| | | | | | | Bardia Region Overview - Image processing - Part 4
This exercise is divided into eight parts and requires the use of LEOWorks.
False colour combinations increase the interpretability of satellite images. In false colour combinations, at least one infrared channel is used. The infrared light is not visible to the human eye but reveals a high and differentiated degree of reflected and emitted radiation. The infrared channel increases the interpretability of vegetation, because green vegetation reflects more in the near infrared than in the visible range of the electromagnetic spectrum. Infrared channels are useful to assess the health status of plants.
Open:
- Bardia_Landsat_2002_Band_4.tif
- Bardia_Landsat_2002_Band_5.tif
- Bardia_Landsat_2002_Band_3.tif
Combine them into a colour image with band 4 in red, band 5 in green, and band 3 in blue.
1. Compare false colour images with true colour images and describe how the colours change in general. Why does the forest appear in dark red and the rivers in blue?
2. Point to the Karnali bridge and the other features you have studied in the natural colour image. Are you able to identify and categorise different types of forest in the park?
3. Describe the image by dividing land cover into five groups: forest, grass lands, agricultural lands, rivers and river beds. Discuss the pros and cons of working with false colour infrared images with respect to natural colour images.
