Bug Reports / Re: CL_invalid_value (-30) at line 36

I had such errors when my graphic card was getting hot. I turned on the fan and everything works now.

Hello, i did two tests:

1- i compared two GNSS, one native in EPSG31700 and the other GNSS in EPSG4326 then transformed in EPSG31700 using Agisoft. The results are shown in table above. 2.11 m to east agisoft transform.

2- I took the same EPSG4326 measurements from EMLID  GNSS receiver and transformed it using an online tool to convert to EPSG31700. The results are the same, 2,12 m offset against Agisoft transform on X and 39 cm on Z. Y is the same in Agisoft and TransLT.

See files attached.

I noticed a more than 2 m shift on X in my final EPSG31700 (Stereografic 1970) after converting measured control points with Metashape V1.5.2 build 7838.
I also noticed 20 cm on Z difference.
I checked with a GNSS who offers the results in Stereo70 and i got about 2.11 m offset between it and Agisoft transform of WGS84 to Stereo70/EPSG31700.
I double checked with online app who transform WGS Lat& Long to Stereo, link below, and i got exactly 2.12 m shift on West
You may use the app called TransDatRO to check the transform.
Note than ETRS89 and WGS84 have the same Lat, Long and height for Romania.
Picture below shows the difference between measurements of the same points with different GNSS, straight in Stereo70 and transformed through Agisoftt Metashape.

ps. i own a student licence of Metashape Agisoft.
