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 Niko North (S08)
Info In the displayed image the observatory is given as a dotted rectangular box of 1km x 1km extension.
WRS2 Path-Row 177-78
Acquisition Date 30.04.2002
Image Details The two observatories at the Farm Niko are located at a shallow slope between the higher Kalkrand plateau at the East and the Schwarzkalk system at the West. The colour shift from white to black in the image is given by the different geology, which is covered only by sparse vegetation. At the calcrete Kalkrand plateau, vegetation (greenish) is concentrated on shallow doline depressions. At the geologically older Schwarzkalk calcrete formation, higher vegetation densities only appear along the crossing Fish River bed.
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.
