The beginning of the book contains substantial introductory information about map projection families and distortions. Each projection is started with a useful summary of the context and usage of that particular USGS Store | USGS Store Original (pdf) 3 MB Map Projection on the Web (POW) Presentation POW will provide users with calibrated cartographic images that can be used for geologic mapping, analysis in a GIS, change detection, merging of dissimilar instrument images, and use in a host of other scientific applications (e.g., ArcMAP, QGIS, ENVI, Matlab, JMARS, etc.). Mimetype RLCM projection blocks (Cotillon and Mathis, 2017) With an area close to eight million square kilometers (km), the West Africa Land Use Land Cover (LULC) Project covers a large region, over a fourth of the Continent. Since the LULC data was derived using a sampling approach and completed at a 2 km resolution, it was important that the physical GeMS is intended to provide a stepping stone toward development of multimap databases, in particular the National Geologic Map Database (NGMDB).
