Visualizing and Interacting with Geospatial Networks: A Survey and Design Space
It provides a systematic overview for researchers and practitioners in visualization and geospatial analysis, but is incremental as it synthesizes existing work without new techniques.
This paper surveys visualization and interaction techniques for geospatial networks, analyzing 95 papers to categorize methods based on representation of geographical and network information, visual integration, and interaction, aiming to balance information display with readability.
This paper surveys visualization and interaction techniques for geospatial networks from a total of 95 papers. Geospatial networks are graphs where nodes and links can be associated with geographic locations. Examples can include social networks, trade and migration, as well as traffic and transport networks. Visualizing geospatial networks poses numerous challenges around the integration of both network and geographical information as well as additional information such as node and link attributes, time, and uncertainty. Our overview analyzes existing techniques along four dimensions: i) the representation of geographical information, ii) the representation of network information, iii) the visual integration of both, and iv) the use of interaction. These four dimensions allow us to discuss techniques with respect to the trade-offs they make between showing information across all these dimensions and how they solve the problem of showing as much information as necessary while maintaining readability of the visualization. https://geonetworks.github.io.
