THE EFFECT OF SHADED RELIEF TERRAIN REPRESENTATION ON MAP INFORMATION ACCESSIBILITY

TWO EXPERIMENTS WERE CONDUCTED TO MEASURE THE EFFECT OF SHADED RELIEF TERRAIN SYMBOLOGY ON HUMAN MAP READING PERFORMANCE. THE SPECIFIC HYPOTHESIS BEING TESTED IN BOTH EXPERIMENTS WAS AS FOLLOWS: THAT THE USE OF THE SHADED RELIEF TECHNIQUE OF TERRAIN REPRESENTATION DECREASES THE LEGIBILITY OF ALL OTHER SYMBOLS APPEARING ON THE MAP THEREBY MAKING THE INFORMATION REPRESENTED BY THOSE SYMBOLS LESS ACCESSIBLE TO THE MAP READER. THIS RESULTS IN A SIGNIFICANT INCREASE IN THE TIME NECESSARY TO EXTRACT REQUIRED ELEMENTS OF NON-TERRAIN INFORMATION FROM THE MAP. RESULTS OF THE INITIAL EXPERIMENT CONFIRMED THIS HYPOTHESIS. A REPLICATION EXPERIMENT FOUND A STATISTICALLY INSIGNIFICANT DIFFERENCE BETWEEN THE TWO VERSIONS OF THE TEST MAP. /AUTHOR/
