Crowdsourcing techniques have been widely employed to detect and map land surface dynamics, such as land use and land cover, human settlements, buildings, and crisis situations. These techniques are applied at regional and global scales to complement or substitute other specialized and expensive physical sensors aboard satellites, unmanned aerial vehicles, ground vehicles, and robots. This workshop will provide a forum for discussion of recent advances in crowdsourcing techniques for mapping global environments. Our goal is to bring together experts in global mapping who utilize Volunteered Geographic Information (VGI), User-Generated-Content, and Citizen Science to establish a common and sustainable ecosystem that will consolidate multi-disciplinary efforts from researchers and practitioners. CrowdMapping will be a key component of the ISPRS Geospatial Week 2023 hosted by the Arab Academy for Science, Technology and Maritime Transport, alongside other related workshops. Since this will be the first joint workshop of the organising team, we propose to allocate a single whole day of the ISPRS Geospatial Week for oral presentations, poster sessions, and hands-on demos aligned to the CrowdMapping context.
