IN THE CLASSIFICATION PROCESS OF URBAN LATTICE DATA, A KIND OF CONTRADICTORY CLASSIFICATION ARISES, WHEN TWO OR MORE RELATIONAL ITEMS ARE INDEPENDENTLY CORDED TO GRID CELLS. FOR INSTANCE, IN CASE OF LAND USE ZONING AND BULK ZONING, THE BOUNDARY CELLS ADJACENT TO MORE THAN THREE DIFFERENT ZONES HAVE POSSIBILITY TO BE CLASSIFIED WITH THE NONEXISTENT COMBINATION OF THE ZONE CATEGORIES. FOR THE REGIONS IN WHICH THE RATIO OF CONTRADICTORY CELLS IS COMPARATIVELY LARGE THIS PROBLEM CAN BE QUITE SIGNIFICANT. THIS PAPER ATTEMPTS TO DEVELOP A MODEL FOR ESTIMATING THE NUMBER OF THE CONTRADICTORY CELLS.
