Show only 1 direction for Google Maps embed API - javascript

For a school project we are making an application that can track the location of a garbage truck.
To calculate the fastest direction for the truck we are using the Google Maps embed API, but there is one "problem". The API returns 3 optional directions but we only need one.
Is there an possibility to show only one direction, or do we need the JavaScript API of Google Maps then?
Thanks in advance.

I suggest using the Google Maps JavaScript API. I am using it for my website and it works like a charm, with many functionalities.

google maps offline: not tiles but javascript

I have an HTML (phonegap) application that uses Google Maps API to display a map with markers. I want this app to be used offline. I know that Google Maps tiles can't be used offline (because of its license). However, what I want to do is use the map interface without the tiles.
When online -> tiles and markers displayed.
When offline -> only markers displayed.
However, the js loading of Google maps is complex, and I haven't managed to cache it.
Thanks.
Caching google maps javascript is not allowed, that's because their payment system is based on how many times their javascript API are loaded by the users. One page refresh is equal to one google maps API call, and depending what kind of contract you made you just lost -1 from the total amount of API requests you have purchased.
How is Google Maps API for Business usage tracked and reported?
A single load of the Google Maps JavaScript API into a page. The
JavaScript API is reloaded every time a page that uses the API is
reloaded. User interactions with the map (eg. panning, zooming,
changing map types) do not generate more page views. Note however that
a page view is generated if the API is loaded into the page even if
the API is not then used to display a map.
See https://developers.google.com/maps/documentation/business/faq#pageview
You could, of course contact google and try to ask some tailored business solution for your needs. I am not 100% sure what kind of things they offer if you contact them directly. But although, your request is somewhat impossible to fill since those UI generation codes also resides inside that google maps API javascript which you need.
So I would suggest that if you only need google maps interface when offline, take a moment and implement something similar with HTML/CSS/ (and some JS).. markers you could draw on canvas or use normal img's and positioning. If you need to implement dragging and zooming - it would be little bit more difficult but not impossible with canvas or some other techniques. But that being said it would just be easier to keep app online, we all have internet :) ? Making 1on1 matching dummy offline UI against google maps would be really painful process, when we consider the fact that google maps UI also changes overtime, like in their upcoming versions.
You could use OpenStreetMaps instead, it can be used offline: http://wiki.openstreetmap.org/wiki/Offline_Openstreetmap

Update Google Directions on the fly

I am creating a mobile app using Phonegap, JQuery Mobile and Google Maps API V3. The mobile app will allow users to input a destination address and then using the Google Directions API, I will show them the navigation directions to arrive to their destination.
However, the application will also be marking on the map any roads closed due to construction or maintenance works. Is there a way so that if Google Directions shows the driver to go through a particular road where there are maintenance works I change the route for him to go through a different street? The road which will be closed will be marked by a map marker, so as such all I need to do is check if there is a marker and if so, update the route to go from a nearby road/side street.
I am quite new to this, and would be really glad if someone can point me to some tutorial or tell me how this can be done.
Thanks!
There is no option to the specified particular road though, you might be able to get alternative route from Google Direction API.
You should specify "provideRouteAlternatives" property when the code invokes DirectionsService.route() method.
Then Google will attempt to calculate another routes.
That is only available option that I have known.
provideRouteAlternatives property

Google Maps api custom tiles for fictional video game world

I want to use the Google Maps v3 api to generate an interactive Google Map interface that uses custom tiles for a map from a video game. The app needs to be able to zoom-in out and display the proper tiles for each zoom level as well.
I'm looking for some resources or a tutorial on how to accomplish this. The Google Maps v3 API appears to only discuss using custom tiles that lay on top of the normal Google Maps tiles. That wouldn't make sense in my application since my map is for a fictional world and wouldn't line up with anything in the real world maps. Perhaps I'm just not seeing what I need in the API guide...
Check out the ImageMapType class in the reference. There's a nifty example showing Moon tiles.
One of my favourite applications is The Internet map, the developer wrote a pretty sweet article on how it was developed.
You need to either cut up your custom game map image into the appropriate file/directory structure that makes integration into Maps API easy (here's an example using Photoshop and some example HTML/JS code). Or use a more friendly tool like TileMill, but this expects data in a standard spatial data format and you probably don't have your game map stored in such a format. If you can go that route, they also provide a Node.js-based server called TileServe that makes integration a cinch.
If you are expecting a boatload of traffic, then maybe look at Google Maps Engine to host your custom game map image directly in Google's infrastructure.

Add get directions link to InfoWindow Google maps V3

Back with another google maps V3 question.
Here’s the background; I now have a map populated by a number of markers with info windows and what I want to do is add a link in the info Window that when pressed opens another browser window with google maps directions info in it.
I'v read a number of tutorials including the one by Mike Williams but most of them are either written for V2 of the API or just plain don’t seem to work, so do any of you good people know of a good noob tutorial that can give me some idea how to do this?
Thanks in advance
If you're just trying to send folks to http://maps.google.com for a directions query, a URL like http://maps.google.com/maps?saddr=Start&daddr=end might work, but I don't think there's any official documentation on those URLs.
If you want to have directions as part of your application, you should probably take a look at some examples of the Direction Service in the JS API.

Google Maps - Batch Geocoding by Postal Code

I have a list of canadian postal codes that I want tobe able to map on google maps. SO far I have only found this site :
http://batchgeo.com/ | My Attempt and what I want - http://batchgeo.com/map/3b634fc7cbf942db14284c925ff8631b
How can I achieve the same on my own? Can someone share a script?
I'm not sure if you can do the circles like batchgeo- I've never seen that with google maps before. But you can certainly map out multiple places and drop pins on each place.
Check out google's Maps API, it has a lot in there to help you get started, and is all javascript.
have a look at the google maps v3 api for reverse geocoding. This should give you the needed information to place markers on the map
