Orthoplane is an orthorectified image of any planar object. Orthoplane can be extracted from building facades or such as in this case vertical rockfaces with the help of drone imagery
This type of rectified rockface images can be extremely useful for geologists, geomorphologists, risk assessment managers,… as it allows high resolution visualization to locations that are usually difficult to reach
For this model, a DJi Phantom3 drone and Pix4D software were used to scan a quartzite rockface over Evolène, Valais, Switzerland
