Exploring Curved Schematization
Found in: 2014 IEEE Pacific Visualization Symposium (PacificVis)
By Arthur Van Goethem,Wouter Meulemans,Bettina Speckmann,Jo Wood
Issue Date:March 2014
pp. 1-8
Hand-drawn schematized maps traditionally make extensive use of curves. However, there are few automated approaches for curved schematization most previous work focuses on straight lines. We present a new algorithm for area-preserving curved schematization...
 
Delineating imprecise regions via shortest-path graphs
Found in: Proceedings of the 19th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems (GIS '11)
By Bettina Speckmann, Mark de Berg, Wouter Meulemans
Issue Date:November 2011
pp. 271-280
An imprecise region, also called a vernacular region, is a region without a precise or administrative boundary. We present a new method to delineate imprecise regions from a set of points that are likely to lie inside the region. We use shortest-path graph...
     
A new method for subdivision simplification with applications to urban-area generalization
Found in: Proceedings of the 19th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems (GIS '11)
By Bettina Speckmann, Kevin Buchin, Wouter Meulemans
Issue Date:November 2011
pp. 261-270
We introduce a local operation for polygons and subdivisions called an edge-move. Edge-moves do not change the edge orientations present in the input and are thus suitable for iterative simplification or even schematization. Based on edge-moves we present ...
