The next step for the surface mapping data is being exported to a KML file. KML has actually been an easy markup to understand. It’s structured similar to HTML, but has unique tags identifying various data formats and visual styles. I’ve posted links to the resources I’ve used at the bottom of the page. I just went through them in the order they are, the first page to learn what KML was capable of, then the second as an overview of the tags available to work with. After those two I found Google’s interactive sampler, which allows you to write your own KML and update it in a live environment. I’ve been working with the sampler to find the best way to get format the data, as it seems fully capable of rendering KML and is very convenient to have live control of your code.
