I have lots of slices of (non-geographical) data that I'm trying to
view via google maps. It basically breaks down into N 'maps', each
containing M 'layers'.
This sample shows basically what I want to do:
http://code.google.com/apis/maps/documentation/javascript/examples/map-simple.html
I can get it to switch between two different maps by providing two
custom MapTypes (much like the Map/Sattelite toggle in the sample),
but I can't figure out how to make it so I can toggle on and off an
additional overlay layer (like the 'terrain' checkbox).
The official docs vaguely mention this (
http://code.google.com/apis/maps/documentation/javascript/maptypes.html#MapTypeInterface
) but unfortunately the bit I'm after ('See Adding MapType Controls
below') is a dead link, and I can't find this bit of the
documentation.
Does anyone know where the documentation on how to control the drop-
down toggle boxes exists?
Thanks
If you are looking to have a particular overlay appear or disappear based on a checkbox, you can check out http://geojason.info/2010/overlay-map-management-with-google-maps-api-v3/.
However, that involves checkboxes that are not actually on the map. They need to go in a sidebar or above the map or whatever. If you are hoping to be able to add things to the control where the "terrain" and the "layer" checkbox appear, I don't think there's any hooks in Google Maps API v3 to do that. I'd be happy to be wrong, but I don't think it's simple and I would expect any solution that managed to accomplish it would be brittle.

Is there a way to insert the image overlay a layer below the streets but on top of the map background? The roads can be individually styled, so it should technically work, but I haven't been able to find the option for it.
The only lead I have found so far is this question: Google Maps API - Overlay Custom Roads
Which unfortunately doesn't really solve the problem of having to manually enter the street info.
I'm currently working on a custom map for a whole city and manually illustrate all the streets and enter the street names would take an enormous amount of time.
Any info would be very appreciated, thanks!
Try to check this documentation about Styled Maps. Styled maps allow you to customize the presentation of the standard Google base maps, changing the visual display of such elements as roads, parks, and built-up areas.
Here you can also find some sample code that you can use in your sample code.
Also you can find here the Styled Map Wizard.
Creating styles by hand and testing your code to see how they look is potentially time-consuming. Instead, you can use the Styled Map Wizard to set up the JSON for your map's styles. The wizard allows you to select features and their elements, apply operations to those features, and save the styles to JSON, which you can copy and paste into your application.
I've been searching an answer to this and the best i could find was here at stackoverflow, where someone explains how to insert a box of information inside the Google Maps but actually i would like to have that box side-by-side with my location.
Here is an example, just click at one of the green dots in the map, it will show you what i would like to have:

How can i do this? It even zooms in automatically! Wow, Google maps API V3 seems to be pretty awesome. This is cool too: goo.gl/WDMYmz . Not related though..
Thank you very much for all the help provided.
What you see there is a custom overlay , a implementation of the OverlayView-class
There are libraries for a convenient creation of such overlays, e.g. infobox. The zoom may be set via the setZoom-method of the map.
I have a building floor plan and I need to specify its position on top of google map.
I like the way this is done in Google Floor Plans app - screenshot(the right part with map) - but I cannot figure out how they made it! :)
What part in Google Maps API I should look at?
In short - I have an image (plan of floor), and need to show it on top of Google Map and be able to manipulate with it (changing dimensions on events).
I'm thinking you'll want to implement a custom overlay. That link provides the relevant instructions for doing so. Also, Google provides a simple example so you can see the result here. Is that sort of what you're going for?
#Cianan Sims: Well, sure, I want custom overlay, but how is the question :-)
Fortunately, Google published tool called Overlay Tiler, which does exactly what I wanted - georeferencing of the image.
How can you use a custom tileset/overlay on a Google map, like was done here:
http://www.philaplace.org
That is pretty cool, and I would like to experiment with this.
There are a couple different ways to do it. One way is to create a GTileLayer object and implement the getTileURL() to return the URL pointing to your tiles.
But first you'll need an image that's cut properly in the tile format. For starters, I'd recommend you look at MapTiler: http://www.maptiler.org/ It will cut images for you AND generate a GoogleMap with the overlay.
You'll want to look at Google's Overlays (especially Custom Overlays) and Custom Map Types documentation for Version 3 of their Maps API.
I want to add traffic information to my custom map. Currently I'm using a Tile Layer Overlay on my Google Map to display custom map tiles. When I try to add GTrafficOverlay to my map, my custom map tiles display above the traffic information. Is there any way to display the traffic above my GTileLayerOverlay?
(Using the JavaScript api)
You should be able to do this in V3. Take a look at this sample: http://code.google.com/apis/maps/documentation/v3/overlays.html#ImageMapTypes
I tried this out and wasn't able to find a solution to the problem. There is nothing in the GTrafficOverlayOptions and I couldn't find anything in the references about the z-order of this stuff. I have suspect that this isn't possible.
Would love to see an alternative answer showing that I am wrong.
