Software, Application, or a System that is used to analyze, manipulate, and visualize geospatial data and databases is a GIS Software. These are robust packages that are used to handle a large number of data sets. The data sets and files are limited to spreadsheets and multimedia files like video drive files and imagery from various sources. Companies that are into GIS software are ESRI, HERE Maps, Google, Bing Maps and Autodesk, etc. Along with the big guns, there are also small open-source, free wares that are doing well in the industry. I will try to cover the most widely and known software in the latter part
