Visualization of condition irrigation building and canal using web GIS application

The implementation of GIS based application is growing rapidly in many areas such as business, government, or public services. Potential implementation of a GIS-based application then applied to the mapping of conditions and irrigation building and canal. The application will display the latest information on the condition of each building irrigation in Rentang area, covering three districts namely Majalengka, Cirebon and Indramayu. This area has about 1000 buildings irrigation and segment that connects between buildings. In order to present the interactive map and running in a web environment, the map should be processed using a series of stages of preparation of maps using GIS software such as ArcGIS, Quantum GIS, PosgreSQL and PostGIS, GeoServer, and OpenLayers. The resulting map is then divided into three main layers based on category object to be displayed, that is the main irrigation channel, secondary channel and tapping buildings. Users can see the position and condition of each object which is represented by a different color for each condition: green for good conditions, yellow for minor damage and red for major damage. This application is expected to help the units involved in obtaining a general overview of irrigation in certain areas quickly and accurately.
