Gradual Development of Different Image Analyzing Tools for Natural Resources Management

Sanjeev Sharma*, Churamani Khanal and Puskar Khanal

Remote sensing and Geographical Information System (GIS) offers an abundant opportunity to monitor and manage natural resources at multi-temporal, multi-spectral and multi-spatial resolution. It is an urgent need to understand the specialized capabilities of an ever-expanding array of image sources and analysis techniques for natural resource managers. In this article, we compile the various image analysis tools that can be used for natural resource management (agriculture, water, forest, soil, natural hazards). Comparative study of different tools was done, and importance of each tool was highlighted. The bibliographic study of the tools shows that the Google Earth Engine is being used nowadays for the image analysis because of its wide area of coverage. Finding shows that Global Mapper is used mainly for the 3D analysis, ENVI (The Environment for Visualizing Images) for beginners, hyper spectral image and Google Earth Engine (GGE) for the wide area analysis, multi spectral image and free of cost. This information is useful for the natural resource managers to understand and more effectively collaborate with remote sensing scientists to develop and apply remote sensing science to achieve monitoring objectives.
