Linking Data with GISLinking Data with GIS

The Urban Inequity Survey (UIS) data is mapped through GIS to develop capacity among multiple city stakeholders to design the pro-poor urban policies.

Mapping city indicators is the most effective tool to convince the policy makers to use solid information to guide their daily management and long term strategic planning of their cities
