Change Classification


2000 CLASSIFICATION PROJECT

Project Overview

This is a contract project (SG-01-69) sponsored by the Metropolitan Council to carry out classifications of multi-temporal Landsat TM data covering the seven-county TCMA. The classifications use imagery acquired in 2000 and include three levels of specificity for land cover type, including percent impervious surface area for the urban/developed classes (table 1).

Table 1. Classification scheme of for land cover classification in the TCMA.

Level- 1	Level- 2	Level- 3	Description
Urban (Artificial Surfaces)	0-4% Density 5-10% Density 11-25%Density 26-50% Density 51-75% Density 75-100% Density	0-100% Imperviousness	Level-2 urban density is based on the impervious classification
Agriculture (Planted or Cultivated)	Cropland	Cropland	Corn, soybean, small grains, hay, pasture, etc.
Agriculture (Planted or Cultivated)	Planted trees & grasses	Planted trees, shrubs & grasses
Forest	Coniferous	Upland conifer	White Pine, Red Pine, Eastern red cedar
	Coniferous	Lowland conifer	Tamarack
	Deciduous	Upland deciduous	Oak, Maple-Basswood, Aspen, Box Elder, Oak woodland-brush land, Disturbed deciduous woodland
	Deciduous	Lowland deciduous	Floodplain Forest, Lowland Hardwood, Aspen forest temporarily flooded, Black Ash swamp, Mixed hardwood swamp, Aspen forest saturated
Non-forested vegetation	Upland shrubland� & herbaceous	Upland shrubland	Upland shrubland
	Upland shrubland� & herbaceous	Upland herbaceous	Grassland with sparse deciduous trees, Grassland with sparse conifer trees, Mesic prairie-tall grasses, Dry prairie-medium tall grasses Dry oak savanna, Mesic oak savanna
	Lowland shrubland & herbaceous	Lowland shrubland	Temporarily flooded shrubland, Alder swamp, Wet meadow shrub subtype, Willow swamp
	Lowland shrubland & herbaceous	Lowland herbaceous	Wet meadow, Poor fen, Rich fen, Cattail marsh, Mixed emergent marsh
Water
