【国外标准】 Information technology - Homeland Security Mapping Standard - Point Symbology for Emergency Management

The primary purpose of this standard, Homeland Security Mapping Standard - Point Symbology for Emergency Management, is to establish a common set of symbols for use by mapmakers in support of emergency managers and first responders. It will allow users to rapidly interpret map data and to be able to disseminate consistent, usable information. This standard is applicable to all organizations that create maps or otherwise display features for the Emergency Management or First Responder communities. It is limited at this time to support portrayal of point features that relate to the emergency management and hazard mapping disciplines.
