DESIGN AND IMPLEMENTATION OF A WEB-GIS PLATFORM FOR MONITORING OF VEGETATION STATUS.

The systematic analysis of crop condition monitoring using high spatial resolution satellite images is significant for decision-making and agricultural food production management. In the present paper, the web-GIS system has been designed and developed to accumulate spatial information, computing vegetation indices, and highlight Land Use Land Cover (LULC) changes. The developed system was tested using Landsat-8 satellite images. The system preprocesses the Landsat-8 images for obtaining better surface reflectance, spatial and temporal resolutions and computes vegetation indices for crop condition monitoring. The developed web-GIS system provides an online mapping tool, vegetation indices statistics, download function with various standard formats, opacity function, image overlay, project wizard, and Geo-Mapper Application. Additionally, the system also offers vegetation status maps and its statistical values, which utilizes in further applications. In conclusion, the web-GIS system affords a dynamic user interface, which is useful for decision support and near real-time data with its comprehensive abilities. [ABSTRACT FROM AUTHOR]
