Working with Landsat images

For further analysis of the area under investigation, we will open another satellite image with a higher spatial resolution. Open the following images with LEOWorks:

khumbu_1.tif
khumbu_2.tif
khumbu_3.tif
khumbu_4.tif
khumbu_5.tif
khumbu_7.tif

These are single spectral bands of a subset of a Landsat TM satellite image. This satellite takes images of the same part of the Earth every 16 days, and does so for many years. This makes it a very interesting source of data for the comparison of images taken in different years (multitemporal analysis).

The Khumbu area in 3,2,1 band natural colour combination

1. Can you think of any specific use for multitemporal analysis?

2. How many bands does Landsat TM have? What colours do they represent?

3. Which spatial resolution do the bands have?
