ICC 2013 : Mixing, blending, merging or scrambling topographic maps and orthoimagery in geovisualization ?

Topographic maps, orthoimagery, vector thematic data convey various views of the real world. Geovisualization tools and geoportals widely provide these heterogeneous data to users. They bring users to co-visualize them in order to make suitable visualizations adapted to a task, a purpose or an application. Nevertheless, existing tools do not help to make satisfactory, elaborated and efficient visualizations. This paper presents a part of a PhD work in progress: conceptual and technical issues about proposing raster and vector co-visualization methods are detailed. The authors aim at proposing tools to explore a continuum of possible visualizations, between the photorealism of an orthoimage and the abstraction of a topographic map. Three methods to reach this objective are presented and discussed: patchwork between a map and an ortho-image, adaptive symbolization when overlaying data and fluid camouflage of a map in an ortho-image.
