The ERS SAR image shows the central part of the Scottish Highlands between
the North Sea and the North Minch, belonging to the Atlantic Ocean. Between
these two extremes the North-West Highlands are stretched out. They include
different well-distinguishable types of morphology, especially comparing the
southwestern and the northern part of the image.
The heather vegetation of the
higher section of this landscape appears brighter, mainly because of the
bog-type structure of the soil and their high water content. The valley bottoms
are usually used as pasture and appear darker, as expected.
To the east the A9
highway crosses the scene. Its three bridges are best visible (enlargements). The
northernmost crosses the Dornoch Firth near Clashmore. Further south the Moray
Firth is imaged with a series of ships and moored structures visible as bright points. Inverness is
discernable south of the image centre (enlargement). Here too, the highway
bridge is clearly seen. In the upper left corner, the area around Loch Broom is
present. The bright appearance of the sea is not only due to the roughness,
i.e. of high winds, but is mainly due to the steep incidence angle of the radar
- at near range location. In contrast to this the waters of the inner part of
the Firth are smooth and therefore dark, independent from the incidence angle.
