Isopleths

Isopleths maps is continuous distribution that show third dimensions on a map helping to simplify and generalize specific data. The third dimension is shown by a series of lines called isopleths that connect points of an equal value. The difference between the two adjacent isopleths is called the isopleth interval. These maps are common when mapping surface elevations, atmospheric pressure, amounts of perception, and other statistical elements that can be viewed as a third dimension on a map. The map above is the mean annual snow fall which helps to show the impact of the winter.

Isopach

Isopach images use contour lines in order to connect points of equal density or thickness. These images are typically used for geologically imaging, stratigraphing in sediment layers.

DRG

A DRG (digital raster graphic) is a scanned image of a U.S. geological survey topographic map. Typically USGS 7.5-minute quadrangle are the images that are scanned for DRG, but can include any raster graphic as long as it is georeferenced so the images could interlay with one another. The picture above is a DRG showing the western section of Washigton, D.C.

Histogram

A histogram is a bar chart that displays a variation of frequencey by being grouped together in ranges. A histogram will show us the most frequently occuring value, overall range, and the shape of the distribution.

Population Profile

A population profile displays the perecentage of people from a particular age group within that society. The younger the population the wider the population profile is on the bottom. Above is a population profile of the Philippines showing that it has large younger population. Japan for example would look almost opposite to this graph because they have a larger older population than younger.

Climograph

A climograph is graph of climatic conditions such as precipitation and temperature of a given place during a specific range of time. This specific graph above show the precipitation in inches and temperature in Fahrenheit throughout the course of a year broken up by months.

Stem and Leaf Plot

Stem and leaf plots allow you to display the statistical information by revealing its distribution, central tendency and dispersion, without losing any of the outliers. This graph above is a stem and leaf plot representing the different heights for adults.

Box Plot

A box plot is a statistical representation of data broken up to display full range of variation, staring with the minimum going up to a maximum. Also showing the IQR, the likely range of variation, and the median. The IQR is between the first quartile and the third quartile showing the interquartile range.

Circle Proportional Map

This circle proportional map displays seismic activity with location as well as time. This map not only uses cirlces to show seismic intensity but also graduating colors to show the different times. The different sizes of the cirlces for circle proportional maps help to indicate how strong or weak the activity is being displayed.

Choropleth Maps

I chose to use one of the choropleth maps that we were assigned to make for discussion board number seven as my map catalog choropleth map. This map is displaying the different ranges of housing prices based on location. It uses ranges/color graduated as a means of scale. On the right of my map is the scale using the different colors. Much more blues, purples, and greens are seen on this map because that is about the middle of the pricing range or about average.

Thematic Map

The above map describes the average population change in the U.S. from the years 1990-2000. Like the one above, thematic maps differ from general reference maps in that they show or emphasize a particular theme or special topic.

Topographic map

Topographic maps are geographic images that show elevation and depression (rise and fall) of the earth's surface. The most well known examples of Topographic maps that are most widely used are the 1:24,000-scale topographic maps, also known as 7.5-minute quadrangles. These maps were formed by the USGS in 1879 and covered the entire United State's surface.

Planimetric map

The above image is an example of the planimetric map. It is a two dimensional image showing only the horizontal position of features on the earth's surface. These may include natural physical features or man made structures such as roads or buildings. It is important to note that these maps are not topographic and are frequently in planning models such as landscape designs for urban areas.
