Emergency surveying and mapping support services are essential foundational work throughout the entire process of prevention, response, disposal, and recovery of emergencies. They constitute a critical component of the national emergency response system and represent a significant operational area for public-interest surveying and mapping geographic information work in the new era. To thoroughly implement the "National Natural Disaster Relief Emergency Response Plan" (State Office Letter [2016] No. 25) issued by the General Office of the State Council, the "Approval of the Feasibility Study Report for the National Emergency Surveying and Mapping Support Capability Construction Project" (Development and Reform Investment [2015] No. 3111) issued by the National Development and Reform Commission, and the "13th Five-Year Plan for Surveying and Mapping Geographic Information" (Development and Reform Region [2016] No. 1907), it is imperative to further strengthen the capacity building of emergency surveying and mapping support services to better serve emergency management efforts.
