classed choropleth map

http://personal.uncc.edu/lagaro/cwg/color/Choropleth-5Good.gif

This map uses smaller intervals to portray the data. There is a scale and is usually broken into color differnces to match the area on the scale.

Bivariate Choropleth Map

http://www.pop.psu.edu/images/gia/maps/changeanim.gif

A bivariate map displays two variables on a single map by combining two different sets of graphic colors. This shows two different information at the same time. This isa gif animation that shows the two.

Univariate Choropleth Map

dISPLAYS ONLY SINGLE VARIABLE. THIS IS SHOWING THE POVERTY IN THE US.

standardized choropleth maps

Allow comparison of distribution among different areas.

Unstandarizied Choropleth

This map shows hazaderous waste. Unstandarizied Choropleth maps are maps where the data has not been averaged. The data is presented in numerical values.

DLG

THese are digital line graphs that show boundaries, roads, and other various information found on topographical maps.

LIDAR

LIDAR stands for Light Detection and Ranging. This type of remote sensing employs the use of laser light to help gather images. It stands for Light Detection and Ranging. This type of remote sensing employs the use of laser light to help gather images.

Nominal Area Choropleth Maps

http://giscommons.org/files/2009/08/6.6.gif

This type of data is quantitative and random and broken into different colors . The different colors represent variations in data. Most will havea key onthe side to see where the colors fall.

Bilateral graph

By using two colors and comparing right next to each other you can really tell the difference in this graph.

Lorenz curve

This graph is used to display probility distribution. This one shows the total population compared with the total income.

index value plot

http://content.ll-0.com/pmimassbay/word_images/2925232_image003.gif?i=021307053031

This kind of plot is where a value is actually plotted and not numbered.

Popluation profile

this compares the total population with a specific date, for example, in this graph, it is what age the population is.

Triangular plot

THis shows data in different colors and by putting them all in one space it is easy to compare.

Parallel coordinate graph

This graph displays multiple data on one graph. You can distinguish them by the color.

histogram

http://www.aivosto.com/project/help/pm-histogram.gif

These show frequence on a specific topic by labeling what and how much. And then using lines and colors to distinguish.

box plot

http://math.youngzones.org/boxplot.gif

these maps show the range of the data. You can see this by the extension of the box.

stem and leaf plot

This map is used to show different numerical data.

similarity matrix

These types of maps show how similar things are. The levels of similarity are show by boxes and colors. Red-the most, Blue-the least.
