Integration of Landsat Land Cover Data Into the Saginaw River Basin Geographic Information System for Hydrologic Modeling.

Abstract

A May 1977 Landsat-2 scene that covered approximately 85% of the Saginaw River Basin was classified into five land cover categories (urban, agriculture, forest, freshwater wetlands and open water) using a closest centroid classifier. The Landsat digital data were geometrically corrected to conform to a UTM (Universal Transverse Mercator) grid before classification. The 1.1-acre Landsat land cover classification data base was converted to 40-acre grid cells (six-by-six blocks of Landsat pixels) using an aggregation scheme and was integrated into the Detroit District's existing grid cell data base. A regression relationship between unit hydrograph parameters and the Landsat land cover classification was developed. The results indicated that the Landsat-2 land cover data were suitable for the Corps of Engineers hydrologic model. (Author)
