Reaching a Compromise between Contextual Constraints and Cartographic Rules: Application to Sustainable Maps.

Cartography and Geographic Information Society Journal, Volume 38, Number 2, page 79--88 - April 2011

Emerging mobile mapping applications create new constraints for cartographers. This constraints should be considered in addition to the traditional cartographic rules used to design maps. Legend colors could be optimized regarding those constraints. A challenge of such optimization concerns the preservation of map semiotic quality. In our research, we propose a quantification of the cartographic quality of a map regarding a given reference map, that consider semantic rules of association, differentiation and order supposed to be conveyed by map colors. Some mobile devices require less energy to display dark colors than lighter ones. Thus, in this paper, we consider the energy consumption as the contextual constraint to optimize. Map samples are designed, while taking into account some conventional uses of colors for relevant themes: hydrography, vegetation and the background layer. We discuss on how to find the best compromise between a contextual constraint (the energy required to display a map on a screen of a mobile device in our example) and the cartographic consistency on colors regarding the initial semantic relationships in the legend. This supposes to evaluate how far a map supposed to follow cartographic rules can be altered while preserving its semiotic quality.
