CharlevilleCharlevilleThis scene is located north of the town of Charleville and shows the change over the period 1972 to 1988. The Difference FCC image is very colourful, indicating a great deal of landcover change. Eyeballing all three images, the different landcover types can be distinguished. In the north, there are extensive areas of Mitchell grassland (Astrebla species) growing on cracking clay soils. This landcover type has a distinctive signature. The remainder of the scene is covered by Acacia woodlands, the mulga country
Setting aside the eye catching changes in greenness in the Mitchell grasslands, the Difference FCC image shows up two types of significant landcover change. The first is the small irregularly shaped areas of cover loss in the drainage lines that we can interpret as the consequence of grazing. The second and far more extensive areas have regular boundaries, and are areas where the woodlands have been cleared by mechanical methods to encourage the regrowth of grass.

Three rivers traverse the image; the Langlo (LHS), the Ward and the Warrego (RHS). Two distinct types of country are present that are better appreciated in the later FCC. The mulga (Acacia aneura) woodlands, which occupy most of the image, and the Mitchell grasslands with the gunmetal blue signature of dry grass on clay soils.
