Accessing the Data
The second generation of Minnesota's lidar data and derivatives may be accessed from various sources.
- (Coming Soon!) MnTOPO 2: a web application to interact with the data
- User Guide to Adding Second Generation Lidar Resources to Desktop Mapping Applications
- STAC Catalog and VRT products may not function in ArcGIS Pro versions 3.5 or older.
- SpatioTemporal Asset Catalog (STAC)
- Browse and access the Minnesota digital elevation model (DEM) datasets and metadata
- Due to the size of the datasets, they should not be downloaded directly. Instead, users should access the data in their preferred GIS client and clip to the desired area of interest for analysis, if necessary
- To browse the STAC catalog and access datasets within your preferred GIS client, please copy the following URL: https://stac.gisdata.mn.gov/
- Virtual Raster (VRT)
- The VRT can be accessed in your preferred GIS client allowing detailed analysis and visualization of the lidar data
- Copy the following URL to add the VRT to your GIS software: https://g46prsaddst01.blob.core.windows.net/mntopo/dem_100k/2nd_Generation_Seamless_Lidar_DEM.vrt
- Minnesota Geospatial Commons
- Minnesota lidar work unit resource information and metadata can be found on the Geospatial Commons website under the "elevation" category
- Information about the flight swaths followed during the collection of the statewide lidar data is also available through the Commons as an Esri Feature Service
- Data may also be available through the following federal resources:
- USGS National Map
- See also the related National Map Downloader
- Please view additional resources below for further documentation
- USGS Lidar Explorer Map
- NOAA Data Access Viewer
- Data can be placed in cart for download and reprojected to desired output; the lidar deliverable can include contours set to desired interval
Statewide Datasets and Derivatives
The following lidar datasets and derivatives are currently available from the State of Minnesota. As more datasets become available they will be listed here. To retrieve original (unblended) data by specific work unit or lidar acquisition block, please refer to the Areas Covered section below.
| Dataset | Access | Commons Resource |
| Seamless (Blended) 0.5 meter DEM | STAC, VRT, Image Service |  |
| Flight swaths | Feature Service, Map Service | |
Areas Covered
In 2021-2024, lidar data was collected for the entire state of Minnesota. The data is organized into blocks and work units, with each block covering a large area and each work unit covering a smaller area within the block. Data from these collections has been blended to create the seamless statewide datasets. The following table lists the lidar acquisition blocks and work units, along with their geographic extents, collection dates, and the associated metadata provided by the vendors responsible for collection of the data. This data is provided in the original, unblended format, and may be appropriate for analysis that occurs completely within the given work unit.
