Notes

(a)

You normally start with a whole-world overview image at 64Km (shown) or 32Km (1251x542 pixels scrolling) resolution.

(b)

HyperLens® Lenses extend the familiar concept of Layers. They are loaded using the Layers menu, and controlled using the lens buttons (on/off toggle) and the tabs (move/resize).

(c)

The AVHRR Browse Archive contains a total of 930 Global AVHRR satellite data products. This lens shows a fragment from one of them.

(d)

Six Land Classification data products are included. Each of these offers an interactive colourmap editor.

(e)

The underlying image is a global composite made from NDVI data. The NDVI lens is a filter, showing a greyscale image without colourmap.

(f)

The Query lens enables you to extract a scene at high resolution (1Km - 16Km). This fragment shows the south-west tip of England, including WebÞing's R&D office, with lenses open on fragments from the NDVI band and the IGBP Land Classification product.

(g)

The geographic coordinates follow the cursor whenever it is over the scene. Distances are also shown if you drag the mouse.
