Mineral Resources On-Line Spatial Data
Geospatial data format developed by ESRI, Inc. Typically this term refers to three coupled digital files, provided together, in which the geographic information is encoded in two, one whose extension is .shp, the other having extension .shx, and the attribute information is encoded in a third having extension .dbf.
