WebSo far, we have talked about the overall idea of generalization – using data that is the correct level of detail for your map’s scale. A general-purpose map of a small town, for example, would likely show lakes, ponds, and reservoirs, while a small-scale map of a large region would show only the largest waterbodies (e.g., rivers, large lakes, and oceans). WebOur recent work has focused on geocoding, which turns textual place references into geographic coordinates, and geomorphometry, which analyzes and interprets landform objects and land surface parameters extracted from digital elevation models. RECENT PUBLICATIONS Chen Y, Zhou Q, Wilson J P, and Lang Y. 2012.
