基於鎖孔標記語言(kml)之Web GIS的應用-以農業天然災害防治為例

Abstract

With the rapid development of information technology, the application of information communicaton technology, such as in industry, agriculture is getting popular. Geographic information system (Geographic Information System, GIS), is a powerful software that allows a variety of ways to present information in space. As Geographic Information System popularizes relevant industries start to analyze its data and make decisions from GIS. To what degree can we apply Geographic Information System in agriculture. For example, Japan actively takes advantage of GIS to establish the database of agricultural geography. Japan is working on field server to collect temperature, humidity, sun exposure, and soil moisture capacity in their crop cultivation areas through this monitoring system. It can help farmers fertilize and deliver drugs on their farms effectively, and lower the cost of production. People in developed countries can apply GIS to establish the limited years of the agricultural drainage pipelines, the database of repair records, and provide immediate disaster information. People combines the ground inspection equipment with satellite telemetry and it can work on the investigation of agricultural damage which now is done by men. Severe due to climate change in recent years, the showers, typhoons, tsunamis and other natural disasters continue to occur in the world, causing agricultural damage to property, countries pay more attention to disaster prevention and rescue work. This thesis aims first to discuss the structure of Keyhole Markup Language (KML) and the practicability in applying its relevant techniques. Take actual agricultural natural disasters for example. We can use KML to explore its related map database, and combine the current information equipment, such as web pages, smartphone, to accomplish the quick geographical location reports of agricultural natural disasters, analyze them on web pages, and upload image of disaster. Also use the portable KML document files, file archives classified according to their content, easy to build search and document files. The result of this thesis can help to explore the information techniques and Web GIS in agricultural disaster prevention, and understand and plan this information equipment. It also allows users to understand the scope of the disaster area to provide disaster prevention and exploration staff, methods of prevention and disaster reduction in real time for disaster countermeasures.
