My problem is that i have drone images in WGS 84 and their height is about 180 meters. During recording I used DJI app for calibrating compass and IMU and GCP points ( which are in HTRS 96/TM c.s but i converted them to WGS 84). GCP height ( Z coordinate) is around 112 meters. After i added images in Drone2Map, I could not add my GCP points and i got message that my control spatial reference is wrong. I tried this:&nbsp;<A href="https://community.esri.com/t5/imagery-and-remote-sensing-questions/drone2map-how-to-adjust-image-altitude-in-exif/td-p/272941," target="_blank" rel="noopener">https://community.esri.com/t5/imagery-and-remote-sensing-questions/drone2map-how-to-adjust-image-altitude-in-exif/td-p/272941,</A>&nbsp;but message is same again. In Site Scan I set EGM96 geoid, and height, DEM of my models is correct.&nbsp;</P> <P>Sorry for bad english and if i did not specify my problem!</P> <P>&nbsp;</P> Sun, 14 Nov 2021 15:16:40 GMT https://community.esri.com/t5/site-scan-manager-questions/drone2map-control-spatial-reference/m-p/1080975#M42 mpgeof24 2021-11-14T15:16:40Z https://community.esri.com/t5/site-scan-manager-questions/drone2map-control-spatial-reference/m-p/1081593#M43 <P>You do not need to follow that old post (from May 2018) to adjust altitudes in the EXIF metadata.&nbsp; Drone2Map includes an altitude adjustment, and if you use GCPs with the correct spatial reference, image height is adjusted automatically.&nbsp;</P><P>You said that you converted GCPs to WGS84 - note that GCPs must be in a projected coordinate system; Lat/Long is not supported - but you should've seen this error message if you tried to use Lat/Long&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="CodyBenkelman_0-1626981721943.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/19167i1F9F8328586002B6/image-size/medium?v=v2&amp;px=400" role="button" title="CodyBenkelman_0-1626981721943.png" alt="CodyBenkelman_0-1626981721943.png" /></span></P><P>Could you try your GCPs in&nbsp;<SPAN>HTRS 96/TM?</SPAN></P><P>Cody B</P><P>&nbsp;</P> Thu, 22 Jul 2021 19:23:08 GMT https://community.esri.com/t5/site-scan-manager-questions/drone2map-control-spatial-reference/m-p/1081593#M43 CodyBenkelman 2021-07-22T19:23:08Z
