Pengembangan sistem informasi prediksi laju erosi Berbasis web

Abstract

Erosion is one of the parameters for the assessment of degraded land and the information of erosion in an area can be used as guidelines for land rehabilitation. The erosion can be predicted within Web-GIS which is integrated in the internet. The objectives of this study are to develop a Web-GIS based information system for predicting the rate of erosion, and to validate the system to calculate the rate of erosion in selected region. The system is built using open source software Mapserver and PostreSQL /PostGIS as Database Management System Software (DBMS) to store the spatial database. The programming language used in the development of the system includes PHP (PHP Hypertext Preprocessor), HTML (HyperText Markup Language) and Javascript. Framework ExtJS, OpenLayers, GeoExt and Mapfish is used to help creating the common functions and web interface.
