The computer graphical method for analysis of remote sensing multi-spectral image data is proposed. Three-dimensional histogram is constructed in three-dimensional feature space from the image data and represented by three-dimensional computer graphics. On the histogram fine structure of distribution of data in the feature space can be observed. Therefore the categories of remote sensing multi-spectral image data can be identified easily on the computer screen. Each distribution of water, vegetation and soil etc. has its charasteristic features in the histogram. One of the most distinguished features is that distribution of data of each category is long and narrow, and the principle component axes of the categories concentrate on a point near the origin of the feature space.
