    Lineament analysis, made through the observation of remote sensing data, is encountered various bias effects. In this paper, the bias effects are analyzed firstly by grouping the process of lineament extraction into three stages, that is; ground based effects (A-factor), image based effects (B-factor), and human effects (C-factor) . These effects change the size distribution of lineaments. The distribution of the extracted lineaments can be formulated in the following equation.
    n4(L)≅c'×L- (D+1) ×∫Llmin1/√2πσl×exp[-(log l-μ)2/2σ2]dl
    where n4 (L) is the frequency of extracted lineaments with lengthL.lis the recognizable length of a lineament whose actual length isL. Dis the fractal dimension.c', σand μ are constants.

    Recently, spatial resolution of sensors on board satellites are becoming higher and higher, but high resolution sensors are generally narrow in observation covering and rather long in repeatability. For that reason, low resolution sensors are under reconsideration for the actual use, because they can cover a wide area instantly.
    The problem in using the low resolution sensors is difficulty selecting the GCP for geometrical correction. The conventional method relies upon direct selection by interpretation of human eyes. But it is not accurate because the topographic characteristics are not always clear. This paper describes the method of extracting high accuracy GCP for high accuracy geometrical correction, even on low resolution images.

  • Eruption, Crack, and Gave-in of Mihara Volcano, Izu-Ooshima Is.

    Mihara Volcano, lzu-Ooshima Is., erupted violently on 15th November, 1986. At that time, vast erupted lava covered in craters on summit of the Volcano. After one year, the same volcano erupted again on 16th November, 1987. And then, though this eruption was on a small scale, the craters caved-in.
    Measurement on distribution of natural environmental gamma ray over lzu-Ooshima ls. was carried out on 4th December in 1986 and on 19th January in 1987, by the airborne gamma ray spectrometer system of AERRS on a helicopter Bell 212. Moreover, thermal imageries on the same island by the airborne thermal infrared video camera of AERMS were recorded at the following three epochs: on 28th November in 1986 after the first eruption, on 12th November in 1987 before the second eruption and on 19 th November in 1987 after the second eruption.
    As a result, some new facts on volcanic eruption and cave-in of the crater were obtained, that is,
    1) On the occasion of volcanic eruption, spectrum composition of natural environmental gamma ray over the volcano shows some significant changes.
    2) Previous to cave-in of the crater, a ringlike thermal anomalous zone appears on the outskirts of crater, and it corresponds to a boundaryline of depressed area.
