The red dots on this GIS generated map are outlines of cities seen from above. The strength of this map is its degree of precision in displaying the population grouping it actually sees. It is very possible, however, that The Dot density Map below offers a different approach to portraying the varying arrangements and densities of the  population. The way this map works it that a region is given a specified number of dots for the size of the population per square mile. The more people per sqaure mile, the more dots are applied to the region. This  type of map which employs one color is good for making a strong impression at first glance. However, it is easy to make flaws in this type of hand drawn map because all dots need to be the same size and in bulbous regions, it would be very hard to distinguish random less populated because it is hard to distinguish individual dots when they are all so class together and appear to be one block . There are many more ways in which a population map could be organized. For example, ifferent color shadings could be applied to different degrees of density.
