There are more than 300 informal settlements in the metropolitan area of Guatemala. The goal of the Digital Mapping project was to design a crowdsourcing solution to identify risk factors and vulnerable urban areas, and test this solution in a number of pilot settlements. The mapping tool was developed and applied to 4 settlements. Information was collected by the 217 local residents and 59 field workers with the help of drones and mobile devices. It is expected that this data will help streamline and prioritize public policies and/or actions for disaster prevention in these vulnerable urban territories; there are currently negotiations underway to publish results in national databases. The information collected in the four pilot settlements is also available on an online platform. The project seeks to become a benchmark for multi-sector participation in the production of urban information and diagnosis.
