font-family:Arial'><span style='mso-spacerun:yes'> </span>I have a question
related with using pgdijkstra module. The module calculates optimized path node
by node. My network is a transportation network, if I have a point somewhere in
the area, for example, it can be a car’s location from GPS, and the point
is not on any edges of the network. What is the quick method to match the point
to a node in the network?<span style='mso-spacerun:yes'> </span>Are there any
examples somewhere? How does Cartoweb demo match city to a node in its transportation
network? I can search the nodes and find the closest one by specifying a
searching distance (for example, starting with 100 meters, then increasing by
10 meters if no node find, and giving up is the searching distance reaches
1000). Thanks in advance.<o:p></o:p></span></font></p>
