Multispectral Data Compression Through Transform Coding And Block Quantization, P. J. Ready, P. A. Wintz

LARS Technical Reports

Transform coding and block quantization techniques are applied to multispectral data for data compression purposes. Two types of multispectral data are considered, (1) aircraft scanner data, and (2) digitized satellite imagery. The multispectral source is defined and an appropriate mathematical model proposed.

Two error criteria are used to evaluate the performance of the transform encoder. The first is the mean square error between the original and reconstructed data sets. The second is the performance of a computer implemented classification algorithm over the reconstructed data set. The total mean square error for the multispectral vector source is shown to be the …

Mapping Of Soils And Geologic Features With Data From Satellite-Borne Multispectral Scanners, M. F. Baumgardner, S. J. Kristof, W. N. Melhorn

LARS Technical Reports

The ERTS-1 satellite provides opportunity for quick inventory and assessment of geologic, soils, and vegetative cover aspects of large-scale areas of the Earth's surface. Collin County, Texas, U.S.A., a 2270 Km² area of relatively simple geology and soil associations was chosen for initial study, using ERTS-1 4-channel multispectral scanner data. These data were analyzed by computer-implemented pattern recognition techniques developed at the Purdue University Laboratory for Applications of Remote Sensing (LARS). The results indicate excellent visual correlation, on a gross scale, between automatically produced maps and existing geologic and soils maps and field information.

Determining Density Of Maize Canopy: Ii. Airborne Multispectral Scanner Data, E. R. Stoner, M. F. Baumgardner, J. E. Cipra

LARS Technical Reports

Multispectral scanner data were collected in two flights over a light colored soil background cover plot at an altitude of 305 m. Energy in eleven reflective wavelength bands from 0.45 to 2.6 µm was recorded by the scanner. Four growth stages of maize (Zea mays L.) were present at the time of each over flight, giving a wide range of canopy densities for each flight date. Leaf area index measurements were taken from twelve subplots at the time of each overflight, and were used as a measure of canopy density.

Ratio techniques were used to relate uncalibrated scanner response to …

Measurements Program In Remote Sensing, Leroy F. Silva

LARS Technical Reports

The measurements program at LARS/Purdue has been concerned with five basic research areas during 1971. These areas are (1) the influence of haze layers upon remotely sensed surface properties, (2) electrical methods of soil moisture measurement, (3) thermographic studies of vegetation under nutritional stress, (4) improved field spectroradiometry, and (5) biological spectrophotometry.

All of the projects have risen out of problems generated from the overall laboratory mission. the emphasis in the paper is on instrumentation and techniques; whereas, related data and results on specific projects will be reported elsewhere. Each of the subject areas will be discussed individually.

Influence Of Haze Layers Upon Remotely-Sensed Surface Properties, G. M. Jurica, W. L. Murray

LARS Technical Reports

During the summer of 1971 the Laboratory for Applications of Remote Sensing (LARS) participated in an experiment to detect disease in corn caused by southern corn leaf blight. An aircraft was used to measure in several spectral intervals between 0.46 and 2.60 micrometers the solar radiation reflected by the earth's surface. The analysis of data gathered during the 1971 Corn Blight Watch Experiment revealed a number of unexpected features. One of particular interest was the appearance of bright and dark sides along the flightline of the aircraft.
