GEMA connected geospatial and emergency-management practitioners in a voluntary cross-sector network. Its public profile describes knowledge-sharing and capability across emergency-management work. Such connections supported people who needed to collaborate across organisations when geographic information had to be assembled and used quickly.
LINZ lists GEMA among New Zealand’s geospatial groups. The association describes emergency management through reduction, readiness, response and recovery, placing location information and shared methods across the disaster-management cycle.
