This weeks assignment was to create a dot map representing the population distribution in South Florida. To accomplish this, we were required to create a map in which eat dot represented a specified number of persons and to have that dot be placed at a reasonable location (i.e. one that suggests population density).
A dot map is used to display spatial phenomena in such a way that the end user can confidently determine areas of high and low density occurrence. In the map above, it is obvious that Miami and Tampa have high population density and that central Florida has low density. The key to placing the dots is the existence of a layer 'hidden' in the final map; this layer was a polygon of urban areas. The dots, which represented the population of the entire county, were then only placed within these urban areas to better show the true population distribution.
