Sky this Week

I’ve updated the Aurora add-on for NASA’s World Wind. The recently released (Feb 14) version 1.4 of World Wind now monitors cache files and updates them if they are expired. The Aurora add-on needed only a minor change to expire the cache so it will retrieve the current Auroral PMAps from NOAA National Weather Service Space Environment Center. You can download the updated plugin from http://www.sec.noaa.gov/pmap/GEpmap/

This works although the Earth/LayerSet.xsd that comes with WW-1.4 should technically disallow the markup within an ImageLayer. Apparently the LayerSet.xsd is not current.
