Elevation data is essential for a broad range of applications: flood risk management, ortho rectification, emergency management, damage assessment, viewshed analysis, natural resource conservation mangement, 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.
