So, I had in mind to create a website that contained a map of the SL grid with multiple points on it, and I found that there was such an API (http://secondlife.com/developers/mapapi/), but that it seems that it fell through the cracks back in September '07 (http://www.secondlifeinsider.com/2007/09/27/second-life-map-api-goes-missing/) in favor of integrating with the Google Maps API, used on the SLURL site (http://www.slurl.com).
However, as it was pointed out in the Second Life insider blog entry above, parts of the SL <--> Google interface script are not yet complete, specifically in the area of translating simulator names to points on the map. It looks like the SLURL.com scripting actually modifies the JavaScript snippet embedded in the page to shift the marker used to the right location, but doesnt' make public the means to translate sim names to data points.
So my question (for any Linden) is, when is the Google Map API scripting going to be complete? Is there anyone working on it?!
Alternately, is there a public listing of simulator names that correlates them to the grid positions used by the API? It looks like someone could go through manually with the example from the old system that's available at http://secondlife.com/developers/mapapi/locator-app.html and map them all out, but that looks like it would be some fair bit of tedium.
