Thanks! You're right. For any reason, I was thinking about epsg:3857 as a not projected CRS, what obviously isn't. Those coords are 4326, of course. Silly me!

comment min function not found compiling osrm
It makes sense. I finally used a Mac OS X machine with a 64bits kernel, and it worked. So, you're probably right.

I finally compiled OSRM in a Mac OS X machine. So, I didn't continue with this way. But I think DennisL found the problem. It makes sense.

comment Doubts about how pgRouting topology is built and how flexible it is
Yes, probably. But I think I have a better idea now, after reading the documentation and make a few tests. It seems that there's no automatic way of doing this. It's a question about how you define your data.

Happy to hear that. I hope you can use it.

About the different level intersections, I think it's explained here: goo.gl/ojGmuH

comment Doubts about how pgRouting topology is built and how flexible it is
Ok, many thanks. I just have one doubt, about the different level intersection: You say "you'll have to make sure that there are no nodes within the specified tolerance". But the point is I start with just a few lines, and I want pgr_createTopology that do the job, and create the necessary vertices to connect my network. I don't know anything about nodes. I just want to specify in some way: "Ey, do you see that point where those 2 lines cross? That's not an intersection. They're at different height. Please, don't create a node there". But I think the response is here goo.gl/ojGmuH

comment Doubts about how pgRouting topology is built and how flexible it is
Thanks for your responses. I just keep a doubt. About 1 and 2, my point is that I just start with a bunch of lines in my table. One per row. I guess pgr_createTopology works creating a node per each intersection between lines. So, it decides where the nodes are. And if I want to represent that two lines intersect at a different level, it shouldn't create a node at that point, because there's no real intersection (example: a bridge over a motorway). I don't think it can do it.

You're right. I've already changed, keeping the original questions at the end.

My 6 original questions have been summarized in a general one about topology. Title changed too.
