Watershed Delineation

Image
Watershed Delineation - Any Study Area Water is important life-source of living things and plays an essential role in economic development and augmenting growth of agricultural sector and industrial activities especially in the angle of rapidly increasing population and urbanization. Thus analysis must be carried out on a watershed basis because all these processes are taking place within individual micro-watersheds. Watershed is not simply the hydrological unit but also socio-political-ecological entity which plays crucial role in determining food, social, and economical security and provides life support services to rural people. The above video provides step by step assistance to delineate watershed for any region of interest. Geographic Information System (GIS) is a computer-based tool that analyses and manages spatial data & Digital Elevation Model (DEM) can be used successfully to extract several watershed parameters. Delineat...

Mosaic Multiple Satellite Imagery

Mosaic Satellite Images Mosaic Satellite Images is certainly important and needed for most researchers and students, that too analyzing  larger study area covering two or more satellite scenes. Hence for providing better assistance, I am providing some productive ways for Mosaicing Satellite Images using Erdas Imagine. If  you have further doubts please visit this link below:  Tutorial - Mosaic Satellite Imagery Erdas Imagine is popular remote sensing software through which mosaic process can be effectively done. Open Erdas Imagine through which add the satellite imagery’s and proceed to raster option from which mosaic tool is visualized. Select Mosaic Pro add the satellite images to tool and run the process mosaic will be completed in few minutes. Things to Remember   When downloading satellite image make sure that each and every satellite image date does not exceeding two weeks, otherwise color variation will happen. This due climatic variation...
