Is it possible to calculate oblique photo scale by given vertical photo scale ? I mean is there any kind formula relation between them or maybe is it possible to calculate rough approximation of oblique scale ?
Using GRASS GIS (OSGEO)
Ortho-rectification of oblique photographs
In projected location:
get approximate camera position: d.where/d.what.rast: EAST: NORTH: 664194.71461534 5104463.03343466 height: 450 Pitch: 20 Roll: 0 Yaw (against north): -45
