Unclassed Choropleth Map
Description: An Unclassed Choropleth Map is one that has an infinite amount of color values. It essentially has no range as a classed choropleth map has. The map on the left above is a classed choropleth map and the one on the right is an unclassed choropleth map. It is very easy to notice that is much more difficult to read the unclassed choropleth map even though it is much more precise in showing actual data values.
Classed Choropleth Map
Description: A Classed Choropleth Map is basically a choropleth map that uses a set number of intervals to display the information within. So, for example, the map above shows the Hispanic population density and it is split up into 5 intervals that the data points may fall within.
Range Graded Proportional Circle Map
Description: Contrary to the Continuously Variable, the Range Graded Proportional Circle Map uses a limited set of circles on there maps to display the data at hand. The only downside is that you have to generalize data based on the closest circle size in the limited set therefore accuracy takes somewhat of a blow. The map above is a map of California and the amount of Motor Vehicle Deaths in different areas.
Continuously Variable Proportional Circle Map
Description: A Continuously Variable Proportional Circle Map is just a variation off of the normal Proportional Circle Map. The only difference really is that there is multiple variables that are being conveyed in each circle or at least the possibility is there. The map above is just a map of how much meat butchers from each area sent to Paris for butchers.

DOQQ
Description: A DOQQ is a digitized map of an aerial photo. Since photographs can be affected by the angle its taken at and the relief caused by the angle of the sun, a DOQQ takes these photos and corrects there flaws digitally.
DEM
Description: A Digital Elevation Model (DEM) is used to show a 3D representation of an area relating to its elevation. It is essentially a 3D model of land elevation using tinting and shade relief. This is a map conveying a volcanic caldera.
DLG
Description: A Digital Line Graph is an option for maps to use be scanned into programs as a vector and then used to generalize topics. It is used in programs such as CAD.
DRG
Description: This is a DRG map of Delaware. A DRG map is essentially just a scanned USGS topographic map used at a specific resolution.
Isopleth Map
Description: This Isopleth map shows the average temperature of the United States for a week in July. An isopleth map generalizes data for areas with a continuous distribution. They are typically viewed when trying to convey things such as precipitation, elevation, and other topics capable of being viewed from a statistical stand point in the third dimension.
Isopach
Description: This is an Isopach Map of Pacifica, California showing the thickness variations of Halocene sediments in an area. Isopach lines are contour lines of equal thickness of sediments.
Isohyet
Description: This is an Isohyet map of India. Isohyet maps are used to determine rainfall amounts and the amount along a connected line has the same amount of rainfall in those areas.
Isotach
Description: This is a map of North America showing wind speed, patterns, and relative temperature to each other. Each connected line has the same wind speed in an Isotach map.
Isobars
Description: This is an Isobar map of the United States. The isobar map helps to distinguish between pressures of highs and lows. You can relate high and low pressure on an Isobar Map depending on the distance between each line.
LIDAR
Doppler Radar
Description: This is a satellite doppler radar view of Florida when Hurricane Francis hit in 2004. The doppler radar tracks cloud motion through tracking its micro wave radiation. One can then calculate a cloud systems reflectivity and velocity using this information.

Topographic Map
Description: Contrasting my last post, this map is a great example of Topographic Map because while it does show direction, it is also conveying elevation through contour lines. That sole difference makes it a Topographic Map rather than a Planimetric. This map is showing a part of New York City being changed.
Planimetric Map
Description: This is a great example of a Planimetric Map because it is showing direction without relation to its environment such as elevation and things like that. It is strictly showing streets and borders, and with this particular map it is showing a section of New York City being changed.
Mental Map
Description: This is a mental map that conveys how one could manage there time throughout each day, week, month, or years to come.
