Bilateral Graph
Bivariate Chloropleth Map
Given a set of geographic features, it maps two variables on a single map by combining two different sets of graphic symbols. the term "bivariate maps" specifically refers to bivariate choropleth maps that display two variables using graduated color symbols. Here we see a bivariate map showing population stats from France. http://images.google.com/imgres?imgurl=http://go.owu.edu/~jbkrygie/krygier_html/geog_353/geog_353_lo/geog_353_lo08_gr/choro_1836.jpg&imgrefurl=http://mavance2000.blogspot.com/2008/07/bivariate-choropleth-map.html&h=472&w=360&sz=79&hl=en&start=11&tbnid=6TEgPKlY89GShM:&tbnh=129&tbnw=98&prev=/images%3Fq%3DUnclassed%2Bchoropleth%2Bmaps%26gbv%3D2%26ndsp%3D21%26hl%3Den%26sa%3DN

Scatter Plots
Scatter plots usually consist of a large body of data. The closer the data points come when plotted to making a straight line, the higher the correlation between the two variables, or the stronger the relationship.

DEM
DEM (Digital Elevation Model)A digital map of the elevation of an area on the earth. The data are either collected by a private party or purchased from an organization such as the U.S. Geological Survey (USGS) that has already undertaken the exploration of the area. Digital elevation models are gray scale images wherein the pixel values are actually elevation numbers.

ISOHYETS-Rainfall
ISOTACHS
ISOBARS-Wheather
LIDAR-Manhattan
Doplar Radar-Tallahassee
A radar system used to measure the relative velocity of the system and the radar target. The operation of these systems is based on the fact that the Dopplar frequency shift in the target echo is proportional to the radial component of target velocity. Most often used to show moving weatherpattern. Shown here is a map showing Tallahassee and the rain about to be dropped on our heads.
Infrared Aerial Photos
Infrared film and infrared digital sensors are sensitive to a certain portion of the spectrum of light, and by careful filtration, processing and selection of films, infrared aerials can provide invaluable information. Usually infrared is sensitive to heet. Shown here is a map of Florida which shows a darkened area of hot fires and a lightened area of chilled cloud tops.

Week 7 Post-Map of Active Fires in the US as of June 24th
This is supposed to be a Remote sensing map of active fires in the US as of 24 June 2008. I pulled the image from the US Forestry Department's website that used the KML file to show active fires. In Google Earth the image was much bigger and showed the concentration of fires in Northern California. Im not sure why the image is so small on this or why it doesn't show the active fires as it does when the image is shown in Google Earth.
