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 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).
