From the announcement:
MoEML is excited to announce the launch of a beta version of our new hi-resolution, zoomable experimental Agas map interface.
We encourage you to play around with the map and send us feedback on both its function and design so we can improve it before launching it officially later this year. Some of you might like to read theInstructionsfound on the toolbar menu at the top of the page to orient yourself first. Others might prefer to jump right in and start experimenting!
