Emergency cartographic system based on national fundamental geographic data

Abstract

An emergency cartographic system named CartoEM using fundamental geographic data was proposed with the specifications for cartographic symbols to topographic maps and the existing GIS system and cartography system. The architecture and the data organization of the system were described. Then, some key issues of cartography with the system were investigated, such as cartographic representations, labeling, map-marking, dynamic arrows, and so on. The cartographic system realized the automatic configuration of symbolizing, annotation labeling, and the emergency thematic elements at last.
