Where On The Map Am I?

When I blogged about using KMLMapLoader to load easily load KML/KMZ files onto a map I quietly side-stepped one problem. The KMLMapLoader requires you to specify the latitude and longitude on which to centre the map and a zoom level, but where do you get these values from?

You could play around with the main Google Maps page and try and figure out appropriate values but this can be a bit hit or miss. The easiest way it to use a new feature in TagME. Simply open your project, choose to configure Google Maps from the tools menu and then specify the size of the map (in pixels) and it will give you the latitude, longitude and zoom values to use. Nice and simple!
