LiDAR has a 99.9% uptime service level objective; excluding planned outages, maintenance windows and unavoidable events.
Elevation data is essential for a broad range of applications: flood risk management, ortho rectification, emergency managementt, damage assessment, view shed analysis, natural resource conservation management, just to name a few. LiDAR, stands for Light Detection And Ranging and is currently the primary collection method for elevation data. The LiDAR initiative provides multiple options for users interested in exploring Maryland's elevation data.
Elevation data for the entire state of Maryland is now available for download. Learn more about available LiDAR collections, download formats, typical LiDAR users and respective tutorials. Check back often as we continue to add more LiDAR resources for download.
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.
Users can display and interact with the elevation products through ArcGIS Online (AGOL). AGOL maps have been pre-populated with core and derivative products in both county and statewide extents.
