Minimum Distance Classification In Remote Sensing, A. G. Wacker, D. A. Landgrebe Jan 1972

Minimum Distance Classification In Remote Sensing, A. G. Wacker, D. A. Landgrebe

LARS Technical Reports

The utilization of minimum distance classification methods in remote sensing problems, such as crop species identification, is considered. Minimum distance classifiers belong to a family of classifiers referred to as sample classifiers. In such classifiers the items that are classified are groups of measurement vectors (e.g. all measurement vectors from an agricultural field), rather than individual vectors as in more conventional vector classifiers.

Specifically in minimum distance classification a sample (i.e. group of vectors) is classified into the class whose known or estimated distribution most closely resembles the estimated distribution of the sample to be classified. The measure of resemblance …


An Early Analysis Of Erts-1 Data, D. A. Landgrebe, R. M. Hoffer, F. E. Goodrick Jan 1972

An Early Analysis Of Erts-1 Data, D. A. Landgrebe, R. M. Hoffer, F. E. Goodrick

LARS Technical Reports

ERTS-A was successfully launched to become ERTS-l on July 23, 1972. The sensors on board were utilized to collect image data over the U.S. for the first time two days l a t e r on Tuesday, July 25. An early analysis of a data set was conducted at Purdue/LARS in order to arrive at preliminary indications as quickly as possible about the operating characteristics and potential value of this satellite as a data gathering device.

To this end a black and white image of channel 5 data together with tapes from the multispectral scanner was made available to Purdue …

Results Of The 1971 Corn Blight Watch Experiment, Robert B. Macdonald, Marvin E. Bauer, Richard D. Allen, Joseph W. Clifton, Jon D. Erickson, David A. Landgrebe

LARS Technical Reports

A serious and unexpected epiphytotic of southern corn leaf blight reduced the nation's corn crop by 15 percent as a new race of this previously minor disease swept through the Southern and Corn Belt states during July and August, 1970. The disease appeared so suddenly and moved with such speed that accurate information on its extent and severity was not compiled until well after the end of the growing season.

Research by the Laboratory for Applications of Remote Sensing (LARS) in 1970 had shown that three stages of blight infection could be accurately classified from small scale color infrared photography …


Land Utilization And Water Resource Inventories Over Extended Test Sites, Roger M. Hoffer Jan 1972

Land Utilization And Water Resource Inventories Over Extended Test Sites, Roger M. Hoffer

LARS Technical Reports

During the past decade, many actual and potential applications for remote sensing technology have been determined. This past year has seen a tremendous amount of interest generated in the application of remote sensing to problem related to land-use. A key element in applying remote sensing to land-use studies involves accurate identification of basic and vegetative cover types. In work with automatic data processing (UP) techniques it is found that as information requirements become more specific, the analysis task becomes more complex. In dealing with many problems involving automatic mapping of vegetative cover types conditions, one finds that an analysis sequence …

A Cluster-Oriented Analysis Of Multispectral Scanner Data, Paul E. Anuta Jan 1972

A Cluster-Oriented Analysis Of Multispectral Scanner Data, Paul E. Anuta

LARS Technical Reports

The standard procedure at LARS for classification analysis of aircraft scanner data has been to training samples (fields) based on the ground truth data and to use these directly or in a form subdivided via clustering as training for the computer. In this process the major emphasis is on defining class statistics which describe actual materials of interest as designated by the user. The approach assumes these materials are spectrally separable and classification is performed to test if this is true. In the approach described here the multispectral data is first clustered to determine what spectrally separable groups exist in …


A Three-Stage Sample Model For Remote Sensing Applications, Ludwig M. Eisgruber Jan 1972

A Three-Stage Sample Model For Remote Sensing Applications, Ludwig M. Eisgruber

LARS Technical Reports

Large-scale applications of remote sensing for the purpose of preparing crop estimates, natural resource inventories, disaster assessments, etc. for a given geographic region will, in general, involve questions of sampling, since complete coverage of the total geographic region and subsequent analysis of data collected with complete coverage appear technically and economically infeasible. This is true regardless of whether an aircraft, or a satellite is involved, and It applies equally to photography, multispectral measurements, radar, etc. Thus, even if remote sensing provided completely accurate data, estimates (of crop acreage, natural resources, extent of disaster, etc.) for the total region under study …


Engineering Soils Mapping From Multispectral Imagery Using Automatic Classification Techniques, Terry R. West Jan 1972

Engineering Soils Mapping From Multispectral Imagery Using Automatic Classification Techniques, Terry R. West

LARS Technical Reports

Multispectral imagery collected over southeastern Pennsylvania by Willow Run Laboratories, University of Michigan, was analyzed at the Laboratory for Applications of Remote Sensing (LARS) using its current capabilities for automatic classification. The project involved the evaluation of imagery in thirteen discrete bands of the spectrum as a source of data on engineering soils. Detailed computer classifications of two 4-mile segments of the Pennsylvania flightline, each containing predominantly one parent soil material, were obtained. Classification accuracy as measured by training field and test field performance was in excess of 90%. Using these two segments as a basis, a computer-implemented map was …
