A geographic information system (GIS), is any system that captures, stores, manages, analyzes, and presents data that are linked to any specific location. GIS is a system which is developed for specific purpose or application. So the system has its own boundaries. A concept beyond GIS that has no such restrictive boundaries is spatial data infrastructure (SDI). GIS finds its applications in resource management, asset management,software development service, Digital Analysis of Aerial data, Map Analysis, Data Capture and Conversion etc. An active GIS market has resulted in lower costs and continual improvements in the hardware and software components of GIS.
