Maximum-Uses the maximum z-value found in the sketch vertices to define a flat base surface at the maximum elevation.Minimum-Uses the minimum z-value found in the sketch vertices to define a flat base surface at the minimum elevation.Interpolate-Uses the z-value at each vertex in your sketch to interpolate a base surface for the volume calculation.Constant-A user defined value that defines a flat base surface.The reference surface-called the base surface-can be created using any of the following Base Surface options: The volume measurement is calculated from a reference surface determined by the polygon delineating the object you want to measure. If you have a choice of elevation surface types for your area of interest, it is recommended that you use a DSM, which best represents the elevation of features above the ground. You can measure the volume of objects in a DSM, DTM, DEM, or other elevation dataset using the Volume tool in the Mensuration gallery. Draw a polygon around the feature to calculate and display cut and fill volumes in the map, the Results pane, and the measurement report. Volume of features can be measured from any georeferenced raster dataset, mosaic dataset, or image serviceĬomprised of an elevation surface such as a digital surface model (DSM), digital terrain model (DTM), or digital elevation model (DEM).
