I am working on a school research project and was suggested to use OSM as a resource to find slums within Bangkok. I am very new to OSM and are unsure of how I can find areas within Bangkok that are considered slums. I mainly need the location/coordinates of the slums but polygons would be even better. If someone could point me in the right direction on where to start or what to read to help it would be much appreciated.
