Geo-spatial data have been successfully used for description of spatial patterns, quantitative modeling, spatial predictions and management of natural resources at regional and global scale. A gap between the demand and supply of geospatial data for natural resource management is felt, in order to ensure sustainable development amidst large scale exploitation of natural resources. To fill this space, an online book project is undertaken by Gatha Cognition, inviting researchers, academicians, planners and managers to contribute original research/review papers on following themes.
