Height Modernization (ILHMP): LiDAR Data [Illinois]
Description
***New****  Download LiDAR Data thru our new Web Application Viewer.  The Viewer allows users to zoom into an area of interest and then simply select LAS tiles to download.  *****  Historically, Digital Elevation Model (DEM) data for Illinois have been mainly based on 5- to 10-foot contour data. Large-scale, digital topographic maps are most common; many data resources contain elevation information acquired in the 1920s and 1930s. DEM data collections are now being developed based on data with a contour resolution of 2 feet to 6 inches. A comparison between older data and newer high-resolution data shows remarkable improvement in recorded detail. ILHMP has established data sharing agreements to archive and distribute elevation data for select Illinois counties. Data have been acquired using Light Detection And Ranging (LiDAR) technology, in compliance with different contract specifications. Data are offered as originally deliver LAS tile or as the derivative product of DEM/DTM or DSM. Some helpful links: LiDAR Base Specifications 2024 rev.
