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 Paulshoek (S24)
Info In the displayed image the observatory is given as a dotted rectangular box of 1km x 1km extension.
WRS2 Path-Row 176-81
Acquisition Date 23.08.2000
Image Details The Kamiesberg Mountains in the Namaqualand are covered by more or less dense bush vegetation (green). At the Paulshoek observatory (orange), the vegetation cover is more open than on the Farm Rooiwal (yellow observatory, South of paulshoek observatory). This fence line contrast is visible on the satellite image. Along river beds or water courses vegetation is very vital (red) at the satellite image’s acquisition date. In the North-Eeastern edge the relief is more flat, and vegetation changes to grass lands (pink and bright green) can be recognized.
In general, the colours refer to the following land cover types:
  • 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.
