LiDAR Elevation Data for Minnesota
LiDAR ("Light Detection and Ranging")
is an active remote sensing technology that uses laser light to detect and measure
surface features on the earth. LiDAR-derived high-resolution elevation
data products are available for all of Minnesota.
- Hydrographic Position
Index Technical Report: Combining LiDAR-derived DEM
analysis, raster classification and color symbology for pseudo-3D terrain
visualization to enhance hydrography interpretation on the DEM landscape,

LiDAR data, wins Esri Climate Resilience App Challenge award
MnTOPO: A web application for viewing, printing and
downloading high-resolution elevation data for Minnesota collected using LiDAR
- View terrain data and contour lines, choose from several basemaps, view
flight lines and metadata
- Create, save and print a map
- Find the elevation of a point and draw elevation profiles
- Download LiDAR data by drawing a polygon around your area of interest
- Select only the layers you need
- Choose from several formats
- Tiles in most formats will be mosaicked for the download
- Tip sheet:
If you get a loading error with MnTOPO, it's likely caused by a
"Compatibility View" setting in Internet Explorer browser v11 which is
- Folder names and
organization have been changing, so some of the paths given in the readme files
need updating. The readmes will be updated once the names and organization
stabilize - please let us know (
if you are having trouble finding anything.
- Contents and
filesizes of LiDAR
- This table summarizes the derived products found in each
county geodatabase since not all counties are identical (e.g., not all
counties have a building footprint layer)
- Filesizes for the county geodatabases are included since the
filesizes no longer display on the FTP site.
- If you haven't used this site or LiDAR data before, see the help files.
- Download problems:
- Many of the data files are huge and
should be downloaded with an FTP client rather than a browser.
- No username or password is needed to download from
MnGeo's FTP site. For unknown reasons, sometimes the Internet
Explorer (IE) browser may prompt you for a user name and password. If this
happens, try using another browser such as Firefox or Chrome, or possibly a
different version of IE.
- Unzipping problems: Many older unzip programs (including
the one built into Windows XP) cannot handle the extended zip format which
is used to compress these very large files. They vastly overestimate the
filespace needed to unzip the files. We've also had one reported file corruption
problem using the Windows 7 unzip. We recommend using
7-zip on Windows and the
standard zip/unzip programs on other operating systems.

- This data replaces the corresponding tiles in the Spring 2011
Arrowhead collect EXCEPT in the "arrowhead" project folder, the "previous"
folders in the q250k folders, and in the county mosaics. Data is
available for download from the
"duluth_fall_2012" projects folder, the
folders, and the

- Spring 2011,
Carlton, Cook, Lake and St. Louis counties, part of Itasca County, and
Voyageurs National Park in Koochiching County.
Map showing block boundaries
- Data is available on the FTP site in different places, depending on
whether or not it has been replaced by the 2012 Duluth Area collect:
- Central Lakes: Collected Spring 2012. The data covers
Aitkin, Cass, Hubbard, Itasca, Todd and Wadena counties and a portion of
- Twin Cities Metro: Collected Spring and Fall 2011. The data
cover Anoka, Benton, Carver, Dakota, Goodhue, Hennepin, Isanti, Kanabec,
Meeker, Mille Lacs, Morrison,
Ramsey, Scott, Sherburne
and Washington counties.
- Data is available on the FTP site both by county (in the
county folder) and by block (in the
projects folder). See
showing block boundaries.
- Tile naming for the Dakota Block, Metro Block and Maple Grove Block: Since the
point density of these collects is higher than the other blocks (2
points/square meter for the Dakota Block, and 8 points/square meter for
the Metro and Maple Grove blocks), the vendor tiled the las files further, breaking each standard
tile into 16 additional tiles. They are simply appended an A, B, C, or D
starting in the upper left and proceeding in a clockwise direction. A
sample image, taken from the
tile index map that is on the site, shows a single tile with the
sub-block lettering scheme. A sample tile name would be:
4243-02-30_a_a.laz. Also, there is a tiling scheme feature class in the
elevation_data file geodatabase.
