Linking Windows

There can be as many windows in a browser as required. Windows are very lightweight DHTML elements, and they can be minimized and overlaid with other windows. Two simultaneous windows are shown here, one with the elevation map, the other with satellite imagery.
They can be zoomed and panned independently
.
However, when the "link" button is pushed, both windows will display the same region of the earth
. All subsequent zoom
and pan
operations in each window are also executed in the other one.
De satellite image is the NASA "Blue Marble" image composite, taken from observation with the Moderate Resolution Image SpectroRadiometer (MODIS) in the second half of 2001. The most spectacular images come from deserts
or mountains
, especially when these are compared with the elevation maps from the same region
. Holland looks like it was just wrested from the sea
