file extension SHX - ArcView Shapefile shape index format
File extension SHX description:
shape index format; a positional index of the feature geometry to allow seeking forwards and backwards quickly
The ESRI Shapefile is a popular geospatial vector data format for geographic information systems software. It is developed and regulated by ESRI as a (mostly) open specification for data interoperability among ESRI and other software products. A shapefile commonly refers to a collection of files with .shp, .shx, .dbf, and other extensions on a common prefix name (e.g., "lakes.*"). The actual shapefile relates specifically to files with the ".shp" extension, however this file alone is incomplete for distribution, as the other supporting files are required.
Shapefiles spatially describe geometries: points, polylines, and polygons. These, for example, could represent water wells, rivers, and lakes, respectively. Each item may also have attributes, that describe the items, such as the name or temperature.
