Trouble with loading .asc file

Post by stanjohnsuab »

Dear friends, sorry I have noob questions here. I have two .csv files which i have collected using EMlid GNSS.
I tried to open by: File --> Open: set the header X Y Z --> click "Apply all" and then nothing is on display.
Please help thanks.

I don't think it's actually 'nothing', but more probably a long 1D line of points (you may see it by rotation the view).

Your X and Y coordinates seem to be angular coordinates,while your Z coordinate seems to be 'linear'. Therefore the scales (and shape) don't match, and the cloud looks weird.

CC doesn't handle angular coordinates (or 'geographic coordinate system') but only euclidean coordinates (or 'projected coordinate system')

Daniel, Thank you for your reply.

Ya, I managed to solved the problem by converting it to LAS format (UTM coordinate) using ArcMap.
