The DEM is derived by photogrammetry from the 2012 - 13 rural aerial surveys. Horizontal and vertical accuracy is +/-0.8m (1 standard deviation) in clear open areas. Elevations are for the visible land surface, not the ground level. For example trees will show as elevated mounds, since the DEM will present the tops of the trees. Data is provided “as-is” without warranty of accuracy or suitability of use”
