dot-distribution maps display quantitative data as a dot,representing a number of the factors found within an area. The dot distribution pattern reflects the general locations where the factor was most likely to occur. The pattern and number of dots within the area reveal the density of the phenomenon. Two types of dot-distribution maps are: first the traditional dot map showing the distribution of a phenomenon, traditional dot map symbolizes data with blue dots, second type is an increase/decrease dot map showing increasing (positive) and decreasing (negative) data values as they related to the last agricultural census.
