Explanations for ETM-subsets

This image is a subset of a Landsat 7 ETM+ image, covering a size of about 30 km by 25 km, which was acquired during the rainy season. It is visualized as a so-called false colour composite. On the Red, Green and Blue channels the spectral bands 4: NIR (near Infrared), 5: MIR1 (Mid Infrared 1) and 3: visible red of the Landsat ETM+ sensor are displayed (RGB: 4-5-3).This band combination suits best for a detailed visualization of different land cover properties. Due to that, the displayed colours are not natural.

Observatory	Claratal (S38)
Info	In the displayed image the observatory is given as a dotted rectangular box of 1km x 1km extension.
WRS2 Path-Row	178-76
Acquisition Date	17.05.2000
Image Details	The undulating landscape around the Claratal observatory is covered by a mixed grass / shrub vegetation. Reddish colours indicate higher bush density; greenish colours refer to higher grass coverage. Black and blue spots are lakes and artificial dams.

• Dark Blue: Water bodies, dams and lakes without Algae.
• Light Blue: in populated places mainly buildings, outside of towns mainly rocks, and very sparsely vegetated soils.
• Red: Very dense and vital vegetation like bush thickets, forests or planted fields, in towns: gardens.
• Green: "middle dense" or less vital vegetation, like grass savanna (light green) and dry bush (dark green).
• White: bare soil or sparsely vegetated areas, independently from the natural soil colour, also gravel roads and pads.
• Intermediate colours are representing mixed pixels with information of several land cover types.
