The University of Minnesota has received several IKONOS images in support of two NASA Earth Science Enterprise Applications projects. Our overall objective is to evaluate the potential of high-resolution satellite imagery for mapping and analysis of land and water resources at local scales in Minnesota. The sites selected were chosen to represent a range of landscapes and applications including: (1) forest cover type mapping using a multi-seasonal sequence of five image dates, (2) mapping the extent and severity of forest damage in the Boundary Water Canoe Area Wilderness during a severe storm in July 1999, (3) urban land use mapping, with comparisons to Landsat classifications of land use change, in two rapidly developing suburban areas, (4) classification of lake water quality in a city with over 300 small lakes, and (5) agricultural crop management. We have found the IKONOS data to be of generally high quality with good potential to extend satellite remote sensing to applications beyond what has been traditionally done with aerial photography.
