Index value plot

2009-04-18T21:25:00.000-07:00

An index value plot is another type of visualization map. An index value is plotted on a line graph. This map shows the average steam flow in the US from 1999 to 2008. Its shown on a previously made graph to show how relative the steam flow was. It shows that it was normal.

Population profile

2009-04-18T21:23:00.000-07:00

Population profile maps present a graphic overview of several demographic statistics. In the diagram, the male & female populations in Mobile County in 1998 are shown. The different ages are also shown in different groups.

Triangular plot

2009-04-17T22:29:00.000-07:00

A triangular plot is a plot on three variables, which sum to a constant. The axes of the figure show the estimated fraction of the population intending to vote for each of the major parties; the white circle shows the current estimate from opinion polls. The colored areas show the regions of the plot in which -- under the assumption of uniform national swing -- each of the corresponding major parties would win a majority in Parliament.

Climograph

2009-04-17T21:22:00.000-07:00

A climograph is a type of geovisualization. It is a graphic representation of the relation between temperature and precipitation as plotted at monthly intervals throughout the year. This image shows us the Wet-Dry Tropical / Tropical Savanna climate: Timbo, Guinea, at lat. 10N, West Africa. Looking at the map, we can see that a wet season at time of high sun alternates with an almost rainless dry season at time of low sun.

parallel coordinate graph

2009-04-16T22:23:00.000-07:00

A parallel coordinate graph is used to plot large multivariate datasets. Each Y Axis is labled with a particular baseball statistic The value labled at the top of each Y axis represents the player with the highest value in that category. Each line drawn represents a single player. More precisely, a line is represented by the values of each of a player's statistics.

LIDAR

2009-04-13T22:17:00.000-07:00

LIDAR (Light Detection and Ranging) is an optical remote sensing technology that measures properties of scattered light to find range and/or other information of a distant target. LIDAR produces a highly accurate depiction of the forest floor and tree heights.

Standardized choropleth maps

2009-04-12T21:40:00.000-07:00

Scatter plot

2009-04-12T21:24:00.000-07:00

Scatter plots are similar to line graphs in that they use horizontal and vertical axes to plot data points. However, they have a very specific purpose. Scatter plots show how much one variable is affected by another. Waiting time between eruptions and the duration of the eruption for the Old Faithful geyser in Yellowstone National Park, Wyoming, USA. This chart suggests there are generally two "types" of eruptions: short-wait-short-duration, and long-wait-long-duration.

Stem-and-Leaf Plot

2009-03-21T17:43:00.000-07:00

A stem-and-leaf plot is a display that organizes data to show its shape and distribution. This picture would be a good example, except the new housing starts in the USA could be described as skewed to the right because the higher values are more spread out than the lower values.

Correlation matrix

2009-03-18T17:20:00.000-07:00

A correlation matrix shows the strength and direction of a linear relationship between two random variables. This matrix is a calculated protein correlation matrix for phage T7. Correlated behavior ranges from high(red) to low(blue), and the triangular block of red reflects proteins involved in phage assembly, a highly coordinated process.

DRG

2009-03-16T19:11:00.000-07:00

Digital Raster Graphics (DRGs) are scanned images of U.S. Geological Survey (USGS) topographic maps. The scanned image includes all standard map collar information.
When the DRG is combined with other digital products, such as digital orthophoto quarter quadrangles (DOQQs), or digital elevation models (DEMs), the resulting image provides additional visual information for the extraction and revision of base cartographic information.

Isopach

2009-03-15T17:10:00.000-07:00

An isopach is a contour that connects points of equal thickness. The rainbow contours correspond to thickness of sediment on the ocean floor and the increasingly pink colors represent greater sediment thickness. The brown to red seep gas plume contours were generated from the August, 1996 sonar survey.

Isotach

2009-03-14T16:54:00.000-07:00

Isotachs are lines of equal wind speed. They are most often contoured in the upper levels of the atmosphere, especially at the jet stream level. They are important for locating the jet stream and jet streaks within a jet stream. The green lines in the photo are the isotach lines, showing the different wind speeds along the latitudes of the US.

Cartogram

2009-02-26T16:28:00.000-08:00

A cartogram is a map in which some thematic mapping variable – such as travel time or Gross National Product – is substituted for land area. The geometry or space of the map is distorted in order to convey the information of this alternate variable. There are two main types of cartograms: area and distance cartograms. This cartogram shows Open Europe estimate of total European Union net budget expenditure in euros for the whole period 2007-2013 per capita, based on Eurostat 2007 population estimates.

A statistical map gives a standard statistic of the functional time course over a specified set of periods. This map shows the percentage increase in Internet usage in Africa in the mid 1990’s. The red bars show places where usage has decreased, while light purple shows new usage and aqua shows a high percentage of usage.

Flow map

2009-02-25T16:19:00.000-08:00

Flow maps are a mix of maps and flow charts, that show the movement of objects from one location to another, such as the number of people in a migration, the amount of goods being traded, or the number of packets in a network. In this map, showing the tracking of the West Nile Virus, the virus was tracked back to originating in the Michigan area and is the highest state due to the higher number of confirmed cases. Following the map outward form the Mississippi River, the colors show their proximity to the river while their height shows the number of confirmed cases.

A choropleth map is a thematic map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map, such as population density or per-capita income. This map shows the different margins of victory during the 2002 US elections. The red states and all shades of red are the republican states and the blue states and all shades of blue are the democratic states. The different percentages are expressed as different shades of the principle color.

Topographic Map

2009-01-19T22:06:00.000-08:00

A topographic map shows quantative landscaping information through the use of contour lines. This map is useful because it also shows natural and man made resources such as bodies of water in the surrounding areas or mineral deposits, which is useful for strategical or landscape planning. The different colors and different shades of each color show how deep the water is and how high the mountains are in Albania.

Mental Map

2009-01-11T15:22:00.000-08:00

A mental map is a visual display of how that specific person sees the place, object or issue. For each person this map would be totally different and unique because of our different filters an how we interpret our surroundings. This mental map indicates how a person might connect the world around them with a higher being, God.
