I'm trying to solve the transport problem and make the visualization
using Geotools.
In attached pic that is what I mean. My car is between V3 and V4. Its
position can I get with a query like "*SELECT ST_Line_Interpolate_Point*(
linestring1, 0.6);" Ok, I got it's position, but how can I receive nearest
real vertices v3 and v4? I hope, there is a method with only one query.
Thanks.
