A PILOT PROJECT ON THE STORAGE AND RETRIEVAL BY COMPUTER OF GEOLOGICAL INFORMATION FROM CORED BOREHOLES IN CENTRAL SCOTLAND

THIS REPORT DESCRIBES A METHOD FOR FILING AND RETRIEVING RELEVANT DATA FROM THE LOGS OF CORED BOREHOLES WITHOUT LOSS OF IMPORTANT GEOLOGICAL INFORMATION. A SCHEME, KNOWN AS THE DETAILED SCHEME, HAS BEEN DEVELOPED WHICH ENABLES THE GEOLOGIST TO PRESENT HIS RECORDS FOR COMPUTER DATA PREPARATION IN A FORM SIMILAR TO THAT IN WHICH HE HAS ALWAYS LOGGED BOREHOLES IN THE FIELD. A VOCABULARY OF SOME TWO HUNDRED WORDS HAS BEEN FOUND ADEQUATE TO DESCRIBE THE DATA FROM CORED BOREHOLES USED IN THIS INITIAL PROJECT, WHICH COVERS ALL CUT CARBONIFEROUS STRATA IN THE MIDLAND VALLEY OF SCOTLAND. A SELECTION OF WORDS FROM THE VOCABULARY IS USED BY THE GEOLOGIST IN THE FIELD TO DESCRIBE EACH ITEM AND THESE DESCRIPTIONS CAN BE PRESENTED DIRECTLY TO THE COMPUTER WITHOUT PRIOR CODING. DATA ARE CODED BY THE PROGRAM FOR STORAGE, IN CONDENSED FORM, ON MAGNETIC TAPE. FIELD TRIALS HAVE SHOWN THAT GEOLOGISTS HAVE NO DIFFICULTY IN USING SUCH A SCHEME. ANOTHER SCHEME, KNOWN AS THE OUTLINE SCHEME, HAS BEEN DEVISED TO INCLUDE A SUMMARY OF THE MOST IMPORTANT NON-LITHOLOGICAL INFORMATION FROM A BOREHOLE. DATA FOR THIS WILL NORMALLY BE PREPARED IN THE OFFICE AND ARE PRESENTED TO THE COMPUTER IN CODED FORM, IN FIXED FORMAT. THE DETAILED AND OUTLINE FILES CONSTITUTE THE MOST COMPLETE DATA BANK WHICH IS AVAILABLE TO THE RETRIEVAL PROGRAM. A RETRIEVAL LANGUAGE SIMILAR TO NORMAL ENGLISH HAS BEEN DEVELOPED WHICH ENABLES THE GEOLOGIST TO PUT QUESTIONS TO THE COMPUTER IN A WAY WHICH IS REASONABLY EASY TO UNDERSTAND. PRESENT OUTPUT IS IN THE FORM OF LISTINGS BUT IT IS HOPED IN THE NEAR FUTURE TO PROVIDE APPROPRIATE OUTPUT IN OTHER FORMS, INCLUDING CONTOUR MAPS. /AUTHOR/
