    I've been searching the forum and read all the manuals avalible for Context Capture Master and the process of aerotriangulation and productions of orthophotos. But I'm still uncertain on how the process should be conducted in order to achive best result…

    I'm desperately searching for a page I've recently seen on the forum (or was it the Wiki?), describing the maths and process on how to determine a good distance between GCP;s on a large land survey project. - Is there anyone out there who know what…

    For our ContextCapture projects we have two customers. One customer needs Nad83(2011) NCSP NAVD88 Geoid 18 (xyz units us survey foot), the other customer needs Local Space Rectangular. The difference between the two SRS's is normally a scale factor. Knowing…

  • VLP-16 LIDAR with KAARTA integration into Context Capture

    My school is undergoing a campus modeling project and we only have a cheap VLP-16 LIDAR puck scanner that we have been able to use and process through KAARTA. Because of the minimalistic setup, there is no GPS on the unit and no geographical reference…

  • Why does my focal length change for the same camera in different photogroup?

    I'm using Sony A7R II with 28mm lens and I'm curious why my focal length change slightly? it's a prime lens and manufacturer spec says it's 28mm and the aero-triangulation optimized the focal length in the range of 27.13mm - 27.20mm for different photogroups…

    Hallo! I am having big problems with importing Control Points in ContextCapture via Control Points Editor. Please check my Attached TXT file where I have GCPs from Local Survey team. Software does not want to import them. I have tried several formats…

    Hi! I'm testing the accuracy of the photogrammetry process. So I use GCP and check point (CP). When I use only GCP the aerial triangulation's error is not relevant and the result is good but when i use GCP and CP the CP's error is higher than GCP's…
