Enhanced Cut-and-Fill Mapping added in Drone Surveying Package

Virtual Surveyor has added cut-and-fill mapping capabilities to Version 7.0 of its popular drone surveying package. The new functionality enables users to quickly perform volume difference calculations and generate cut-and-fill maps from drone images captured on two or more different dates. The Virtual Surveyor package enables professional surveyors to generate accurate topographic end products from drone data five times faster than traditional field work, bridging the gap between UAV photogrammetric processing software and engineering design packages. The enhanced cut-and-fill functions are part of a new feature in Virtual Surveyor 7.0 called Terrain States. This allows the user to create separate Terrain States for surface models generated from UAV images captured over the same area on different dates. The user can easily delineate and delete objects, such as bulldozers or excavators, that appear in a single surface model. These changes are saved in only one Terrain State so they do not cause volume measurement errors when a surface model is subtracted from another. www.virtual-surveyor.com.
