Abstract
Engineering geological map is generally regarded as a practical expression of a three dimensional geological model which is made from the various geological information for construction works. Users of the geological map reconstruct an another model on the basis of the given information on the map. Finally, the geological information is converted into engineering forms for designing.
Considering this utility environment of the engineering geological map, it must have a function as a information medium about geological information from geologists to designers. To enable designers to obtain reasonable engineering information from the model, it is required that above-mentioned two models coincide with each other.
Practical methods to get the coincidence of the models are as follows; (i) establishment and standardization of mapping algorithm, (ii) expression of The rightfulness or fuzzyness of the information, (iii) standardization of expression forms of the information on the engineering geological map.
