[Google Maps API v3] Re: Drawing manager - Snap to road option
Hi Marcelo, Contrary to you I hope they do add this feature, and Google has no need to bloat the code as they have already started using libraries that can be loaded on request, so if you don't need the code, you don't load it. MymsMan question is non trivial and has it's applications in some scenarios, You can not really use the getdirection solution if you are implementing a solution that follow the GPS coordinate for an extended amount of time because doing so would lead to overuse of the getdirection quota of google. So the solution would be somehow to detect the nearest road once, somehow find the two extremity of the nearest straight length of that road and stick to it until an other road get nearer and do again a getdirection. First I don't even know if this is possible, and second, talk about bloated code in the web page. Would you have a better solution to this problem ?

All you need to do is to get directions between that last two points added and the routing engine will automatically return a point that is on the nearest road, which you can then use to modify the position of the marker and/or polyline. -- Marcelo -http://maps.forum.nu -- It would also be a useful option for polygons which are bounded by roads.

So the solution would be somehow to detect the nearest road once, somehow find the two extremity of the nearest straight length of that road and stick to it until an other road get nearer and do again a getdirection. Bear in mind that what you're asking for is please change my GPS track data and make some of it up I agree that that can sometimes be desireable for cosmetic reasons, but equally many folk won't want doctored and made-up data on their maps purporting to be a GPS track (which it isn't any more). As you say, implementing this yourself is quite feasible but could fall foul of Directions service limits and quotas. If Google were to implement the enhancement suggestion, the behind the scenes mechanism would have to be a very similar AJAX service - we might foresee Google applying limits to that use of their resources too, that would be reasonable for say a drawing tool given the speed of drawing by hand. 'Abusing' such a service by using it to _automatically_ prettify a GPS track log could then still fall foul of usage limits and not get you anywhere in the end. Just saying, be careful what you wish for. -- You received this message because you are subscribed to the Google Groups Google Maps JavaScript API v3 group.
