A thematic map is a type of map or chart
especially designed to show a particular
theme connected with a specific
geographic area. These maps "can
portray physical, social, political,
cultural, economic, sociological,
agricultural, or any other aspects of a
city, state, region, nation, or continent".
A thematic map is a map that focuses on a specific
theme or subject area, whereas in a general map the
variety of phenomena—geological, geographical,
political—regularly appear together. The contrast
between them lies in the fact that thematic maps use
the base data, such as coastlines, boundaries and
places, only as points of reference for the phenomenon
being mapped. General maps portray the base data,
such as landforms, lines of transportation,
settlements, and political boundaries, for their own
sake.

Thematic maps emphasize spatial
variation of one or a small number of
geographic distributions. These
distributions may be physical
phenomena such as climate or human
characteristics such as
population density and health issues.
Barbara Petchenik described the
difference as "in place, about space."
While general reference maps show
where something is in space, thematic
maps tell a story about that place.
Thematic map are sometimes referred to as graphic
essays that portray spatial variations and
interrelationships of geographical distributions.
Location, of course, is important to provide a reference
base of where selected phenomena are occurring.

WHAT IS A THEMATIC MAP?
There are three classes of maps:
1) general reference maps which show the locations of a variety of features.
2) thematic maps which show the distribution of a single attribute (characteristic)
or the relationship between several attributes.
3) charts which are used primarily for navigational purposes.
Thematic maps can cover a variety of characteristics from soil types to population
density. It is the cartographers responsibility to make sure that the map shows the
correct distribution or the relationship between the various attributes
WHEN DO WE USE THEMATIC MAPS?
•Thematic maps can show not only the distribution of a single attribute, such as
the result of a presidential election by state, but they can also show the
relationship between several different attributes. For instance, a thematic map
could show the results of that same presidential election with the number of votes
divided according to the gender or age group of the voters.
•Some maps that deal with a single attribute such as population, may not
necessarily be thematic maps. If the map shows the actual location where the
people live, it would be a general reference map. A map showing the distribution of
that same population would be a thematic map.

HOW DO WE SCALE A THEMATIC MAP?
Until fairly recently, thematic maps were usually made with a small scale, because
the data was rather coarse, and it was more important to show the basic
distribution pattern than the map location for the data. In recent years, however,
better data has become available and thematic maps are being made with a larger
scale to show more accurate spatial information.
WHAT MAKES A GOOD THEMATIC MAP?
When designing a thematic map, a cartographer must be careful to portray the
data on the map so that it will be easy for the audience to use and understand. This
is accomplished mainly with the marks and symbols that the cartographer uses to
represent the data. The designer should also give an adequate locational base for
the map.

McDonalds use prefabricated
structures for their buildings, and set
a record of constructing a building
and opening for business within 13
hours.
CONCLUSION
Because of the design simplifications modern
architecture provides many in the manufactured
housing sector generally feel that modern
architecture designs are better suited for prefab home
construction.
