Section 1 Overview
Originator U.S. Geological Survey
Title Minnesota Digital Elevation Model - 30 Meter Resolution
Abstract This 30 Meter Digital Elevation Model (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).
Purpose Landscape analysis, hillshade generation for cartographic products, and slope determination

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.
