Hi everyone, just wondering if someone could help.
I carried out my first flight yesterday over a earth works site and my intention is to create a 3d point cloud of the site for volumes etc. I took around 460 photos with the dji phantom 4 pro, and I have ran it through pix4d desktop. Firstly I noticed all the altitude values were negative. To solve this I just exported a CSV to excel made the values positive, and brought it back in. Is this appropriate or will this mess with the accuracy of the data processing?
Secondly, I wanted to select a different coordinate system from googles WGS 84 system which is giving me lat and long to NZGD Mt Eden 2000 which will give me X,Y. However when I do this none of the coordinates on the photos translate over to the selected system and when I run the initial processing (step 1) it totally fails. Does the software not have these projections and translations built into it? Any advice on these steps would be hugely helpful
