Paper Abstract

The integration of several data types, including remotely-sensed imagery and cartographic data, has been accomplished by reprojection of the data to match a common map base in the Universal Transverse Mercator (UTM) projection. The resultant reprojected aircraft multispectral scanner (MSS) imagery, digital terrain models afIVO, and land use maps are available at the EROS Data Center, U.S. Geological Survey (USGS) in Sioux Falls, South Dakota as digital data sets that have areal coverage corresponding to the USGS 7 1/2-minute topographic quadrangle maps in the Los Angeles Basin. The three data types are: Thematic Mapper Simulator (N8001 scanner) MSS imagery; Digital Land Mass Simulator (or Arc-Second) DTM and the Environmental Sciences Research Institute land use files for Los Angeles. The techniques for data integration included: 1) control point selection, based on common features located in image and map; 2) map base calculations, based on the coordinate locations of the features on image and map; 3) image reprojection using a bilinear resampling algorithm, based on calculated map projection parameters; 4) mosaicking of reprojected images, based on offsets of the images within the mosaic map base; and 5) quadrangle area extraction, based on the boundaries of USGS 7 1/2-minute quad maps. The common map base concept was used because a common map projection allowed all the data to be spatially-registered when the unique projection differences between imaging sensors and cartographic files were minimized by reprojecting the data to approximate the UTM map projection.
