DObrý den,
chtěl bych se zeptat, jak nastavit systém JTSK pro spracování dat z laserového skenování. A také jaký je správný formát souřadnic pro import vlícovacích bodů.
Hi,
in the first step it is a good habit to set the project and output coordinate system to the JTSK. For that use 5514 system which is using the negative coordinates. The settings can be find under WORKFLOW/Application/Settings/Coordinate systems
Then you can import your laser scans. In this steps it depends, if they are already georeferenced in JTSK or in local coordinate system. Or if they are already registered.
If they are registered and georeferenced I would use these settings:
and you should see the scanner’s position on the right place in the map view.
If the scans are not georeferenced and registered, then you can set these settings:
and you will be able to georeference the cloud using the GCPs.
For 5514 system use negative coordinates and the GCP file could look like this:
where you have name, Y coordinate, X coordinate and Z coordinate.
But for importing such file you will need to set it as
because of the difference in the orientation of the JTSK and application’s coordinate systems. After import you should see the GCPs on the correct position in the map view.
Also, make sure that the GCP’s are visible on at least two laser scans, as the placing of the control points there is similar to the image’s way.
