GIS & Remote Sensing

Geographical Information Systems (GIS) is a technique used to analyze data that is connected to a specific location. Shelter Associates uses GIS to integrate mapping and socio-economic data that can be analyzed spatially and become critical in planning for the poor. This data includes overall census information, as well as information about infrastructure and access to facilities such as toilets, water, etc. The socio-economic data that is collected includes employment, caste, education and family size. This information can be graphically overlaid onto the remote sensing image to get a slum-wide or city-wide view of the data. Below are three examples (for Pune, Sangli and Solapur) of how Google Earth can be used to present GIS data. Several slums are outlined: the blue bubbles contain information about the slums and the yellow bubbles contain information as well as a link to a detailed factsheet (pdf) for that slum.

Why Shelter Uses GIS

Shelter Associates pioneered the use of GIS in the late 1990s for poverty mapping. The broad objective was to create critical spatial data about the degraded areas that would aid inclusive city planning. Moreover, this helped validate the existence of the poor in the city.

Examples of GIS Use with Slums

Below are some examples of how we use GIS. Some of these use the Google Earth Plugin, you can download it by clicking here.

Pune

Pune has around 560 slums split up into 14 wards. This is an example of the remote sensing of the three slums in Bhawanipeth. Some GIS data is available in the yellow bubbles.

Sangli

Sangli had 78 slums. This is an example of the remote sensing of five of these slums. Indira Nagar Zopadpatti is the largest slum in Sangli. Some GIS data is available in the yellow bubbles.

Solapur

Solapur has 220 slums. This is an example of the remote sensing of four of these slums: Bagle Vasti, New Jagjivanram, Rahul Gandhi Nagar and Bhagwannagar. Some GIS data is available in the yellow bubbles.
