|
<p>This is a demonstration of using Tiled WorldWind layers.
|
|
WorldWind requires you to define a "LZTD" -- the 3rd param of the
|
|
constructor -- and the number of zoom levels it supports. When a
|
|
worldwind layer is not visible at a given tile level, and empty
|
|
tile is placed there instead. Note that the maxResolution of the
|
|
map times 512px, must be a multiple of a power of two different
|
|
from the LZTD -- in this case, .28125 * 512 is 144, which is 36*4,
|
|
and 2.25*64. This example has a 'Bathy' layer, visible as you zoom
|
|
out, and a 'landsat' layer, visible as you zoom in, both visible at
|
|
zoom level 6.</p>
