Forest Stand Delineation From Unsupervised Classification Of Optimal Landsat Spectral, Landsat Texture And Topographic Channels, Thomas L. Logan, Alan H. Strahler
Forest Stand Delineation From Unsupervised Classification Of Optimal Landsat Spectral, Landsat Texture And Topographic Channels, Thomas L. Logan, Alan H. Strahler
LARS Symposia
Landsat data, in conjunction with collateral data sources such as synthesized texture channels and digital terrain models, can be used to delineate forest stands and other ecological land units found in the coniferous North American forest environment. Incorporation of texture and terrain channels enhances site-specific stratification of Landsat data, promoting delineation of forest stand units of a size and homogeneity approaching those found on manually prepared maps used in the management of timber, range, wildlife, watershed and recreational resources.
The procedure is a joint research effort between the Jet Propulsion Laboratory of the California Institute of Technology and the University …

Field Research On The Spectral Properties Of Crops And Soils, M. E. Bauer, L. L. Biehl, B. F. Robinson
Field Research On The Spectral Properties Of Crops And Soils, M. E. Bauer, L. L. Biehl, B. F. Robinson
LARS Technical Reports
This report describes the experiment design, data acquisition and preprocessing, data base management, analysis results and development of instrumentation for the AgRISTARS Supporting Research Project, Field Research task. It reports results of several investigations on the spectral reflectance of corn and soybean canopies as influenced by cultural practices, development stage and nitrogen nutrition. Results of analyses of the spectral properties of crop canopies as a function of canopy geometry, row orientation, sensor view angle and solar illumination angle are presented. The objectives, experiment designs and data acquired in 1980 for field research experiments are described. The development and performance characteristics …

An Assessment Of Landsat Data Acquisition History On Identification And Area Estimation Of Corn And Soybeans, Marilyn M. Hixson, Marvin E. Bauer, Donna K. Scholz
LARS Technical Reports
During the past decade, numerous studies have demonstrated the potential of satellite remote sensing for providing accurate and timely crop area information. This study assessed the impact of Landsat data acquisition history on classification and area estimation accuracy of corn and soybeans.
Multitemporally registered Landsat MSS data from four acquisitions during the 1978 growing season were used in classification of eight sample segments in the U.S. Corn Belt. The results illustrate the importance of selecting Landsat acquisitions based on spectral differences in crops at certain growth stages.
A Soil Moisture Reflectance Model In Visible And Near Ir Bands, John K. Park
A Soil Moisture Reflectance Model In Visible And Near Ir Bands, John K. Park
LARS Symposia
Reflectance variation of bare soil with different moisture contents was described by a one-dimensional model of soil-water mixture employing the two-stream approximation of the radiative transfer equation. The concept of bulk absorption and scattering coefficients of electromagnetic radiation in the surface layers of moist soil was introduced for derivation of the Kubelka-Munk equations, which had been applied to various reflectance problems. The diffuse reflectivity of moist soil in visible and near-infrared bands could be explicitly expressed in terms of a moisture variable as well as optical characteristics parameters, or vice versa. A method was developed to determine these characteristic parameters …
