If ISRO just maps the outline of slum area, it will look like patches on the map and all that government would be able to get is how much sq. kms are covered. Then the estimate of number of people living in slum areas by multiplying it with population density will arrive at a figure that would most probably be far from the reality. And the number of houses built for slum dwellers will fall short in numbers and new slums will start taking shape. IMHO, this needs much more ground work for surveying these areas than simply drawing them on the map while sitting at home. But yes, the maps that we prepare can serve as a good base for survey agencies. We need to identify what all amenities or POIs need to be mapped in addition to boundaries, lanes, public water taps/handpumps etc. that will be helpful to the government in executing this project. regards, Nishant -- How about some patent on "(a+b)2 = a2+2ab+b2".
