  • Geobrowser: A geobrowser, or a virtual globe, is a three-dimensional, computer generated representation of the Earth or another world. Using computer modeling, satelite and aircraft imaging, it allows the user to view different aspects of the environment by rotating it and changing the angle, as if flying over an area by airplane. A geobrowser may include things like roads and buildings. It can also show weather patterns, like the movement of storms, as well as updated images of the changing geographic landscape including disasters. Examples include Google Earth and World Wind.
  • Geographic Information Systems (GIS):   Software Programs that allow users to capture, store, retrieve, analyze and display spatial data.
  • Geography Markup Language (GML): The XML grammar defined by the Open Geospatial Consortium to express geographical features.  GML serves as a modeling language for geographic systems as well as an open interchange format for geographic transactions on the internet.  The ability to integrate all forms of geographic information (raster and vector) is key to the utility of GML.
  • Geospatial: A term used to describe the combination of spatial software and analytical methods with terrestrial or geographic datasets. The term is often used in conjunction with geographic information systems and geomatics, never separately.
  • Keyhole Markup Language (KML):  KML is a file format used to display geographic data in an Earth browser such as Google Earth, Google Maps, and Google Maps for mobile. KML uses a tag-based structure with nested elements and attributes and is based on the XML standard.
