Analysis Research For Earth Resource Information Systems: Where Do We Stand?, David A. Landgrebe

LARS Technical Reports

For a decade or more research has been conducted which is intended to lead to the design of operational earth resource information systems. Clearly this research has not yet been completed. It does seem to be far enough along however, that an assessment relevant to future operational activities might well be possible and beneficial. In this paper a model operational system will be discussed not so much as a proposal for an actual system, but merely as a viable objective upon which to focus the research. Possible system configurations and constraints will be noted, and the trend in the cost …

Machine Processing Methods For Earth Observational Data, D. A. Landgrebe, F. C. Billingsley, J. D. Nichols

LARS Technical Reports

A brief review of the development over the last decade of earth resource informations systems is presented. Machine data preprocessing and analysis methods are surveyed and illustrated. These include preprocessing steps intended to modify geometric and radiometric aspects of earth observational image data to enhance the ability of either human interpreters or machine algorithms to extract information from data. Illustrations of processed and analyzed images from spaceborne sensors including the Earth Resources Technology Satellite are discussed.

Automatic Boundary And Sample Classification Of Remotely Sensed Multispectral Data, R. L. Kettig, D. A. Landgrebe

LARS Technical Reports

Presently, automatic classification of multispectral data images is most commonly effected on a point-by-point basis, as if the data vectors from one resolution element to the next were uncorrelated. In other words, no use is made of the spatial information contained in the scene. This is a useful but suboptimal approach, since in a practical situation strong correlations are certain to exist. "Sample classification" is a name used to refer to those classification schemes in which points a reclassified in sets (samples) rather than individually. It is assumed that all the points in a set belong to the same class. …

A Result From Studies Of Transformed Divergence, Philip H. Swain

LARS Technical Reports

The purpose of this memorandum is simply to convey briefly and quickly to LARSYS users a result derived from some recent studies of the relation between transformed divergence and classification accuracy. These studies were carried out under the author's direction by Roger C. King, an undergraduate in Electrical Engineering. A detailed publication describing the investigation will be forthcoming shortly.

Urban Land-Use Mapping By Machine Processing Of Erts-1 Multi Spectral Data: A San Francisco Bay Area Example, Richard Ellefsen, Philip Swain, James Wray

LARS Technical Reports

Results are promising of an experiment to map land use in an urban area by automatic digital processing of ERTS-1 data. Computer-maps of a large segment of the San Francisco-Oakland and San Jose Urbanized Areas have been produced at a scale of 1:24,000 using a segment of an ERTS-1 frame reformatted to correct skewness and scale. An area of some 6,500 square kilometers was also mapped at 1:48,000 (a one-fourth sample). For both scales, urban areas were separated from rural -- using a photo interpretation procedure -- to solve problems of the spectral similarity of functionally different land uses and …

Mapping Soils, Crops, And Rangelands By Machine Analysis Of Multi-Temporal Erts-1 Data, M. F. Baumgardner, James A. Henderson

LARS Technical Reports

ERTS-1 data, obtained during the period 25 August 1972 to 5 September 1973 over a range of test sites in the Central United States, have been used for identifying and mapping differences in soil patterns, species and conditions of cultivated crops, and conditions of rangelands. Multispectral scanner data from multiple ERTS passes over certain test sites have provided the opportunity to study temporal changes in the scene.

Geometric correction was performed on the digital data for several dates and for several test sites. This made much easier the task of locating specific data points and of comparing the analytical results …

Weighting Function Techniques For Storage And Analysis Of Mass Remote Sensing Data, James R. Jancaitis, John L. Junkins

LARS Symposia

Recent publications have documented the development and successful application of weighting function techniques for analytically modeling discretely measurable two-dimensional irregular surfaces. The weighting function techniques produce an analytic functional model valid over the entire input data set. The globally valid function is comprised of an arbitrarily large family of locally valid functions which join together with m-th order continuity assured. The locally valid functions are typically low order polynomials, so that analysis of the functional model is efficient and inexpensive. The theory of the weighting function techniques has been extended to N-dimensional functions, allowing mathematical modeling of discretely measurable functions …

Basic Forest Cover Mapping Using Digitized Remote Sensor Data And Automatic Data Processing Techniques, M. E. Coggeshall, R. M. Hoffer

LARS Technical Reports

Increasing demands on the forest resource will necessitate increasingly more intensive management in the future. In order to achieve this goal, reliable and timely information over large geographic areas will be required. Remote sensing techniques offer much potential for the procurement of such information.

This research, then, was pointed toward study of that potential. Four objectives were established as follows: 1) to determine the optimum number of the available twelve multispectral scanner (MSS) wavelength bands to use for forest cover mapping with automatic data processing (ADP) techniques; 2) to determine the current capability to map basic forest cover using MSS …

The Corn Blight Watch Experiment: Economic Implications For Use Of Remote Sensing For Collecting Data On Major Crops, Jerry A. Sharples

LARS Technical Reports

The 1971 Corn Blight Watch (CBW) Experiment was the result of two major developments. One was the Southern corn leaf blight epidemic of 1970 and the concern about its return in 1971. The other was the need to test and evaluate the technological breakthroughs that had recently been made in remote sensing. In this paper I use the Corn Blight Watch experience to draw some implications for using remote sensing to collect data on major crops.
