| General Info
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.

MnTOPO: A web application for viewing, printing and
downloading high-resolution elevation data for Minnesota collected using lidar
technology
- 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
easily fixed.

Data Download
- 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 ( gisinfo.mngeo@state.mn.us ) if you are having trouble finding anything.
- Contents and
filesizes of lidar geodatabases:
- 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 do not 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. FileZilla works well.
- 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: Some older unzip programs 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 recommend using 7-zip on Windows and the standard zip/unzip programs on other operating systems.
- Flight lines and dates of acquisition (where available):
- Problem with some LAS files in Stearns, Sherburne and Hennepin
counties, near Wright Co. border
- The following files are missing some data (see graphic with missing areas outlined in red): 3542-22-07, 3526-22-59, 3542-25-16, 3526-19-62, 3542-26-14, 5158-08-11, 3542-20-03, 3526-22-60, 3526-22-57, 3526-19-64, 3542-21-05, 3542-20-02, 3542-26-13, 3542-24-16, 3542-19-01, 3542-28-12, 3542-28-11, 3526-19-63, 3542-30-09, 3526-22-56, 3526-22-58, 3526-21-61. If they can be fixed, replacements will be published.

ArcGIS 10.1 Toolbox (MnDNR)
Streamlines downloading and merging lidar data associated with a polygon of
interest from within ArcGIS software
Requires ArcGIS 10.1 Service Pack
1 or above.
Hillshade layer (lidar-derived, black-and-white image) on MnGeo's WMS image service. Documentation
Areas Covered:
- Arrowhead:
- Fall 2012, Duluth Area, taken after the spring 2012 flood.
- Maps showing area covered
- Documentation
- 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
q250k
folders, and the
county folders
(the tiles but not the county mosaics).
- Spring 2011,
Carlton, Cook, Lake and St. Louis counties, part of Itasca County, and
Voyageurs National Park in Koochiching County.
- Map showing block boundaries
- Documentation
- 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:
- If it has NOT been replaced by the 2012 Duluth Area collect, 2011 data is available in the "arrowhead" projects folder, the q250k folders and the county folders.
- If it HAS been replaced by the Duluth Area collect, 2011 data is still
available in the
"arrowhead" projects folder, in the "previous" folder in the
q250k
folders and in the county mosaic (but not the tiles) in the
county folder.
- Fall 2012, Duluth Area, taken after the spring 2012 flood.
- Central Lakes: Collected Spring 2012. The data covers
Aitkin, Cass, Hubbard, Itasca, Todd and Wadena counties and a portion of
Koochiching County.
- Documentation
- Block boundaries map
- Data is available for
download from the
projects folder, the
county folder and the
q250k
folder.
- 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.
- Documentation
- Data is available on the FTP site both by county (in the county folder) and by block (in the projects folder). See map 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.
