Development of photogrammetry in the U.S. Geological Survey
Morris M. Thompson
1958, Circular 218
Photogrammetry, the science or art of obtaining reliable measurements by means of photography, is now used extensively in topographic mapping. Precise photogrammetric plotting instruments now enable the map maker to extract from aerial photographs much.of the detailed information required for drawing the map that formerly was acquired by laborious ground...
Physical properties of salt, anhydrite and gypsum : preliminary report
Eugene C. Robertson, Richard A. Robie, Kenneth G. Books
1958, Trace Elements Memorandum 1048
This summary is the result of a search of the available literature. Emphasis is placed on the mechanical and calorimetric properties of salt; the measurements of elastic, thermal, magnetic, and mass properties of salt are merely tabulated. Under hydrostatic pressure < 1,000 kg/cm2 at room temperature, salt deforms plastically to...
Mineralogical applications of electron diffraction. 1. Theory and techniques
Malcolm Ross, C. L. Christ
1958, Trace Elements Investigations 597
The small wavelengths used in electron-diffraction experiments and the thinness of the crystals necessary for the transmission of the electron beam combine to require a somewhat different diffraction geometry for the interpretation of electron-diffraction patterns than is used in the interpretation of X-ray diffraction patterns. This geometry, based on the...
