Thematic map is a very general term used to describe a map that deals with the subject of a specific theme- that is, it portrays data, visually, for a specific region, that has to do with the whatever theme the cartographer wishes to portray. The themes are endless, ranging from social, to cultural, to political, to economical, etc. This particular thematic map portrays the basic resources and processing for the country of Belgium in the year of 1968. The resource shown in blue is coal, and the processing of iron and steel share a symbol, nonferrous metals share a triangular symbol, and petroleum has its own intricate symbol. This map is great for showing an overly simplified view of where the major resources or processing may take place in the country, and reminds me of the old empirical Roman military maps, both in simplicity as well as pictogram representation of the elements.
