I have been asked to investigate methods for obtaining KML files. All I know so far is that it is a format based on XML that Google uses to format their maps (or the metadata). However, are there places or methods that I may avail myself of to download KML data without going through Google Earth? For example, is it possible to get the KML for the vector data of a state in the US (roads, boundaries, etc.) ?
To restate it simply: I want Google's vector data so I can plop it into ArcMap. Are there repositories for such things? I doubt it, since Google never struck me as being all handy dandy open source randy, but one can hope.
