Figure 1 shows the thematic map
of spatial distribution of horseweed plants (Figure 1A) and the polygon representing its occupation area (Figure 1B).
By overlapping the information from all the thematic map
final scores are allocated, as shown in Figure lb.

Then classification of these values is carried out in to two classes and thematic map
With these studies in mind, a clear gap exists in the literature concerning the interpretation and testing of thematic map

The visualization can be either a thematic map

For example, a Texas state road map would be an example of a reference map, but a map showing each county of Texas with color representing its population would be an example of a thematic map
Determine whether there is congruency between the actual and predicted illness rates for countries near and distant from the equator, and discuss how a thematic map
Because the size of each geographic area varies, absolute statistics are at best suspect and at worst misleading when presented on a thematic map
