地理信息系统(GIS)是一个收集地理信息系统或工具,并使用这些信息来管理、操纵或分析目的为更好的决策与地理位置相关的问题。1968年,地理信息系统(GIS)是首次被罗杰·汤姆林森。在现代社会,这种技术使用数字空间数据库即使用数据从卫星图像,数字化地图和数据库设计事务(Rigaux,2001)。在过去的二十年里,GIS已与许多技术提供更好的结果合并,将用户新需求的更有效率。从1990年代初开始当使用所有这些数据存储在关系数据库在大型计算机上进化的小型机,GIS与不断变化的基础设施得以持续发展。分散的计算环境和基于Web的技术提供了新的机会基于GIS的应用更加强大和协作和更容易使用的终端用户。近年来,高效的数据处理技术被用来包含所需的巨大和复杂的数据存储和分析的目的,也为全球传输数据。

Geographic Information System (GIS) is a system or tool which collects geographical information and uses this information to manage, to manipulate or for analyzing purpose for better decision making with regards to geographical locations. In 1968, the term Geographic Information System (GIS) was promoted by Roger Tomlinson for the first time. In modern days, this technology uses digital spatial database i.e. using data obtained from satellite images, digitizing maps and database designed for transactions (Rigaux, 2001). In the last two decades, GIS has merged with many technologies providing better results and incorporating new demands placed by users more efficiently. Starting from the early 1990s when all this data used to be stored in relational databases on mainframe computers to evolution of minicomputers, GIS continues to evolve with the ever changing infrastructure. The fragmented computing environment along with Web based technologies provides new opportunities to GIS based application to be more powerful and collaborative and much easier to use by the end user. In recent years, efficient data handling techniques have been used to incorporate the enormous and complex data required for storing and analyzing purposes and also for transferring data worldwide.
