There are a number of file formats used for GIS systems that are relevant to Windows programmers as well as developers on other platforms. Some popular ones are:
1. Shapefile - this is a popular geospatial vector data format developed by ESRI as an open specification. It uses points, lines and polygons to describe e.g. wells, rivers and lakes. You can associate properties to each object like temperature or name. It is a file format used by ESRI's former flagship product, ArcView (now known as Arc GIS).
2. GML (Geography Markup Language) - an XML grammar developed by the OGC or Open Geospatial Consortium. (File extension: GML or XML). More information on the OGC website.
