Working in C++/GEOS, I would like to find all line/line segment intersections in a set of polylines, to a user specified precision (i.e. lines that approach to within said precision are considered as intersecting).
I am led to believe this is possible (http://gis.stackexchange.com/questions/33619/permissive-open-source-planarize-algorithm/33635#comment46301_33635) but haven't found the right bits of the API.
I can intersect two lines segments but for a set of polylines, presumably there is a more efficient way than brute force pairwise comparison?
How do you set cluster tolerance?
