Abstract:
A preliminary study of the Tazirbu region of Libya using color-processed, LANDSAT 1:250,000-scale imagery has produced a practical and potentially useful map of soils in a 10,000-sq km tract. Soil types were mapped by tonal differentiation and substantiated by ground samples where available. The map may help delineate changes in the clay/silt fraction of the sandy soils that dominate the surface of the area. Anomalous color keys characterize vegetation of sufficient density to be registered by imagery. Wind direction represents a prime investigative and interpretive tool. Land-use planning, now being undertaken by the Libyan government, can be simplified by restricting the initial reconnaissance
