You do not have to wait for all layers to display to continue zooming in, just click again.
The JavaScript coding is currently set to increase or decrease the scale by a factor of 3.
These are 'live' pages, assembled on the fly from the various WMS servers.
All servers are not mirrored and 'always' on-line.
For instance, the Sea Surface Temperature (sst_northeast) layer is made
from today's latest passes, and will not be there tomorrow.
The MODIS "daily_aqua" and "daily_terra" layers
are subsets of the latest daily passes.
Click the "Layers" link to see and modify the various layers included in your map.
The window may take a while to load. Layer names are determined at the server level.
Check "Auto" first, then make any changes.
At this point layers should appear or disappear when a checkbox is checked or unchecked.
Some servers are faster than others. Use some care as the small
"Layers" page must be closed before attempting to reopen it again.
Clicking "Previous" will go out one layer only. Contol-click will continue to go out.
Click "Full Extent" to return to the initial scale.
