A proposed streamflow data program for Michigan
P.C. Bent
1970, Open-File Report 70-25
An evaluation of the streamflow data available in Michigan was made to provide guidelines for planning future water resource programs. The basic steps in the evaluation procedure were (1) definition of the long-term goals of the streamflow data program in quantitative form, (2) examination and analysis of all available data...
Digital computer terrain mapping from multispectral data, and evaluation of proposed Earth Resources Technology Satellite (ERTS) data channels, Yellowstone National Park preliminary report
Harry Wynn Smedes, K. L. Pierce, Marc G. Tanguay, R.M. Hoffer
1970, Open-File Report 70-307
Digital computer processing of 12 wavelength bands of visible and reflective infrared scanner data has resulted in successful automatic computer mapping of eight terrain units in a Yellowstone National Park test site. Target areas in the scene were selected for training the computer. Statistical parameters of radiance such as mean,...
Geologic studies of Yellowstone National Park imagery using an electronic image enhancement system
Harry Wynn Smedes
1970, Open-File Report 70-306
This report describes the image enhancement system developed by the Philco-Ford Corporation; the kinds of enhancement attained; the results obtained from various kinds of remote-sensing imagery (mainly black and white multiband, color, color infrared, thermal infrared, and side-looking K-band radar) of parts of Yellowstone National Park; and possible additional fields...
Schmidt hammer test method for field determination of physical properties of zeolitized tuff
John R. Ege, Danny R. Miller, Walter Danilchik
1970, Open-File Report 70-117
The L-type Schmidt hammer is a hand-carried impact instrument that was originally designed and developed to test the compressive strength of concrete. When properly impacted against a stiff material the device measures the amount of rebound of a spring-loaded hammer, with the rebound of the hammer being directly proportional to...
Satellite relay telemetry of seismic data in earthquake prediction and control, 1968 and 1969
W. H. Jackson, Jerry P. Eaton
1970, Open-File Report 70-173
This report describes the progress of the Satellite Telemetry Earthquake Monitoring Program during the period 1 July 1968 through 30 June 1969. This research was supported by the National Aeronautics and Space Administration under Contract No. R-09-020-011, Task No. 160-75-01-50-10.The project was initiated in FY 1968 to evaluate the applicability...
Geologic map of the Arvada quadrangle, Colorado
Robert M. Lindvall
1970, Open-File Report 70-198
Many of the engineering-geologic problems in the Arvada quadrangle are related to the unconsolidated surficial deposits, which mantle the bedrock to depths of as much as 40 or 50 feet. In this report most of the emphasis is placed on the map distribution of these materials and on a description...
