New Perl Module: Calculate Google Tiles

USNaviguide has just released a new Perl module (USNaviguide_Google_Tiles.pm) that calculates just about everything you'd want to know about tiles including:

Tile name for a coordinate (lat,lng)
Tile name for a pixel location (x,y)
Tiles for a bounding box of coordinates and zoom
Bounding box for a tile in coordinates
Bounding box for a tile in pixel locations
Coordinates to pixel
Pixel to coordinates
and a bunch of other stuff...

New Javascript Class: ProjectedOverlay

USNaviguide has just released a new Javascript class that works like GGroundOverlay in the Google Maps API except it doesn't attempt to stretch the overlaid image into the Mercator projection. This results in faster response and more predicable results.

Here's a demo of this class in action:
