Book excerpt: Photographic and infrared scanning surveys were made over Harper Lake, California, on three occasions during 1970 to evaluate the usefulness and limitations of aerial techniques for assessing ground conditions on dry lakebeds. The surficial geology of the lakebed was mapped and ground measurements were made for soil moisture, salt content, strength, and radiometric temperature. Infrared imagery in the wavelength region of from 1 to 5 micrometers is well-suited for detecting and mapping zones of soft or moist soils on playa surfaces, although spatial resolution is a limiting factor. The effects of surface soil conditions and micromorphological features on aircraft operations were also evaluated. (Author).
