Remote sensing and GIS combined to used for mapping, monitoring, planning and management for better and sustainable development of city, state and country.
There are many process in GIS and remote sensing, which can be used for creation of raster and vector database.
These data can be integrated with mathematical and statistical models/methods for planning and management.
Remote sensing images can be acquired temporally and in different bands for preparation of information in qualitative and quantitative with more accuracy. Different image processing methods can be adopted for creation of raster database.
GIS can apply to various fields for database creation, analysis, monitoring and planning using vector based analysis. GIS has many functions which can be used to create spatial and non spatial database.
In this article, application of remote sensing and GIS explained to understand the impact of urban on watershed.
In a natural watershed environment, structural changes of the watershed and their ecosystems are relatively slow (except under the condition of natural disasters such as fire, drought, and flood).

Very good article. Good to understand overview of SWAT. You may add some links in the article, like SWAT website. Also maybe in another article describe how QGIS could be used to QSWAT based modelling. Excellent work
Thank you for valuable suggestions.
