Placing Sidewalk Vendors on the Map in Ho Chi Minh City

by Noalee Harel, Ruth Sappelt and Jackie Sly

Some urban treasures are hidden in plain sight. The documentary film "On the Map" shows how MIT professor Annette Kim and her research group, the Sidewalk Lab (SLAB), trained themselves to see anew in Ho Chi Minh City. In the process, they helped open the eyes of planners to one of the city's greatest assets: street and sidewalk vendors. Through rigorous observation and cartography, SLAB worked to protect the rights of these entrepreneurs and highlight their positive impacts on the city.
