[postgis-users] Best projection srid for topology

Hello all, I'm working on a many million lines topology project with OSM data in 4326 srid. I'd like to know if i should transform their geom in a meter srid ( like 3857). Should it be faster for the 'toTopoGeom()' function to work with geometry in 4326 or in 3857 srid? Thanks Marc

Hey, maybe you should choose whatever srid reduce the number of digits, for the sake of precision Cheers, Rémi-C 2015-05-27 17:32 GMT+02:00 Marc-André Goderre : > Hello all, > I'm working on a many million lines topology project with OSM data in 4326 > srid. I'd like to know if i should transform
