Minnesota Digital Elevation Model - Tiled 30 Meter Resolution

This page last updated: 2006-08-09 09:16:32.0
Metadata created using Minnesota Geographic Metadata Guidelines


Metadata Summary

Originator U.S. Geological Survey
Abstract This 30 Meter DEM is a copy of the USGS 1:24,000 scale Level 2 DEMs for the State. There are three quadrangles known be be Level 1 DEM data: Town Line Lake (q1925), Grand Portage (q1261) and Grand Portage OE N (q1161).
Use Tips A digital elevation model (DEM) product produced at a 30 meter sampling interval using a variety of production processes. Data have been converted from the original USGS DEM format to ARC GRID and then to EPPL7 format. This file contains one attribute ELEVATION that is elevation in feet. It is useful for large scale hydrologic and other land surface investigations

Attribute Accuracy
Logical Consistency Not Applicable
Completeness
Horizontal Positional Accuracy Source layer dem30im3: Unknown
Vertical Positional Accuracy Source layer dem30im3: Vertical accuracy specifications for dem DEM data depend on the production methodology, photogrammetric source, and degree of editing. A vertical RMSE of 7 meters or less is the desired accuracy standard. A RMSE of 15 meters is the maximum permitted. Distinct north-south tonal banding is visible in quads with larger RMSE's. This data noise becomes especially prevalent in derived products, such as hillshades, aspect, and slope layers.
