Geometric Correction Of Erts-1 Digital Multispectral Scanner Data, Paul E. Anuta

LARS Technical Reports

ERTS-1 Multispectral Scanner Data is received from the satellite by NASA, processed, and delivered to users recorded on computer compatible tape and in photographic form. The computer tape form of the data is calibrated and line length adjusted by NASA but no geometric corrections are applied. The system-corrected photographic products are corrected for many geometric distortions including earth rotation effects in addition to the above two corrections. Also, these images are rescaled so that the horizontal and vertical scales are the same. Thus, the digital form of the MSS data contains many geometric distortions and users of this data are …

Machine Processing For Remotely Acquired Data, D. A. Landgrebe

LARS Technical Reports

This paper is a general discussion of earth resources information systems which utilize airborne and spaceborne sensors. It points out that information may be derived by sensing and analyzing the spectral, spatial and temporal variations of electromagnetic fields emanating from the earth surface. After giving an overview system organization, the two broad categories of system types are discussed. These are systems in which high quality imagery is essential and those more numerically oriented. Sensors are also discussed with this categorization of systems in mind.

The multispectral approach and pattern recognition are described as an example data analysis procedure for numerically-oriented …

Geometric Aspects In Digital Analysis Of Multi-Spectral Scanner (Mss) Data, Edward M. Mikhail, James R. Baker

LARS Technical Reports

Present automated systems of interpretation which apply pattern recognition techniques on MSS data do not fully consider the geometry of the acquisition system. Metric information cannot therefore be extracted from the data at the same time that interpretation is performed. In an effort to improve the usefulness of the MSS data when digitally treated, geometric aspects are analyzed and discussed. Attempts to correct for scanner instabilities in position and orientation by affine and polynomial transformations, as well as by modified collinearity equations are described. Methods of accounting for panoramic and relief effects are also discussed. It is anticipated that reliable …

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 …

Recognition Of Surface Lithologic And Topographic Patterns In Southwest Colorado With Adp Techniques, Wilton N. Melhorn, Scott Sinnock

LARS Technical Reports

Analysis of ERTS-1 multispectral data by automatic pattern recognition procedures is applicable toward grappling with current and future resource stresses by providing a means for refining existing geologic maps. The procedures used in the current analysis already yield encouraging results toward the eventual machine recognition of extensive surface lithologic and topographic patterns. Automatic mapping of a series of hogbacks, strike valleys, and alluvial surfaces along the northwest flank of the San Juan Basin in Colorado can be obtained by minimal man-machine interaction. The determination of causes for separable spectral signatures is dependent upon extensive correlation of micro- and macro field …

An Analysis Of Milwaukee County Land Use By Machine-Processing Of Erts Data, W. Todd, P. Mausel, M. F. Baumgardner

LARS Technical Reports

The identification and classification of urban and suburban phenomena through analysis of remotely-acquired sensor data can provide information of great potential value to many regional analysts. Such classifications, particularly those using spectral data obtained from satellites such as the first Earth Resources Technology Satellite (ERTS-1) orbited by NASA, allow rapid, frequent and accurate general land use inventories that are of value in many types of spatial analyses. In this study, Milwaukee County, Wisconsin was classified into several broad land use categories on the basis of computer analysis of four bands of ERTS spectral data (ERTS Frame Number

E1017-16093). Categories identified …

Spectral Mapping Of Soil Organic Matter, S. J. Kristof, M. F. Baumgardner, C. J. Johannsen

LARS Technical Reports

Multispectral remote sensing data were examined for use in the mapping of soil organic matter content. Computer-implemented pattern recognition techniques were used to analyze data collected in May 1969 and May 1970 by an airborne multispectral scanner over a 40-km flightline. Two fields within the flightline were selected for intensive study. Approximately 400 surface soil samples from these fields were obtained for organic matter analysis. The analytical data were used as training sets for computer implemented analysis of the spectral data. It was found that within the geographical limitations included in this study, multispectral data and automatic data processing techniques …
