Video Maps

Video maps contain georeferenced video streams that allow for new types of interactivity. For example, video layers can be combined with traditional vector layers, or the projection of a video layer can be adjusted by the user.

Flow Maps

We develop algorithms for creating flow maps showing linear movements between two places with curved lines of varying width. The geometry of flows is bent to reduce the number of graphic conflicts among flows with the goal to increase readability.

Color Oracle: Design for Colour-deficient Vision

Eight percent of men are affected by color vision impairment – they have difficulties distinguishing between colours. Barrier-free color design is important for this large group of readers.
Color Oracle is a free software application that simulates colour-deficient vision to help designers ensure their graphics are barrier-free.

Altases for E-books

Digital cartographic atlases have replaced traditional paper atlases, but cartographers have not yet fully embraced the potential of multi-touch tablet computers, such as the iPad. We explore the characteristics of e-book atlases, which are positioned between traditional printed atlases and digital atlas information systems.

Game Devices for Geovisualisation

Globes, block diagram and maps can be connected with game devices, such as gamepads, opening new ways of interaction with geospatial visualisations.

Dot Maps

We explore methods from computer graphics for improving the placement of dots in dot maps. Simple random placement leads to local clustering of dots that is misleading, as these patterns suggest a spatial pattern that may not exist. Random placement also creates overlapping dots, which are not countable. We adapt sampling methods from computer graphics to solve these problems.
