摘要:

The application of methodology developed for peat resource survey has illustrated the usefulness of multi-level and multi-band aerial photography in classifying Landsat multispectral imagery. Ground truthing to characterize the thematic maps plotted from the aerial photography and Landsat imagery was based primarily on vegetation surveys. The results of this work are illustrated with a series of maps and photographs and the usefulness of the approach is assessed.

摘要:

An expedient and accurate method for assessing the effect of intensive agriculture on a watershed water balance is needed, particularly for those areas where well irrigation is prevalent or becoming more so. Digital image processing of Landsat-3 data discriminated major field crops and forests in Tift County, Georgia, necessary for a water use assessment. A water balance model based on a modified Penman relationship was developed to estimate evapotranspiration. The remotely sensed data and local meteorological data were then used in a hydrologic model to predict watershed daily water balance. The simulation was evaluated by comparing model performance with water balance measurements for a 15.5 km2instrumented agricultural watershed.

摘要:

This paper presents an argument that remote sensing image processing should attempt to copy human abilities. The techniques of spectral analysis and texture analysis are reviewed and compared in their abilities to emulate human interpretation. A preference for texture analysis is expressed.

摘要:

A new era of remote sensing for coastal and oceanographic monitoring was born on 26 June 1978 with the launch of Seasat. Duck-X was a 2 month experiment conducted during August to October 1978 off the east coast of the U.S.A. for the validation of the Seasat synthetic aperture radar (SAR), During this field experiment, various oceanographic phenomena were monitored. Ground truth observations of these phenomena have been correlated with Seasat SAR imagery. The ground truth sensors included airborne photographic and radar imagery, meteorological satellite imagery, land based radars, and conventional wave gauges. This paper focuses on ocean surface waves, ocean currents and coastal inlet discharge
