Note that I use a mixed multigraph model in https://github.com/kkdd/GraphFromOSM and its homeomorphic simplification also significantly reduces the number of nodes even for undirected edges.

No, every node which connects two OSM ways is deleted and they are concatenated by [homeomorphic smoothing](https://en.wikipedia.org/wiki/Homeomorphism_(graph_theory)#mixed_graph) [there](https://github.com/kkdd/GraphFromOSM), but under the following normal conditions: ```javascript function shallBeConcatenated(vertex) { if (!vertex.inGraph)...

Thank you for your explanation. I'm further going to think about this issue. Can horizon get the result of the sequence of road-network links (=edges) instead of the one of...

Thank you for your deep consideration. The 5th point seems important for selecting the optimal one of parallel edges in your example plot, shown as a yellow dashed line in...

Hi, Thank you for your comment. I'm sorry that I don't have a clear idea about the comparison of the search performance between the following: * B-tree based on S2geometry...

Hi, An above-mentioned idea is for avoiding trigonometric calculation for distance in the differential, or short-range, sense. I have no idea about the definition of Braun projection in proj. But...

ogr2ogr seems to work well with empty properties, {}. The following is a simple conversion test: ``` $ ogr2ogr -f GeoJSON -dim 2 poly2.json poly3.json $ cat poly3.json { "type":...
