Cartographic Symbology for Crisis Mapping: A Comparative Study

Abstract

Cartographic symbols on crisis maps serve as means of depicting information about the position, properties, and/or numerical values of objects, phenomena or actions specific to crisis mapping. Many crisis cartographic visualisations require simple, clear, categorised and visually organised symbols that can be easily read and understood by a wide range of crisis map users. Cartographic symbol sets for crisis mapping depend on effective graphic design, good availability (sharing and promotion, dissemination and promulgation) and standardisation (ensuring the general and repeatable use of map symbols). In this research, our aim was to examine the extent of these challenges in current cartographic symbology for crisis mapping. Through a comparative study of prominent symbol sets, we analysed efforts invested so far and proposed future directions. The results of this study may be of assistance in understanding less unified or coherent symbologies currently in use, or in revising or amplifying existing sets for future publication.
