GEOGRAPHIC INFORMATION SYSTEM (GIS) is an information system that can be used to manage, analyze and present geographically-referenced data. GIS is used in many applications such as natural resources management, urban planning, real estate and land records management, emergency planning, and environmental modeling. Geomatics, by definition, is a major stakeholder in GIS data acquisition and error modeling. Three dimensional point coordinates resulting, for example, from LIDAR data can be used in a GIS to delineate stream and river basins and study surface water flow. Data extracted from Remote Sensing sources was traditionally used in GIS to model large phenomena such as forest fires, global warming and drought conditions. GIS also has a major role in modeling transportation networks, handling emergencies, and managing surveying and mapping resources. Recently, GIS applications have shifted towards web-based services. A web client application can display, query, and analyze GIS data through the internet. Web-based applications such as Google Earth have become very popular and have introduced GIS concepts to the public. Many wireless GIS applications are also being developed for the navigation and vehicle-tracking market. |
