Collaborative Crowdsourced Cloud Mapping (C³M)

Our Mission

The members of this WG will work on the intelligent capture and integration of geospatial information and knowledge in an online collaborative environment. This involves techniques for mapping the world with newly generated content that can be contributed voluntarily or as byproducts of people’s actions and moving (GNSS tracks, social media, telecommunication, etc). It also involves collaborative architectures, data models, platforms, services and apps for data sharing, linking, visualizing, geoprocessing and decision-making. Moreover the reasons, motivations and modes of user collaboration as well as topics related to openness, ownership, privacy and trust will be investigated within the WG or by means of relationships with other Associations and Organizations.

Collectively, an enormous amount of data is captured every day and at least 80% of them are or can be georeferenced. The aim of the WG is to study how all these data can be acquired, linked, assessed and improved in their quality and used for building a Free and Open Digital Earth. The increase of humanitarian crisis in the world has resulted in more collaboration to use new technology and digital skills to coordinate response. As well, the Sustainable Development Goals (SDGs) highlight opportunities to incorporate satellite and geospatial programs into long term projects.
