Workshop details

Following the recent evolutions of cartography, the 23rd edition of the workshop will highlight propositions of map generalisation and multiple representation methods and applications for interactive multi-scale visualisations of spatial data. Topics of interest include those where thematic or reference cartographic or geographic data (2D or 3D) are generalized, simplified, or aggregated in any way.
