Hello, good summary!

Can you also include the appendix that is indicated on PowerPoint page 31, please?

Is "Appendix E: Photo Triangulation in Depth"


Thank you very much

Appendix E is available in the help file that is delivered with ISAT, and also in the real time documentation for ISAT on the web at  This appendix is too large to include directly in the PowerPoint, so we only mention in the PowerPoint that this additional source of information is available in the help file.


Hope that helps, thanks for the input!

I have a question I hope you can help with. 


Using ISAT we have computed an AT result. 


We have applied all the correct camera parameters, imported post processed GNSS/IMU data and imported ground control points positioned at the edge of the blocks with one or two in the centre of the block. Despite good residuals when the St project is using to create the orthophoto, the operator is experiencing height errors in the region of 3 metres.


Any idea what could be causing this?


Many thanks
