MAPP is a tool to map complex events – such as armed conflicts, protests, or humanitarian crises – as they unfold. Working as an aggregator of data in different media formats, as well as a powerful data visualisation platform, MAPP enables its users to make sense out of diffused and partial bits of information. Mainly developed as a front-end visualisation tool, MAPP provides access not only to the granular details of each singular event in a given dataset, but also, through interactive graphs and charts, it allows for temporal and spatial trends to be revealed. A participatory tool, currently at proof of concept stage, MAPP is being developed by the research cluster Forensic Architecture (Goldsmiths, University of London), in partnership with Amnesty International.
