AERIAL MEASUREMENT ERROR WITH A DOT PLANIMETER: SOME EXPERIMENTAL ESTIMATES-FINAL REPT

THE PRESENT STUDY ANALYZES MORE COMPLEX SHAPES THAN PREVIOUSLY STUDIED, AND UTILIZES A COMPUTER TO SIMULATE A MULTIPLICITY OF DOT GRIDS MATHEMATICALLY. RESULTS INDICATE THAT THE NUMBER OF DOTS PLACED OVER AN AREA TO BE MEASURED PROVIDES VIRTUALLY THE ENTIRE CORRELATION WITH ACCURACY OF MEASUREMENT, THE INDICES OF SHAPE BEING OF LITTLE SIGNIFICANCE. EQUATIONS AND GRAPHS ARE PROVIDED FROM WHICH THE AVERAGE EXPECTED ERROR, AND THE MAXIMUM RANGE OF ERROR, FOR VARIOUS NUMBER OF DOT POINTS CAN BE READ. /AUTHOR/
