So I have a lovely coloured, shaded ortho with the shading representing elevation, created under the Visualization menu. How do I export that image as a full resolution JPEG for the client? I see no Export or similar options in the UI.
Your processed outputs should be in a folder similar to this DSM: your_project\3_dsm_ortho\dsm\your_project_dsm.tif
You can access to that folder above either manually navigating to it or under Process tab then Open Results folder.
They should be in a .tif format but you could use either GDAL or QGIS to convert it to a JPEG.
