DEVELOPMENT OF A WEB GIS BASED DECISION SUPPORT SYSTEM FOR AGRICULTURE CROP MONITORING SYSTEM - A CASE STUDY OF SUGARCANE AGRICULTURE

摘要

The success of planning for developmental activities depends on the quality and quantity of information available on both natural and socio-economic resources. It is, therefore, essential to devise the ways and means of organizing computerized information system. These systems must be capable of handling vast amount of data collected by modern techniques and produce upto date information. Remote Sensing technology has already demonstrated its capabilities to provide information on natural resources such as crop, land use, soils, forest etc on regular basis. The role of remote sensing and GIS in agricultural applications can be broadly categorized into two groups inventory/mapping and management. While remote sensing data alone is mostly used for inventory, crop acreage estimation, crop condition assessment, crop yield forecasting, soil mapping, etc purposes, the management related activities like irrigation management, cropping system analysis, precision farming, etc. needs various other types of spatial, physical and Environmental information. The later needs to be integrated with remote sensing data wherein the functionality of GIS will be used. In the present study, techniques of remote sensing and geographic information system (GIS) have been used to monitor and map the Sugarcane crop at farm level. The Quick bird data of 60 cm resolution was acquired. It is geometrically corrected and Georeferenced for subsequent processing and analysis using Digital Image Processing (DIP) and GIS. Using various Customized tools available in GIS, a web based system is developed for monitoring the sugarcane after the preparation of Thematic layers at the farm level. This monitoring system helps the decision makers to take appropriate decisions in order to increase the crop production and other activities related to the crop. The Web GIS helps the non technical users to access the information and take appropriate measures to improve the crop production. With the development of these user-friendly monitoring systems the technology can be made available to common man apart from the Scientific Community.
