Volumetric analysis using a mini-plane DSM Client: Natural Resources Wales Exegesis undertook an aerial survey of a site and orthorectified and mosaicked the imagery to create a single image. We also generate a digital surface model, which was compared against lidar data to give the change in height. We then determined the volume of additional material within patches identified from the aerial photography. ... read more November 2013.
