Landsat 5 image from 25 Jan 2004 (path 94 row 78)

False-colour image of a patch of central Queensland near Charleville.

Bands displayed:

R: 5

G: 4

B: 2

With this choice of band display, fresh grass is usually bright green, trees dark green, and bare soil and dead, dry grass various shades of pink, magenta and buff. Blackish purple areas can be recent bushfire or recently ploughed dark soil.

 

If you compare two images from different dates using these bands, you can see a change from dark green to bright pink if someone has cleared a patch of woodland or forest. There was a lot of clearing going on in 2003, but in later years it has all-but stopped, due to stricter legislative control over clearance of native tree cover.

 

Landsat 5's orbit is 705 kilometres above the earth's surface, and each pixel in its Thematic Mapper imagery corresponds to a 30 x 30 metre square on the earth's surface.
