Hello Friendly People, I'm trying to implement a map with a custom base map and a custom projection. I started from the code examples here http://code.google.com/apis/maps/documentation/javascript/maptypes.html and I'm trying to implement an Albers Equal Area Projection instead of the Gall Peters one. I'm using this formula to do it http://mathworld.wolfram.com/AlbersEqual-AreaConicProjection.html
The equations aren't coming out right though, and the functions aren't working properly as inverses of each other. When I do albers.fromPointToLatLng(albers.fromLatLngToPoint(new google.maps.LatLng(32, -80))) I get a LatLng where the longitude is right, but the latitude wrong. In the fromPointToLatLng function, its trying to take the arcsin of a number greater than one. I'm pretty sure I need to scale the results from the functions up and down to world coordinates but am not sure how to do it. My code here: http://albertsun.info/misc/maptype-base.html Any help would be much appreciated!
