Selected annotated bibliographies for image mapping : geometric registration, resampling, contrast enhancement, spatial filtering, and color calibration
B.K. Quirk
1985, Open-File Report 85-51
Many articles have been published in the image processing areas associated with image mapping, but no document has combined these references in a single publication. Image mapping is a new and dynamic field and a baseline document reviewing past research in the image processing areas associated with it needs to...
Documentation of a Regional Aquifer Simulation Model, RAQSIM, and a description of support programs applied in the Twin Platte-Middle Republican Study Area, Nebraska
R. E. Cady, J. M. Peckenpaugh
1985, Water-Resources Investigations Report 85-4168
RAQSIM, a generalized flow model of a groundwater system using finite-element methods, is documented to explain how it works and to demonstrate that it gives valid results. Three support programs that are used to compute recharge and discharge data required as input to RAQSIM are described. RAQSIM was developed to...

1985, Open-File Report 85-487
Ice velocity data are presented for the lower reach of Columbia Glacier, Alaska. The data span a 29 day period and contain 1,072 angle sightings from two survey stations to 22 markers placed on the ice surface, and 1,621 laser measurements of the distance to one of those markers (number...
Mineralogy of drill cores from Jabal Sa'id, Kingdom of Saudi Arabia
M.H. Staatz, I. K. Brownfield
1985, Open-File Report 85-12
The mineralogy of three drill cores from the apogranite at Jabal Sa'id was determined principally to identify those minerals containing rare earths, niobium, tantalum, thorium, zirconium, and tin. Heavy mineral studies of two other drill cores indicate that the deposit is enriched in rare earths. The principal rare earth minerals...
