| • orthoimage creation from, e.g., terrestrial point cloud data |
| • distance measurements in the output image |
| • point cloud visualization |

| Features |
|---|
| • orthoimage (orthorectified raster) creation from all points detected within a user specified range to a profile line |
| • profile line is interactively digitized in a Map View |
| • AOI is aligned left or right to the profile line, or centered on the profile line |
| • gridding of a user specified attribute |
| • additional output: depth image (range) |
| Application |
|---|
| • orthoimage creation from, e.g., terrestrial point cloud data |
| • distance measurements in the output image |
