To partly answer my own question, I think the author might have gotten the magic numbers from this article:

This is great. Could you add some explanation of how you came up with the values of the configuration items bbox and maxResolution?

I’ve found some docs:

Cr, two comments:
* The VETileSourceSpecification constructor (at least in v6.1 of the VE control) won’t take null for TileSource. An empty string will do though.
* 3D mode in VE does not support custom tile naming schemas. I’ll look into setting up tilecache to do standard VE tile naming. That way this can be used in VE 3D mode as well.

Some documentation available on how to generayte kml superoverlays?
Or maybe i need to look into the source code?

Diego:

TileCache 2.x has KML SuperOverlay support for layers in EPSG:4326. See http://openaerialmap.org/static/oam.kml for how to set it up.

Absolutely awesome!
It’s planned a support for Google Earth’s KML SuperOverlays with TileCache?
Gdal2Tiles support this behavior, but don’t support KML generation from WMS…

Rupert:

That is absolutely possible… and has been for quite a while already. http://openlayers.org/dev/examples/spherical-mercator.html does exactly that with no problems that I’m aware of.

Really interesting post… Not directly related to this post since its TC on top of GoogleMap/VE API..

But I wonder if it is now possible to do it with OpenLayers API (Google as BaseLayer) + Custom TileCache 900913 Road Overlay?

I’ve tried using speherical mercator on OpenLayers (Google as BaseLayer) + WMS 900913 Road Layer without any problems. Hoping TC to make significant performance improvements instead of using WMS as stated above.

Again thank you for making invaluable contributions to the internet GIS industry…
