Classed Choropleth maps

A classed choropleth map utilizes classification techniques to 'break up' intervals, which consist of: equal steps, quantiles, natural breaks and minimum variance. This classed choropleth tells us percentages groups of latinos by counties in Florida.

Range Graded Proportional Circle map

Range-graded proportional circle maps have evenly graded circles to show statistical information. They have set numbers of circle size, in contrast to continously variable poroportional circle maps which have infinite sizes. This map shows Mexican poplulation in the US.

Continously Proportional Circle Map

A continuously variable proportional circle map is a proportional circle map which utilizes circles to create point data. This relates the scales to the specific data. The circles are in proportion to the variable being measured.

DOQQ

Here is a DOQQ(digital orthophoto quadrangle) map of Lake Travis conducted by the University of Texas at Austin, Texas. This was part of an attempt to help create a better floodplain map for Lake Travis and the surrounding area. A DOQQ map is a computer generated image of an aerial photo with geometric qualities of a map.

DEM

DEM is also known as a Digital Elevation Model. Here is a digital representation of the ground surface of Antarctica. They are usually made with remote sensing as opposed to direct surveying through the use of satellites.

DLG

A DLG is a digital line graph, which is a form of a digital map derived from hypographic data. It was developed by the United States Geological survey. The above map is of the Bullcreek Wildlife management area and shows rivers, streams, lakes, wetlands, highways, and back roads.

DRG

Digital Raster Graphics (DRGs) are digitized USGS topo maps. These maps alllow for hybridization with other digital data.

Isopleth

An isopleth map generalizes and simplifies data with a continuous distribution. It shows the data as a third dimension on a map. This isopleth shows germination/growth rates in relation to temp and relative humidity.

Isopach

Isopach maps are frequently used to assist geologists. They map the areal extent and thickness variation of a stratigraphic unit. Here is an isopach map displaying the ash fall from the Cerro Negro Volcano in Nicaragua.

Isohyets

Isohyets are lines connecting points of equal amounts of rainfall. This isohyet map shows rainfall on the coast of Australia.

Isotach

Isotachs connect points off equal wind speed over a given location. This maps shows isobars measured in knots.

Isobars

Isobars are contour lines that connect points of equal barometric pressure. Here is an isobar map in which each blue isobar is 4mb.

LIDAR

LIDAR uses laser pulses to measure scattered light and determine range/distance of distant objects. This LIDAR image is used for archaeology.

Doppler Radar

A Doppler Radar uses the Doppler effect of returned echoes bouncing microwaves off of certain objects to measure their radial velocity. Shown is a doppler image of a tornado.

Black and White Aerial

Black and white aerial photos are photos taken from the sky without color. These photos are good for big places are show texture/shades more clearly than a color or infrared photo. This photo shows a city block.

Infrared Aerial Photo

Infrared aerial photos are sensitive to light in the infrared spectrum and can show us environmental factors/conditions. This infrared aerial shows us vegetation layers (green) and oyster aquaculture areas outlined in red.

PLSS maps

The Public Land Survey System is a manner of dividing and describing US public domain lands through a series of rectangular grid surveys, according to standards set by the Bureau of Land Management. PLSS maps are usually divided into 6 mile square townships, which are then sub-divided into 36 one mile squares.

Cadastral maps are 2-D maps that shows us property and ownership boundaries of land parcels. This cadastral map gives us the boundaries of cities in Deleware County, Ohio.

Thematic maps show spacial patterns of characteristics. These characteristics can be measured qualitatively (i.e soil type) or quantitatively (i.e population density). These thematic maps of California include map themes such as climate (qualitative) and precipitation (quantitative).
