In tutorial 1.6, there is an access to jpl: http://wms.jpl.nasa.gov/wms.cgi?REQUEST=map&LAYERS=us_landsat7&STYLES=&FORMAT=png&TRANSPARENT=true The image in the tutorial wont show up. When I put it in my browser, it returns: <WMTException version="0.1">No bounding box (bbox) specified!</WMTException> Not sure if it is a bug. Changqing
