The Polar Geospatial Center (PGC) was founded in 2007 and was originally called the Antarctic Geospatial Information Center (AGIC). In its early days, the AGIC's goal was to provide basic mapping and GIS services for the United States Antarctic Program (USAP), and was only a two-man project. As time went on, the program's credibility and size ...
SaTScan employs scan statistics to identify clusters of space and time phenomena. [1] Scan statistics use regular shapes (usually circles) of varying sizes to evaluate a study area. [ 8 ] [ 9 ] Within each circle, the software computes if the phenomena within the circle is significantly different than expected compared to the area outside the ...
Another important improvement was the introduction of radio and electronic satellites like Geos A and B (1965–70), of the Transit system (Doppler effect) 1967-1990 — which was the predecessor of GPS - and of laser techniques like LAGEOS (USA, Italy) or Starlette (France).
ERDAS IMAGINE incorporates geospatial image processing and analysis, remote sensing, and GIS capabilities into a single powerful, convenient package. ERDAS IMAGINE enables users to easily create value-added products such as 2D and 3D images, 3D fly-through movies, and cartographic-quality map compositions from geospatial data. C, C++: Proprietary
Geographic information system (GIS) is a commonly used tool for environmental management, modelling and planning. As simply defined by Michael Goodchild, GIS is as "a computer system for handling geographic information in a digital form". [66] In recent years it has played an integral role in participatory, collaborative and open data philosophies.
The Map Overlay and Statistical System (MOSS), is a GIS software technology. Development of MOSS began in late 1977 and was first deployed for use in 1979. MOSS represents a very early public domain, open source GIS development - predating the better known GRASS by 5 years.

MapServer was originally developed by Steve Lime, then working at the University of Minnesota — so, it was previously referred to as "UMN MapServer", to distinguish it from commercial "map servers"; today it is commonly referred to as just "MapServer", and is maintained by the MapServer Project Steering Committee (PSC).
