GIS 4035c Remote Sensing of the Environment Dr. Charles Roberts Land Use/Land Cover Mapping Perhaps the most common use for aerial photographs is land use/Land cover mapping. This is an important land classification system for remote sensing researchers, because it is designed to work with aerial photographs and satellite imagery. It has been adopted worldwide. We will examine the original Anderson system, and then we will examine the local version; the Florida Land Use Land Cover Classification System. Anderson Land Use/Land Cover Classification System The Anderson Land Use/Land Cover Classification System was developed in coordination with ERTS-1 (Landsat 1) and was designed to map land use at a national scale through standardization. The system is designed to use land cover as a surrogate for land use. What do we see on an image, pattern or process? Land cover is used as a surrogate for land use, but it has its limitations. For example, forest is land cover while logging, camping, and hunting are land use. You cannot tell which is the predominate use for a forest parcel. The Anderson system is used to standardize land use mapping in the United States and has been designed for various levels of sensing systems. There are actually three levels of classification systems that have been designed for different imagery: Level 1: The most general category, for the first Landsat MSS at 80m Resolution, creating maps of broad regions. Level 2: The most common category, for high altitude photography (NHAP and NAPP) 40- 80,000 ft. This is used to map similar land uses in the city. Level 3: Resembles zoning maps, medium altitude (under 10-20,000 ft.) photography. These show individual properties.
