comment Why does Floyd-Warshall not return all pairs in my pgrouting SQL?
Ok, I am wrong. I checked the algorithm at Wikipedia. I apologize for not doing this before - was a long day... So, the algorithm returns only the pairs which are still unknown. Thus, all pairs and ways until node 15 are already calculated. The missing path is only 16 to 17. That explains the efficiency in storing all paths.

Actually, the ASCending order of maximum cost delivers a lot of nodes with zero or little costs. Investigating.

Changed DESC to ASC as it was an error in the SQL code.

@JohnBarça, referring to the minimax facility location in Wikipedia, I think the point search for the point which minimizes max(min(distance)) is wrong. Summation over the max(min(distance)) could be a solution. I'll try later.

comment QGIS Contour plugin: Creating complex isolines leads to isolated areas
I need to bring this up again. Is there a way to get finer interpolations with QGIS in the meantime? I have again run into this problem and find it very problematic. Maybe should I switch to ARCgis network analyzer?
