The Feather River releases are at 4,000 cubic feet per second (cfs). To better understand how mapping works, it is often easier to look at it within the context of how the resulting maps are used. The mesh is generated by creating surfaces connecting the points in the point cloud. The Digital Surface Model (DSM) is a representation of the elevation or terrain of the survey area as well as above-ground features like buildings, towers . In photogrammetry, a drone captures a large number of high-resolution photos over an area. Drone2Map also enables the creation of DSM orthomosaics with sharp building edges and all aboveground features in their correct horizontal location. Will you need to fly over people or across a busy road? [Updated 2021]. Orthorectified imagery differs from standard aerial photographs in the way that it visualizes perspective. It is useful for just about any type of map output and runs data processing locally. Since its impossible to accurately map a bench face from 100 feet above the face, the ability to autonomously fly a drone at different elevations while mapping a mine site or a bench face is a critical skill for the modern mining professional. This vertical datum takes into account changes in elevation or orthometric height due to terrain and significantly departs from the ellipsoid Earth model.
