[postgis-users] Dividing an area to closest line

[nicklas.aven at jordogskog.no]

Hallo
 
My first time writing here.
 
The case is that I need to find the closest road from every point in the terrain. The roads are defined in "roadparts". The very best thing would be to get polygons around every roadpart which I could use on other data to bind it to the right road.
 
The only solution I can see is making a raster of small rektangels that I bind to my roadparts using nearest neighbour-calculations.
 
My question is if someone has a more efficient and better solution.
 
Sorry for my bad english
 
Thanks
