Star Plot


A star plot allows for the comparison of multiple variables of different types of data. For example, here the model is comparing 1-9 different types of data of 16 different cars. Note the similarities between the Buick Electra and the Cadillac DeVille.

Box Plot


"Box Plot representation of distances covered by First Division Brazilian soccer players (n = 55) according to playing positions after 90 minutes of play, including only those who played the whole game. The players were classified in five positional groups: central defenders (CD, n = 15), external defenders (ED, n = 12), central midfield players (CM, n = 11), external midfield players (EM, n = 9) and forwards (F, n = 8)."
(http://www.jssm.org/vol6/n2/11/F4.htm)
This type of data representation is good in understanding groups of numerical data. It looks like the Central Defender came in first.

DOQQ Map of Coastal Louisiana 2004




A conventional aerial photograph contains image displacements caused by camera lens distortion, camera tip and tilt, terrain relief, and scale. An aerial photograph does not have a uniform scale, therefore, is not a map. The effects of camera tilt and terrain relief are removed through a rectification process to create a computer file referred to as a digital orthophoto. A digital orthophoto is a uniform scale photographic image and can be considered a photographic map.

DRG Maps




DRGs are created by scanning paper maps at 250 pixels per inch resolution. Since at 1:24,000 1 inch on the map represents 2,000 feet on the ground, each DRG pixel corresponds to an area about 8 feet (2.4 meters) on a side. Each pixel is associated with a single attribute: a number from 0 to 12. The numbers stand for the 13 standard DRG colors

Isotach

Isotach maps are a measurement of wind speed, usually measured every hour or more. These lines are called wind bars which indicate wind speed ans wind direction. Note their likeness to a weather vane. The back of the vain is where you will see the smaller bars indicating wind speed. The short bar indicates 5mph/knots, the longer ten mph/knots and a flag indicates 50 plus mph/knots. These barbs help in understanding weather pattern and predicting weather. The wind speed and direction as well as barometric pressure all work together in predicting weather.

Isobars

Isobars are a means to visualize atmospheric pressure. It is a key component in predicting weather. Note the differences in numbers between the high and low pressure fronts. The pressure gradient force is the difference in these numbers between their proximity. The greater the number, the greater the PGF.

LIDAR of the World Trade Center



LIDAR reading of the World Trade Center site. "The use of lasers has become commonplace, from laser printers to laser surgery. In airborne-laser-mapping lidar, lasers are taken into the sky. Instruments are mounted on a single- or twin-engine plane or a helicopter. Airborne lidar technology uses four major pieces of equipment (see figure below). These are a laser emitter-receiver scanning unit attached to the aircraft; global positioning system (GPS) units on the aircraft and on the ground; an inertial measurement unit (IMU) attached to the scanner, which measures roll, pitch, and yaw of the aircraft; and a computer to control the system and store data. Several types of airborne lidar systems have been developed; commercial systems commonly used in forestry are discrete-return, small-footprint systems. “Small footprint” means that the laser beam diameter at ground level is typically in the range of 6 inches to 3 feet. The laser scanner on the aircraft sends up to 100,000 pulses of light per second to the ground and measures how long it takes each pulse to reflect back to the unit."
