Call for Case Studies: Demonstrating the Impact of Open Community Mapping in Urban Climate Action
HOT and its allies in the mapping and climate science community are working to establish open community mapping as a key strategy in addressing urban climate challenges. The initiative aims to publish research in leading scientific journals and influence the IPCC’s upcoming report. To bolster this initiative, HOT invites case studies showcasing the application of open community mapping in urban climate and development action. These submissions will be instrumental in advancing the global recognition of open mapping.
