With the recent growth of mobile GIS technology, many companies now offer various services and equipment to perform different mobile GIS tasks. Though ESRI is a common choice, with its reputable name and excellent ArcPad software, there are now many other products and organizations to choose from. These include MapXtend software by MapInfo, GeoExplorer handhelds and mobile tracking devices by Trimble, ERMapper, and various GPS tracking solutions.

the desktop computer (ArcIMS Tracking Server). MapInfo is a major alternative

products to serve GIS to the web. MapInfo MapX and MapBasic are tools for
developers to create custom GIS applications. Intergraph offers a mobile GIS
platform called IntelliWhere, which brings Intergraph GeoMedias GIS
