Hi I'm in need of some guidelines and not asking for an specific error. Hope that's ok.
I'm working in a new website that will provide traffic info for the motorways of an area which is not covered by Google Maps Traffic. That website will be public and free of charge. And in fact it will replace a website that already provides this kind of info (and is widely used) over a different platform that we'd like to change to Google Maps (it being widely known and being easy to use and update). So I guess that's not a problem with the TOS (correct me if I'm wrong here and I need to get a licence please). Some of the info will mean painting the motorways with different color depending on the density/speed of the traffic. At first I wasn't sure on how to draw a polyline over the motorways on the GMaps for which we'll provide the info. Now, with the GDirections, I've been able to draw a polyline that suits me nicely (that meaning a polyline inside the motorway on the map). But I have some questions about how to draw all the lines I need in an efficient way. First of all, I'll get you the approximate amount of directions/ polylines I need: - I need to provide info for 7 different motorways. - Each motorway will be segmented (between 5 to 15 segments each). - I need to paint each segment in an appropiate color depending on it's traffic density/speed. So, I guess all in all there will be between 100-150 segments (the exact segments have yet to be defined). So, drawing those 100 or more polylines have some implications. And as I know before hand what the polylines will be, I am thinking on how to do it in the most eficient and easy way, so that it doesn't wastes Google resources and loads fast enough. So, how do I do that?????? Any reccomendations??? There goes a bunch of questions I've been thinking about: - Shall I'll get 2 GDirections for each motorway (north and south) with multiple waypoints for the segments and draw the 14 GDirections on the maps? That will imply calculating them every time even though I know them before hand. And I guess calculating 14 GDirections will be quite a waste of resources. If I do that, can I color each segment in a different color? (a GDirection with 2 waypoints equal 3 segments, which equals up to 3 possible different colors). - I've seen that there's a way to store a GDirection polyline. So. Shall I'll do those 14 GDirections on a test site (maybe one at a time to make things easier), obtain the polyline, store it somehow, and then on the final site just draw the stored polylines? If so, would it be faster if I encode the obtained polyline and then I always work with the encoded one? - Another question in relation with storing the polylines is about the segments (the steps between waypoints). I need to get the one hundred different segments, so, shall I store the 100 segments in 100 different polylines? Can I store the segments of a GDirection with various Waypoints in different polylines? Or shall my test page do a 100 directions and store all of them independently?? Resuming this up: I've got to paint some 100-150 polylines in different colors. The polylines will be drawn exactly over the motorways, so GDirections gets the polyline perfectly. As the polylines/directions are known before hand, I want to know how to do it as fast as possible (in all likelyhoods that will mean storing the 100 polylines extracted from GDirections before hand and working directly with them). Any guiding lines from an experienced GMaps developer will be highly appreciated!
