This maar is unique by the fact that it displays a large number and variety of structures associated with active deformation and high albedo sediments.
We used a small Unmanned Aerial Vehicle (quadcopter) and a consumer grade camera to develop both a DSM and an orthophoto at a resolution of 4.7 cm through the use of Structure from Motion (SfM) algorithms from PhotoScan Pro, a commercially available software.
Using the coordinates of 31 Ground Control Points measured with an RTK GPS, the residuals of the DSM had an RMSE=3.3 cm and a m...
