Histogram of Precipitation


This histogram was compared with another in order to understand reflectivity rates for a dual polarization radar. It's all very complicated actually.

Scatter Plot


A scatter Plot is a way to understand continuities or discontinuities between two data sets. Note the plot moving from bottom left to upper right. That indicates a positive correlation. The opposite (top left to bottom right) would indicate a negative correlation.

Unstandardized Choropleth map

This map is not aerially averaged. The data is in raw numbers of people. This is not a very informative map.

Standardized Choropleth map


"The data set consists of 12 ASCII-grids with mean monthly data in mm/day * 10, and one ASCII-grid with yearly data in mm/year."(http://www.fao.org/geonetwork/srv/en/metadata.show?id=5019&currTab=summary) The data is aerially averaged by the 12 grids and the mean monthly and yearly data. and classed in equal intervals of 100 mm/year.

Classed Choropleth



Notice the classes and how they are broken up into intervals of percentage. A map like this gives basic information about populations but can be oversimple.

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.
