I'm using PostGIS and Leaflet for positioning elements on map. Because of GNSS (GPS) error, points are not always on road. Is there any way to eliminate that error and position element to road? I don't have roads in database (for now).

Elements are points with gps coordinates and some attributes. Is there any way to map match elements?

Mr.Code

If you load the vector roads you can use PostGIS ST_Snap https://gis.stackexchange.com/questions/269112/snap-point-to-point-with-st-snap-postgis – Mapperz Oct 28 '18 at 01:09
ST_Snap snaps to the nearest vertex of the geometry, not the nearest point, and roads have to be in postgis too. – Zoltan Oct 28 '18 at 06:55
Nearest Neighbor search with ST_ClosestPoint, this is a close duplicate question. – geozelot Oct 28 '18 at 09:15
