using the ESRI import as compared to the USGS import. It's almost as if the ESRI values are correct at the source (wherever that is) but with a unit of meters. Is there some metric/imperial conversion taking place or a setting that needs to be changed?
I tested this Topo Import Tool, and had a similar issue; I don't have an ESRI license to compare it to, but I was testing this in an area near another project, so I had a good idea of what the elevations should be (400-700 feet range), but was getting contours in the 3000s. I started comparing the contours to how the topography should visualize, and they didn't line up; even if there were a vertical conversion issue, it should still look like the same topography (I was looking at a bluff against a river floodplain, so should be pretty easy to differentiate). Instead, I think it was pulling in some mountainous terrain that does not exist in Missouri; not sure where it came from. I also tried the SRTM option, and it pulled in similar contour values to the USGS data, but didn't look like either terrain. I'm guessing there is some error in how ORD is translating the metadata from those sites and converting it to the user-defined coordinate system.
Hello, if you can share some examples that would be great so I can investigate this issue. You can upload any data here: https://bentley.sharefile.com/r-r1ee37a0ca8d6441ca5a708874e9f9ef9
Thanks Marc, I'm uploading a new test file now. I didn't keep my original, since it didn't provide the data I needed, but ran through it with a new 3D file, no workspace, following the process discussed in the OpenSite video on using this tool (https://communities.bentley.com/products/road___site_design/w/road_and_site_design__wiki/52460/topo-import-using-usgs).
Both the USGS and SRTM provided contours in the 3000s, and looked like completely different terrains than the background image of the Missouri River, floodplain, and bluff. This is the same general area I tested before, elevations should be around 400-700 feet.
