"DLG map"

DLG, digital line graph, is a form of a digital map created by the USGS that uses a topological vector model. This is a DLG map of Columbus, Ohio. http://daniellemapcatalog.blogspot.com/2008_11_01_archive.html

"DRG map"

DRG, digital raster graphic, is a scanned copy of a USGS topographic map. It represents all georeferenced images on earth. This map shows the Potomac River. http://egsc.usgs.gov/isb//pubs/factsheets/fs08801.html

"Isopleth map"

An isopleth map generalizes and simplifies data with a continuous distribution. This map shows isopleths of air pressure. http://albanesemapcatalog.blogspot.com/2011_04_01_archive.html

"Isopach map"

An isopach map is a map illustrating variation of thickness within a stratum. Isopachs are contour lines of equal thickness over an area. This map is showing the thickness near the Michigan area. http://shannonmapcatalog.blogspot.com/

"Isohyets map"

An isohyet is a line joining points of equal precipitation on a map. This is map shows the average rainfall in Hong Kong. http://www.hko.gov.hk/wxinfo/pastwx/mws201206.htm

"Isotachs map"

Isotach lines are equal in wind speed. The direction of the "L" looking objects indicate from what direction the wind is originating. http://candacesmaps.blogspot.com/2010/12/isotachs.html

"Isobars map"

An Isobar is a line connecting points of equal atmospheric pressure. In this map of the United States the winds flow roughly parallel to the isobars. http://www.mv.k12.wa.us/science/integrated/athena/curric/weather/hsweathr/isobar.html

"LIDAR map"

LIDAR (Light Detection And Ranging) is an optical remote sensing technology that can measure the distance to often using pulses from a laser. A LIDAR map gets its name from light, detection, and ranging. It measures the properties of the scattered light to find the range of things in the distance. This is a three dimensional model taken September 17, 2001 of the World Trade Center area in New York City. The images were used by emergency managers to assess damage through the smoke after the World Trade Center Tragedy. http://www.loc.gov/exhibits/911/911-maps.html

"Doppler radar map"

A doppler radar map uses microwaves to track direction and speed of suspended water in the atmosphere and determines the motion. This is a doppler radar of a hurricane over the east coast of Florida. http://www.noaanews.noaa.gov/stories2004/s2311.htm

"Black and White aerial photo"

A black and white aerial photo is similar to that of an infrared photo except for the fact that a black and white camera is used above an area. In this photo it is a picture of Pearl Harbor. http://pubs.usgs.gov/of/1995/of95-017/

"Infrared Aerial map"

Infrared aerial mapping is when a film or image sensor is used to exposed the sensitivity of infrared light. These photos are taken from above the target and omit a red lighting. This is a map of the Avon Park Air Force Range. http://www.outintheboonies.com/Avon_Park_AFR/

"Cartographic animation map"

Cartographic animation is when the use of animation, normally computer generated, to add a temporal component to a map displaying change in some dimension. The change is shown over time. This map shows the meteorological animation which displays the total precipitation and winds on August 4, 1996. http://50mapsfromericawest.blogspot.com/2011_07_01_archive.html

"Statistical map"

A statistical map is a map that represents graphical information that is put in the form of statistics. The map shows the income percentages of each state in the United States in 2008. It also shows that Michigan has the lowest income level while Hawaii has the highest. http://hoekstrasmaps.blogspot.com/2009_04_01_archive.html

"Cartogram map"

Cartograms are used to display ratios of information such as spending rates, mortality rates, population or consumption rates. This map shows the 1996 Presidential vote results in the United States. http://www.ncgia.ucsb.edu/projects/Cartogram_Central/gallery.html

"Flow map"

Flow maps are used to show the order of an event and the relationships of the stages in the process. In the map you can see the progress of what it would take for someone to go to school. You see in the map it flows from a patient wanting a referral to the front office to the insurance company. It flows from one event to another. http://www.aafp.org/fpm/2005/0400/p61.html

"isoline map"

Isoline maps are used to represent a three dimensional model on a two dimensional scale. This is done by connecting lines that represent the same value. This map shows the weather in the United States. As you can see there are lines across the map and those lines form circles. Each circle has a particular weather in that area, which isn't shown on this map. http://giscommons.org/output/

"Proportional Circle map"

Proportional circle maps use circles to represent different data values. The bigger the circle the more data that is shown in that area. In the map it shows the traffic fatalities in the United States in 2009. http://personal.frostburg.edu/mtmaier0/Symbol_1.jpg" imageanchor="1" >BlogThis!

"Choropleth map"

A choropleth map is a map that uses differences in shading or coloring in an area to represent the average values of a quantity of something in that area. The map shows the Latino population in the state of Florida in 2000. The darker the area the more dense the population. http://my.ilstu.edu/~jrcarter/Geo204/Choro/Tom/

"Dot Distribution map"

A dot distribution is a map that uses dots to portray a feature such as a disease or a something similar to that. In the map it shows how AIDS was distributed in the United States up to 1997. Each dot represents 30 cases of AIDS. This map is a great example of a dot distribution map because it uses dots to describe the distribution of AIDS. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3U8r_T7DUod02M0NRccvdwU2c2aGHBRkxXswKrc-eAvYHDVGFgu8xt1f58_saZnBJKqkydYC8Hw_gVZJqt7ldTdbBgmO7fSFMdJc2T2tD5AWnPHltJZFYxeBci7WrbtbJaylJqZRHcf0/s1600/dot+distribution.png" imageanchor="1" >BlogThis!
