Abstract
At the usual methods, geological data of borehole are generally collected and recorded from core samples and operational tests by geologist in situ. At this time, charecters of lithology and stracture are coded by observers following by the code book, so the quite lots of information are likely to be out of the data sets.
Then, we have developed the ststem by which the image data collected from boring hole are recorded, degitized, reconstructed, analized and displayed.
