The Center for International Earth Science Information Network (CIESIN) at Columbia University has developed The Global Poverty Mapping Project whose goal is to
enhance current understanding of the global distribution of poverty and the geographic and biophysical conditions of where the poor live. Additionally, the project aims to assist policy makers, development agencies, and the poor themselves in designing interventions to reduce poverty.
We have highlighted the value of visualization such global problems before here and here and so this project is another great resource for both researchers and practitioners in the development space. Currently, it does not seem that the India maps have been published yet, however, they should be up soon.
