Google Maps: Traffic on top of Custom Map - google-maps

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.

Google Maps iOS custom UIView instead of a marker

I'm looking for a way to use a custom UIView (not just a custom image) instead of default marker provided by Google Maps iOS SDK. Basically I need a possibility to place my UIView agains proper coordinates of the map, so not necessarily to use markers as they are, just any suitable solution. Any ideas?
There is not currently a way to do this. You can view the relevent feature request (and star it, to show interest) here: https://code.google.com/p/gmaps-api-issues/issues/detail?id=5203
The marker only shows an image. So it cannot take a CustomView. Moreover, if your custom view has some sort of button on it there is no way you can track the events from those button.
In simple words the map renders the markers as UIImage.

Showing information on Google Maps API

I'm fairly new to working with Google Maps API. When embedding a map you get the place and a white box in the top right hand corner with a little information on the place. However I want to use the JavaScript API and want to know is there anyway to replicate this with the JavaScript API and not the iframe embed.
Thanks.
Basically to display the information you would need to use the infoWindow, yes. You can attach an infoWindow to either a marker or directly to map co-ordinates. In depth documentation about infoWindow and detailed references can be found here.

Google map API v3 markers overlapping

I am making an application with google maps.
When markers are overlapping only the last one is displayed even if the icons are different..
I do not want it to cluster in that case, rather it should show both maybe by changing the coordinates just a but??
Any solutions??
I think this is a pretty elegant solution, called Spiderfying the markers.
https://github.com/jawj/OverlappingMarkerSpiderfier
I'm thinking of using it.
What I do now is use JavaScript to make a fancy popup that hides and shows divs on one marker location (created problematically in PHP, but you could do it on JS too). It has the side benefit of allowing less markers on the map.
Click a black numbered marker on this map to see it in action.

Another option is to use Google Maps API 3 Utility Library, it has a Marker Clusterer.

Custom Google Map overlay?

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.

Web-based UI element for selecting a geographical location

I'd like to create / use a UI element for a web-site that provides a world map, on which the user can draw a circle to indicate an area of interest. I'd like information on the coordinates of the area covered by the circle to be available to me via Javascript for sending back to the server over Ajax.
Does such a control exist, and if not how difficult would this be to implement using something like Google Maps?
Google would have that as part of it's api as would OpenLayers
maybe Artem GoogleMap can help you.
