—An Applied Case of Radar Imagery to the Yakushima Island, Japan—Yasushi YAMAGUCHI, Hirokazu HASE1983 Volume 22 Issue 3 Pages 4-13

JOURNAL FREE ACCESSThe result of lineament analysis of the Yakushima Island, Southwest Japan, using Landsat, radar (SAR) and aerial photograph imagery was compared to study the difference caused by various image data. It differs owing to variation of resolution (R) and scale (S) of each imagery and indicates that lineament analysis can be performed most efficiently in case of R×S = 0.01 (cm) .
The magnitude-frequency relation for length of fractures was examined by combining the results of lineament analysis of these various kinds of imagery. It is experimentally represented as
log N=k-m log L
where N is the number of lineaments whose length is ranging from L to L±1/2·ΔL and k, m are constants. The m value gives decreasing ratio with respect to the length of lineaments and is calculated as 2.30, which seems reasonable value for representing the magnitude-frequency relation of fractures compared with several reports thus far made.View full abstractDownload PDF (1089K) -
Ryutaro TATEISHI1983 Volume 22 Issue 3 Pages 14-25

Released on J-STAGE: March 19, 2010
JOURNAL FREE ACCESSMany three dimensional representation outputs can be seen at the present time according to the progress of computer.
This study has developed an algorithm to produce a projective transformed image for three dimensional representation. By this algorithm, a large number of data as much as about 2000 by 2000 which is given on a terrain, point by point, can be represented three dimensionally by a projective transformed image which consists of about 2000 by 2000 pixels.
This paper, first, describes usual methods of three dimensional representation and, secondly, explains the developed algorithm and finally displays the output images by developed algorithm.View full abstractDownload PDF (4412K) -
