But the main advantage of multispectral survey
is the fact that black-and-white spectral images
allow to make precise photometric measurements of
the ground objects which are the basis for a
development of quantitative , visual —instrumental and
hardware interpretat ion methods. We think that in
the future these particular directions of
mu1tispectra1 space photosurvey data application will
play the most important roles.
The experience of application of multispectral
□hotodata confirmed the significant increase of the
problems which can be solved by remote sensing data
and a raise of the efficiency of these data
application for natural resources study and
ecological investigations.
Mu1tispectra1 photocamera MKF—6 (MKF—6M, MKF—6MA),
developed by "Carl Zeiss Jena” company from German
Democratic Republic and installed on manned orbital
station,allowed not only to elaborate the methods and
facilities for multispectral photodata processing, and to
solve a set of many scientific and production tasks but to
move long ahead in raising the efficiency of multispectral
survey, as the results of its use allowed to substantiate
technical specifications of MK-4 camera.
The present report presents main specifications
of new Soviet multispectral photocamera MK—4 and
compares it to the MKF—6 camera. The samples of MK—4
photoimages are shown.
MK—4 camera is installed on unmanned space vehicle of
"RESOURCE—F“ type and allow for a survey at the scale of 1:
660 000 to 1:1 500 000 in dependence of the selected orbit
altitude with angle of its declination to the equator plane
of 82 deg.
MK-4 system consists of multispectral
photocamera CA—M with four objectives and of star
monochannel photocamera CA—3P designed for
determination of elements of exterior orientation of
the ground surface images.
