Hi,<br><br>I have been using PostGIS for a while and it works great for my requirement. I have roads & streets as shapefile and now, I wanted to a find the shortest route between locations.<br><br>I found pgRouting during the search process. There they talk about topology. They have suggested to use 3 tools for creating data for pgRouting and I don't have access to 2 of them. The one that is familiar to me is PostGIS. I intalled the topology functions and I am struck without any direction. Now what ?
<br><br>I request any one of you help me and I would greatly appreciate.<br><br>I have shapefiles of roads and how do I create data for pgRouting ?<br><br>Thanks<br>Green<br>
