Mapping of land use/land cover classes is important task to conserve natural resources and to put suitable management practices. Remote sensing techniques provide promising possibilities to map land use/land cover classes since remotely sensed data covers a large area with periodic synoptic view.
The Kingdom of Saudia Arabia contributed significantly to world date production. The Qassim region of central Saudia Arabia is considered as one of most famous producing area locally, regionally and internationally.
In this study Enhanced thematic satellite scene of path 168 and row 43 acquired on 28.08.1999 was used. Unsupervised classification approach was used. Three major land use/land cover classes were determined viz hilly area (1232566.06 ha), vegetated land (1663389.88 ha) and sand dunes (470068.08 ha). The vegetated land constitutes the first class, mainly the Wadis, and it is mainly devoted to dates production. Hilly unproductive areas constitute the second class. Finally, it is obvious that sand dunes cover a large proportion of the study area.
It is worth to mention that sand dunes surround the vegetated land, which in turn will lead to the loss of some of the productive lands through sand encroachment. This fact necessitates the adoption of suitable management practices to retard and, if possible, to stop sand encroachment.
