Links: Load KMZ files on handheld Garmin devices, video of NASA rocket crashing into the moon

KMZ in a Garmin deviceGarmin has quietly released a pretty cool beta update for some of their devices; the Colorado, Oregon and Dakota, specifically. This update allows users to create image overlays in Google Earth, then load the resulting KMZ file on their device. Once loaded, the overlay will simply appear as part of the map when they view that area.
The instructions are pretty straightforward for anyone that has built an image overlay before. Simply build the overlay, save it your PC, and upload it to your device. It looks quite slick. Hopefully more devices and services will start supporting the KML/KMZ format, making the datasets in Google Earth even more useful.
Rich and Scott have both posted blog entries with tips on doing this with your Garmin. Rich covers some best practices for creating these maps to keep redraws to a minimum, while Scott gives a step-by-step walkthrough, along with a resolution chart to keep things looking sharp on your device.

Also today, as you may have heard, NASA intentionally crashed a segment of a rocket into the moon to study the impact. Keir has built a simple page that lets you browse the moon, the Cabeus Crater where the impact occured, and view a video of the impact as an overlay on top of the moon.
You can read more about the mission on the NASA website, or view the video below for a raw look at the impact:
