A correlation matrix describes correlation among sets of variables. It is always symmetric because the correlation between Xi and Xj are the same as the correlation between Xj and Xi http://yin.che.wisc.edu/images.htm

Similarity Matrix

A similarity matrix is a matrix made of scores that show similarity between two data points. http://tomcat.esat.kuleuven.be/txtgate/tutorial.jsp

Isopleths

Isopleths are lines that connect units of equal distance. On maps they can be used for mapping elevation, precipitation or any other of a number of measurements.

Isotachs



Isotach maps show wind speed. By definition an isotach is a line connecting points of equal wind speed

Isopach

Isopach maps display thickness. These contours connect points of equal thickness. This is commonly thickness of a rock unit, being the stratigraphic thickness as opposed to vertical thickness

Isoyhet


Isoyehts show precipitation amounts. An isohyet is a line connecting points of equal precipitation amounts.

Statistical Map

A statistical map givea a statistic of the time course over a a specificed set of time periods. This can measure things such as rainfall, population or who is on the internet, as in my example.

Cartogram

A cartogram is a map where the variable being shown is substituted for land area. This distorts the geometry of the map.

Isolines

An isoline of a function of two variables is a curve along which the function has a constant value. This is also known as a contour map, where the contour is the interval is the distance between contour lines.

Choropleth Map


A choropleth map is a type of thematic map. It uses shades or patterns in proportion to the measurement of a statistic. It provides an easy way to visualize how a measurement varies across a geographic region.

Propaganda Maps

A propaganda map is often used by government officials to try to sway the way people think. They will take something that is real, and configure it in such a way that it will cause an individual to think differently about something that is going on in the world around us. The one I have chosen is based on what was taking place during the 80's and how President Reagan may have saw the world around him.

Hypsometric


Hypsometric maps are also called relief maps. What they do is show the elevation of a an area of land. They do this by using a succession of colors. The colors vary based on certain intervals of land elevation. They usually use the rule of "higher is brighter" meaning that the darker the color the higher the terrain.

PLSS Map


PLSS is Public Land Survey Systems. This is used to survey and identify land parcels, usually for deeds tor rural or wild areas. It is often known as the rectangular survey system, although non rectangular methods can be used.

Cadastral Map


A cadastral map shows boundary and ownership of specific parcels of land. It has been said that the cadastral map makes a place tangible to the outsider. It also allows states and towns to collect data on their subjects. It often includes street names and lot numbers. The map I have chosen is a portion of Washington DC

Thematic Map


A thematic map is specially designed to specifically address a certain theme within a geographic area. This can be physical, social, political, cultural, economical or any other aspect of a given region.

http://www.mapsunlimited.com/sample/BBBNAmap.html

Planimetric Map


A planimetric map shows only the horizontal positions of things on the earths surface. This is in contrast to the topographic which gives horizontal and vertical. These maps will show buildings, highways, reservoirs, docks, piers, bridges and other pieces of construction or features. The map I have chosen is of a hospital.

http://www.spatialdc.com/projects/hospitals.htm

Topographic Map


A topographic map uses large scale images and detail. It will usually give representation of relief using contour lines,but this can be done in a variety of ways. Topographic maps usually include both natural and man made features.

Mental Maps


A mental map is a map perceived in a person's mind. Proportions and distances are often not correct when it is actually drawn out. This is often seen in maps for amusement parks. It gives you a vague idea of where things are, but distances between things, and size or rides in relation to other places in the park are different.
