The best available elevation data is maintained in a centralized location and provides a variety of core and derivative services in both county and statewide extents. Available services include digital elevation model (DEM) in feet and meters, shaded relief, slope, aspect and hill shade.
The Maryland Topography Viewer is a web application that allows users to view and interact with the elevation services hosted on the Maryland LiDAR server. Users can view, query and more on desktop and mobile devices.
