Folks,
May I kindly ask for a bit of brainstorming about
available and programmatically callable,
optionally usable,
optionally effective,
optionally robust
solutions of remote routing services?
The use case is very simple:
1) client is a non-Web thin client
2) client has access to the Internet
3) client knows two locations "start" and "destination"
4) client wants to know how to travel from start to destination
What are available options to achieve that? Where if availability means:
* accessible for public
* free of charge
* does not require to sign anything,
Custom solutions built on OGC-enabled stack (e.g. PyWPS, etc.) is also
an option to discuss.
Any input greatly appreciated.
Best regards,
Mateusz,
Is the client looking for a solution that runs somewhere on the net that
they can make requests to, or are they looking to setup a server with
data and a routing engine?
I intentionally didn't write anything about that as an indicator that it
does not matter. I mean, both options arepossible.
I can install (almost) anything or I can use something that's ready now.
Certainly, the latter would be easier.
By the way, I use word "client" as "software client" but not as a person
or company who asked me to deliver solution.
Actually, I'm thinking about implementing and delivering something on my
own, as an Open Source Software. However, that's another story.
So I'll plug my infant and immature routing engine project:
http://sourceforge.net/projects/opengraphrouter/
Interesting. I will take a look. Of course I will, I've seen the "Boost"
stuff over there in SVN, hehe ;-)
Also pgRouting is an option.
I know about it but...data, bloody data!
The big issues in most cases will be data.
Yes.
Some people are doing routing with OpenStreetMap and pgRouting.
What are the results of OSM evaluation for routing purposes?
If they want accurate (ie: navigable
routes then they will probably need something based on Navteq or
TeleAtlas) or if they are look at a small county or state wide area then
they might be able to get data from the local governments like
http://www.mass.gov/mgis/mapping.htm
At this particular moment, I don't care about data.
It probably silly as any software without data is useless, but first I'm
interested in setting up some remote service (software) infrastructure
(a demo, a testbed) that will allow a *thin* client to exploit and
benefit of routing.
This could be tested using any data that are available.
If proved working, finding proper data would be next step.
Because good data is expensive and licensed, in most cases by
transactions, it is not likely that you will find services equivalent to
Google that are free.
I'm am an incurable dreamer but that incurable to aim to beat Google :-)
Best regards,
