<div dir="ltr">Hello, Daniel.<div><br></div><div>Thank you for your quick reply. Well, for now I wouldn't want to enrol myself in such an endeavor :) . I would prefer to use something that is already done, even if it is much simpler than other routing engines' driving instructions.</div>
<div>I was reading one thread of your mailing list where you guys talk about the solution presented by Stephen Woodbridge, using iMapTools, and I was wondering if Stephen's algorithm is accessible for use, or if it is a private solution.</div>
<div><br></div><div>Do you know anything about this subject? Thank you very much.</div><div><br></div><div>Regards,</div><div><br></div><div>Paulo.</div></div><div class="gmail_extra"><br><br><div class="gmail_quote">2013/11/28 Daniel Kastl <span dir="ltr"><<a href="mailto:daniel@georepublic.de" target="_blank">daniel@georepublic.de</a>></span><br>

<div><br></div><div>This offers me other types of functionalities that normal routing engines don't.</div><div><br></div><div>Even so, I need a higher-level functionality, namely route instructions or navigation directions, that pgRouting does not provide for now (I think).</div>
<div><br></div><div>I read some forum posts from people that had the same problem as me. Some of them are really old (more than 2 years). I found two ways of doing that:</div><div><br></div><div> - One way is to implement a instruction algorithm, such as the one described here: <a href="http://lists.osgeo.org/pipermail/pgrouting-users/2011-January/000537.html" target="_blank">http://lists.osgeo.org/pipermail/pgrouting-users/2011-January/000537.html</a></div>
<div><br></div><div> - The other way is to have an external service to do that, such as, <a href="http://techbase.kde.org/Projects/Marble/RoutingInstructions" target="_blank">http://techbase.kde.org/Projects/Marble/RoutingInstructions</a></div>
<div><br></div><div>Now, my question is that neither one of the approaches to having navigation directions from a pgRouting route is optimized or well documented. </div><div><br></div><div>Are there any new alternatives to these two approaches? If not, is there a more developed solution to the route instructions issue (commonly called Driving Directions issue) ?</div>

<div>I think the reason, why there is no out-of-the-box solution yet, is, that it is very difficult (probably impossible) to provide this kind of driving instructions in a way that it works for any (road) network.</div><div>
And beside the variety of data there are also lots of languages.</div><div><br></div><div>If you (or someone else) is able to draft a concept how to produce driving directions in a smart way, that it does not depend on a specific dataset or language, then such a functionality would be a valuable contribution ... which might even attract some funding ;)</div>
