Overlay Analysis using ArcGIS Desktop

This video about the overlay analysis using shapefile, which is having different weightage and Ranking based on the specific criteria. For the demo purpose, I have used only two layers. Normally this method is used in many Geospatial Applications, viz., Ground Water Prospect Mapping, Solid Waste Management, Ground Water Potential Pollution Map, Drastic Index, Curve Number Analysis, Soil Erosion, etc using Remote Sensing and GIS. Please share your views. Any further updates/modifications are welcome.

Thank you..
But how we can calculate the weight of each criteria?

Very useful and was just what i needed to solve a problem. I am so grateful. But can you provide the source of the equation you used.

Great, can I just ask how about (my input is a land use raster) how can I apply weighted overlay using aritmetic operations ?

[bernardasiedu]

heollo please make tuto how to make method galdit or drastic please
