California Desert Resource Inventory Using Multispectral Classification Of Digitally Mosaicked Landsat Frames, Nevin A. Bryant, Ronald G. Mcleod, Albert L. Zobrist, Hyrum B. Johnson

LARS Symposia

Time and budget constraints have precluded the use of conventional mapping techniques for the U.S. Bureau of Land Management to produce a comprehensive resource inventory of the California deserts region as mandated by the California Desert Conservation Act. A Landsat mosaic at full resolution for ten scenes over the California deserts region was used to provide a continuous data base for multispectral thematic classification. Procedures for adjustment of brightness values between frames and the digital mosaicking of the Landsat frames to standard map projections were developed for this task and are discussed.

The principle of transect sampling was adopted as …

Transfer Of Remote Sensing Computer Technology To The Developing World---Case Examples, Charles K. Paul

LARS Symposia

Computerized image processing represents a level of technology sufficiently advanced that the Agency for International Development (AID) has had years of problems attempting to set up the necessary equipment support. The theory of pattern recognition and various software algorithms, such as maximum likelihood, kth nearest neighbor, and supervised clustering, are difficult to teach to remote sensing resource managers and technicians with limited education in mathematics. Computer hardware is relatively complex and, in addition to requiring programming skills, both procedural level, as well as operating systems, also requires training in electronic "trouble-shooting" and computer maintenance to keep systems in operation.

Georgia's Operational Landsat Processing System, N. L. Faust, L. E. Jordan, B. Q. Rado

LARS Symposia

The State of Georgia and the Georgia Institute of Technology have created an exemplary relationship in the formation of a cohesive group for the analysis of Landsat data, its application to real world problems, and its inclusion in applications using geographic data base techniques. This group has evolved over a period of four to five years and lists as its accomplishments several successful demonstration projects using Landsat data, an operational Landsat classification of the entire State of Georgia using 60 classes, the integration of Landsat data into several geographic data bases for use in operational short and long range planning, …

Transformation Of Atmospheric And Solar Illumination Conditions On The Ccrs Image Analysis System, Francis J. Ahern, Philippe M. Teillet, David G. Goodenough

LARS Symposia

A software package for the transformation of atmospheric and illumination conditions (TASIC) has been implemented on the Canada Centre for Remote Sensing's Image Analysis System. This package offers three different transformations: (1) transformation to reflectance units; (2) transformation of illumination conditions; and (3) transformation to radiance units under standard atmospheric and illumination conditions.

Atmospheric parameters can be derived from four different sources. allowing users considerable flexibility. In particular, the method of obtaining atmospheric information from the LANDSAT signals from clear water bodies (Ahern et al. 1977 a, b) has been incorporated as one of the options. It offers high accuracy …

Analyzing Accuracy Attributes Of Landsat And Digital Terrain Tape Data In The Context Of A Digital Geobase Information System, Douglas A. Stow, John E. Estes

LARS Symposia

The major conclusions reached in this research effort are: 1) Landsat derived land cover classification data are, at present, a marginally accurate data source for county-level resource management requirements; and 2) the accuracy of standard product National Cartographic Information Center (NCIC) Digital Terrain Tape data appear to be questionable, again with respect to the information requirements of county level resource managers.

Data representation accuracy has been analyzed for Landsat/MSS land cover and NCIC Digital Terrain Tape data. Lands at derived data correctly represented land cover in 71.5% of 200 randomly sampled grid cells verified against low-altitude photography. Only 61% of …

An Overview Of The Landsat-D Project With Emphasis On The Flight Segment, Vincent V. Salomonson, A. B. Park

LARS Symposia

In the third quarter of 1981, a new, experimental Earth-resources monitoring system, Landsat-D, is scheduled for launch. The characteristics of this system have been under consideration since about 1970 through a series of study efforts and with the guidance of several advisory groups composed of representatives of federal, state, and local agencies, private industry, and university personnel. From these studies and efforts evolved an Earth resources monitoring system, Landsat-D, that includes several technological advances over the capabilities provided by Landsats 1, 2, and 3. In essence, the Landsat-D system is designed to be a complete, highly automated data gathering and …

Landsat-D Data Acquisition And Processing, Pierce L. Smith, William C. Webb

LARS Symposia

A series of evolutionary changes have taken place since the early beginnings of the Landsat (Earth Resources Technology Satellite) program. Since the first satellite launch on July 23, 1972, many tens of thousands of multispectral views of the Earth have been taken and processed at the NASA/Goddard Space Flight Center (GSFC) data processing facility located at Greenbelt, Maryland. This satellite and the subsequent Landsats 2 and 3 have supplied a continuous flow of data to a widely diverse number of users for the past 6.5 years.

For the first 6 years of operation, all multispectral images were processed as photographic …

Landsat Mss Coordinate Transformations, Berthold K. P. Horn, Robert J. Woodham

LARS Symposia

A number of image analysis tasks require the registration of a surface model with an image. In-the case of satellite images, the surface model may be a map or digital terrain model in the form of surface elevations on a grid of points. We develop here an affine transformation between coordinates of Multi-Spectral Scanner (MSS) images produced by the Landsat satellites, and coordinates of a system lying in a plane tangent to the earth's surface near the sub-satellite (Nadir) point.

A Non-Interactive Approach To Land Use Determination, Ralph V. Algazi, Gary E. Ford, Doreen I. Meyer

LARS Symposia

In this paper, we report on an operational procedure for use by the Corps of Engineers to acquire land use information for hydrologic planning purposes. The operational constraints preclude the use of dedicated, interactive image processing facilities. The procedure, which is summarized in detail, combines manual interpretation techniques and the batch-mode computer analysis of Landsat digital data. An example of the application of the procedure to an urban watershed is described.

Future Trends In Image Processing Software And Hardware, William B. Green

LARS Symposia

The image processing applications in which JPL's Image Processing Laboratory is active range from planetary exploration and earth applications to biomedical applications, astronomy, and scene analysis for the robotic vehicles of the future. There are several common trends that are apparent that are common to each of these applications areas, and these trends are discussed in this paper. The trends include requirements for improved adaptive search and interrogation of large image data bases, increasing utilization of graphics data in conjunction with imagery, improved techniques for display of multispectral imagery recorded in a large number of spectral channels, methods for merging …
