DATEA (2011-2014) was a digital platform for participative mapping (crowdsourcing). Initially, the platform focused on urban development in Lima, Peru. The platform has been used since 2010 to generate information by users of Lima’s Bus Rapid Transit (BRT) System or Metropolitano. It was also used to generate information about the state of bicycle lanes in the city in 2011. Both experiences oriented citizen reports and knowledge generated towards bettering these services. They also allowed for the expansion of the technological design of the platform towards a system developed in open code and released to the general public with a GPL license during the second semester of 2012. In 2013 the project received the support of the Avina Foundation.

Currently, the project is offline but serves as an example of a civic technology that allowed for bottom-up knowledge generation and analysis.
