Abstract
A map is the major tool in measuring fractal dimension of a river line whereas in this paper satellite remote sensing data were used in conjunction with the box-counting method. Satellite numeral data were of LANDSAT /MSS, LANDSAT/TM and SPOT/HRV. Some rivers in the northern part of Kyusyu district, Japan were treated with, fractal dimensions of which were measured by using not only each satellite numeral data but a combination of two or three kinds of satellite numeral data. Furthermore a change of Shoka river in China for floods were measured by fractal theory. The following conclusions were obtained: (1) Fractal dimensions of objected rivers had valuesclose to 1.0 showing that the river lines were not so complex. (2) There was little difference in fractal dimension between by use of each satellite numeral data and a combination of two or three kinds of satellite numeral data. (3) Satellite numeral data were clarified to be very useful in measurement of fractal dimension of river lines. (4) A spread of a river width by floods were measured by fractal dimension using satellite numeral data.
