I added Filter/Spatial, and it worked. I also found out that Format/GeoJSON was necessary.

comment How can I use R-Tree to find points within a distance in Spatialite?
Can you, please, write an example, how to find all pairs of points close one to another? I can use it too. I'd prefer PostGIS over SpatiaLite after learning the latter more. After installing Python library for spatialite, compiling GEOS, P-something, and seeing things working differently in Python than in spatialite shell, I want SpatiaLite go to hell.

So, {1, 8, 9} are replaced because they are duplicates in {A, 8, 9; 1, G, 9; 1, 8, F}, or just because they are the rest of the subgraph? (after removing the internal nodes)

comment How to simplify a routable network?
Did you find any solution to this problem? I'm doing a similar task just manually, with a custom script: gis.stackexchange.com/questions/21823/…
