I am working with google maps in flash, and i would like to know how to serve up my own image tile for the "we have no imagery at this zoom level..." error.
I dont want to serve up an entire map of images - just for the times when google has no image
does the tile layer base dispatch an event? (i couldnt find any in the api)
is there a method that can be overridden by extending the tilelayerbase class
any help appreciated

I'm pretty sure this does what you need ^ ?

I have developed an iOS application that allows the user to drag a GMSOverlay subclass around in the Google Maps SDK. The overlay scales with the map as the user zooms in and out.
I want to replicate this in the browser but can't find examples of how to do it. Today I happened to see a web page where this was done.
Draggable overlay example
If anyone has any ideas about how this is achieved (generally speaking - I will research from there) it would be appreciated!
The Google Maps API zoom_changed event and getZoom() method will let you track changes in zoom, which can be used to scale DOM elements.
So, i have custom route on my map. I put in on my web (local page to be precise). Unfortuently, on high dpi screen texts are very tiny. I've found static maps to be able to rescale map (https://developers.google.com/maps/documentation/static-maps/intro) but have no idea how to show my custom route on static map (route was generated from GPX file).
Is there any way to do it?
Regards!
So, after few hours of research i've found that i need to convert gps coords into polyline, ie. https://www.daftlogic.com/projects-online-csv-polyline-encoder.htm
It generates example link for google maps.
I have an application that downloads static images off Google maps, with markers placed where I want them (Placed by passing arguments into the Google Static Maps URL). However, I also need to be able to click the markers. I figured I could convert the x and y coordinate is the click to lon/lat, and then figure out that way which marker was clicked, but I haven't found that too easy.
I know the dimensions of the map in pixels, the zoom level, and the centre point of the map in pixels and lon/lat, so I followed this blog post. Unfortunately this didn't work.
Does anyone know how I could do this, or know another way I could figure out if a marker has been clicked? I'm forced to use the Static maps unfortunately, so I can't do any of it with the JavaScript API

It is not exactly what you are doing but it does demonstrate Mercator projection conversions & cross-browser mouse events.
So basically what i'm trying to achieve is this functionality in google maps v3,that they have in openlayers: http://dev.openlayers.org/releases/OpenLayers-2.11/examples/image-layer.html
Hide the base layer of googlemaps (the actual map), and then add a image overlay that is placed over the entire surface of the map.
Is this possible? and do anyone have any solutions at hand?
It's called a GroundOverlay: https://developers.google.com/maps/documentation/javascript/reference#GroundOverlay
However, while a GroundOverlay covers the base map, it does not remove it. You'd need a custom map type for that: https://developers.google.com/maps/documentation/javascript/maptypes#CustomMapTypes
It would be fairly easy to develop a custom map type that always returns a blank tile.
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.
