Using the GDACS Satellite Mapping and Coordination System (SMCS)

Click a tab to get detailed help on this feature of the SMCS
The GDACS Satellite Mapping and Coordination system provides a communication and coordination platform where organisations may monitor and inform stakeholders of their completed, current and future mapping activities for ongoing emergencies. It makes use of both automatic data feeds offered by mapping organisations as well as allowing registered users to create their own areas of interest within a given event area and keep people updated on the mapping products they have or are currently producing. The end goal is to reduce duplication of mapping efforts and to also maximise awareness of existing products.
