The potential of web-based participatory mapping technologies for use in urban planning and the development of spatial information in Delhi's slums is explored in this article (barrios). While mapping technologies are becoming more popular in affluent nations, they are being used less often in the informal settlements of developing nations owing to problems associated with widespread informality, illegality, and a dearth of data, personnel, and capital. The purpose of this research was to develop a course for Sector-level planning officials in Delhi's slums that would use Google My Maps for participatory mapping. Our primary focus was on cataloguing and mapping existing and proposed public assets and infrastructure. This study's overarching goal is to demonstrate how such instruments may aid in the planning of informal settlements and the generation of locally created spatial information.
