JOURNAL FREE ACCESSIn order to assess the coastal environment and to monitor water pollution from the air, it is necessary to clarify the relationship between spectral response of natural water and the water's quality. For a two year period from 1975 to 1977, studies of observation of transparency and spectral reflectivity from the water's surface were carried out on several lakes in Japan and in the sea around Japan by the authors.
Water samples were also taken during this time. The sampled water was analyzed quantitatively regarding items of optical water quality such as suspended solids and chlorophyll concentrations.
In this paper, the relationship between spectral responses from the water's surface and the water's quality, which were deduced through our observations, are discussed. As the polluted water had a higher spectral response than clear water, it was concluded that observation of spectra of backscat-tered light from the water's surface is a useful indicator of water quality.View full abstractDownload PDF (681K) -

JOURNAL FREE ACCESSThis paper describes a special character of the multispectral scanner mechanism and can be related to such parameters as sun direction, relative height and scan angle between the dead and shadow angle space by the MSS.
This correlation can be easily observed by figure 2-10, 12. Next, it describes a approximate rectifiable theory of the MSS imagery that is based on Konecny's theory. Using this theory, behaviors of the rectifiable elements are investigated; φ, ω, κ, bx, by, bz.
The result is applied to determine the overlap quantity by the flight plan and will be suggest to use hardware of a regenerated MSS imagery in the futuer.View full abstractDownload PDF (1342K) -

JOURNAL FREE ACCESSThe LANDSAT 1 and 2 which were launched in July, 1972, and January, 1975, respectively, have made a great contribution for demonstrating the fact that the Earth exploration satellites are very useful in various fields such as the development of the Earth resources, the effective use of lands the monitoring of the atmosphere, and so on.
In Japan, the survey on the use of the Earth observation satellites has been initiated in 1970, and the development of Japanese Earth observation satellite system was planned in 1976. In parallel with this development, the construction of the LANDSAT receiving station was also planned with a taget of its operation in 1979.
This paper describes, in the beginning, the principal characteristics of the LANDSATs (1, 2, C and D) and image signals transmitted from these satellites, and then presents the constitution and the characteristics of the Japanese ground system under construction. Finally, the problems associated with the system are mentioned about the radio interference to and from the terrestrial Communications system, etc.View full abstractDownload PDF (910K) -
