Re: Routing website using Gosmore routing engine

I would be disappointed if we implement Netherlands-specific code. gosmore is ready to be used on the whole planet file : It takes 3 hours to import it on a dual core 64 bit machine with 2 GB RAM and generates a 6.5 GB file.

I tried that yesterday but Gosmore choked on our sponsored 32 bit machine while processing a planet file from April 16th. The person that maintains the system claims that 32 bit in theory doesn't mean that it won't be able to process the planet. I assume Gosmore uses architecture specific variable types like 'int'?

Predicting the travel distance with OSM will always be inaccurate, because we don't have height data (as mentioned), DGPS wasn't used, people don't drive, cycle or walk down the middle of the road, OSM is out of date and the users don't always connect the ways. And people want travel time...

Yeah ppl always want more but, before we venture into the advanced routing areas, I want to get basic routing functional and available. Let's worry about exact traveltimes determined by combining the measured speeds of mobile phones, wifi networks and historic gpx logs later.

I can make gosmore output the names of the ways (1 per segment). So then it will be helpful if we know weather each turn is left or right (e.g. by calculating bearing), because then we can generate simple driving instructions.

That would be my next request for Gosmore. It would be great if you could implement that 🙂 I promise to put it to good use on the website 😄
