Raster Elevation Data and Shaded Relief Maps for Minnesota
If you are looking for:
- Consistent resolution products for the whole state, go to the State section.
- Data beyond Minnesota, go to either the National or Global
Twin Cities Metro Area
The Elevation section lists several county and
city elevation data such as
30m DEM, City of St. Paul DEM, Hydrologically Corrected 10
Meter DEM, Ramsey County LiDAR, and Steep Slope Class Grid.

The National Elevation Dataset (NED) and the Shuttle Radar Topography
Mission (SRTM) datasets are two major elevation data sets available for
the U.S. They are distributed via the USGS Seamless Server.
What is the difference between NED and SRTM?
- National Elevation Dataset
NED is the primary elevation data product
of the USGS and serves as the elevation layer of The National Map. It has
three primary raster resolutions: 1 arc-second, 1/3 arc-second and
1/9 arc-second (approximately 30-meter, 10-meter and 3-meter
respectively). The 1/9 arc-second is created from data collected
Status viewer: Check the "Resolution", "Production Method" and
"Date of Update" layers. See the color legend by
clicking on the layer name.
Shuttle Radar Topography Mission (NASA,
SRTM obtained elevation data on a near-global scale using a specially modified radar system onboard the
Space Shuttle Endeavour in February 2000. The U.S. is covered by both 30-meter and 90-meter

Near-global coverage is available at 90-meter resolution.
GTOPO30 (Global 30 Arc-Second Elevation)
resolution raster data derived from a variety of sources.

ASTER DEM (NASA and Japan) v. 2 released 10/2011
Each elevation measurement point in this digital elevation model is
30 meters apart. Stereo-pair images are produced by merging two
slightly offset two-dimensional images to create the
three-dimensional effect of depth.
