BasqueRoads: A Benchmark for Road Network Selection
Résumé
Road network selection is one of the major issues of map generalisation, as new papers are proposed every year since
the first attempts of automation in the 1990’s (Thomson & Richardson, 1995). New methods are regularly proposed
because selecting roads for maps at smaller scales is a complex problem. Roads are at the same time present in maps to
enable car navigation tasks, and because they are structuring elements that reveal the nature of the landscape (urban,
rural, mountainous...). So road selection is not only about retaining the most important roads of the network, but the
preservation of topology and connectivity is essential, as well as the preservation, or the typification of road patterns
(e.g. a ring road), and the preservation of local density differences (between urban and rural areas for instance). It is rare
to see comparisons of road selection techniques in the literature, because of the lack of open source in map
generalisation, but also because of the lack of a common dataset to benchmark these techniques; new propositions on
road selection are most of the time tied to their own dataset and use case. This is why we think that this BasqueRoads
dataset could be useful to advance on this topic of road network selection.
