Abstract	Valuable gravel deposits adjacent to population centers are in danger of being lost to urbanization. Detailed exploration is needed to locate (within a large body of coarse-grained sediments) those gravel-rich sites of sufficient size and quality which yield profitable gravel extractions. Remote sensing provides a reasonably detailed means for rapidly exploring large areas. Satellite imagery (previously ERTS and now LANDSAT) can be used to study large areas of the land surface. Applying surface-materials-mapping techniques, those areas with good drainage (coarse textured soils) can be discerned from those which are more poorly drained. Spectral response of the surface materials in the visible and near infrared portion can be used to subdivide the scene into various categories of materials.
Supplemental Information	This paper was presented at the 27th Annual Highway Geology Symposium May 1976 in Orlando, Florida.
