Google Earth mashup: rain radar overlays
I previously wrote about my first attempt at a Google Earth (GE) “mashup” where I’d overlaid a Bureau of Meteorology rain radar image over a panel from Google Earth.
I’ve now modified the mashup to overlay two rain radar images side-by-side. I’ve taken the Grafton and Moree images and overlaid them over their respective ground areas. Writing the KML code was trivial; most of the time required to do this was in manually registering (aligning) the radar image over the ground area. while it’s not perfect, it’s adequate for my purposes.
To view and manipulate my mashup, download the KML file, save it to disk, then double-click it (or “open� it directly from GE).
Here’s what it should look like:
It might take a while to actually see some rain on this image – we don’t get all that much at this time of year.
