Gps pathfinder office new license code3/17/2024 The older version of Drone2Map had a "Ellipsoid" and "Height above ellipsoid" option, but with the June updated and Advanced License that is no longer options. I processed them through CSRS-PPP, and I'm actually struggling with this part. So if anyone has a better/clearer explanation for this, I would appreciate it! Which I feel makes sense, my only question is: Online I've read the "height is in reference to the ellipsoid" because of GPS and "height is relative to the ground" meaning where you took off was considered "0 elevation". I've also been experimenting with this, as I input 197ft as my flight altitude, and my altitude from Image Table goes from ~22 to ~60m. I'm using a DJI Drone, so I also know that the altitude needs to be adjusted in Drone2Map. Where do the image geotag coordinates come from?įrom what I've read online EXIF metadata. I'd really appreciate talking this through with someone. Rubber sheeting of the orthomosaic does not correct all of the interior. Still in the interior we can have some unadjusted areas with 6 to as much as 12 feet of error. The coordinates at the edges of the boundary were confirmed and the orthomosaic adjusted. Trimble readings were use to confirm and improve the accuracy of the 3 foot commercial data. We continued to improve accuracy of the orthosmosaic. As we moved from the control points to the edges of the D2M orthomosaic, ground errors of approximately 21 feet were observed. Later comparison with 3 foot commerical data, confirmed that the GCP'sData at the control points were later confirmed to be within 3 feet. The Ground Control point coordinates, WGS 1984, were collected, with a Trimble geoxplorer 6000 and the data post processed to an accuracy of between 15-50 cm. Control point data, including Z values, were input using a table. We flew an 80% overlap, crisscrossing survey with about 8 control points. Next, the further the distance from a control point, the more inaccurate orthomosaic. Our first lesson was unless you have a good density of control, spatial distortion can be present at the control point even if you use 4 pix per control point. The result was evaluated by comparing with a commerical basemap with an accuracy of 3 feet.
