LIDAR

This map is showing LIDAR data of the historic Jamestown and Williamsburg area. LIDAR stands for Light Detection and Ranging. It is a remote sensing technology that measures scattered light to finde the distance of a target.

Dopplar Radar

Doppler radar is a radar using the doppler effect of the returned echoes from targets to measure their distance and consistancy. They are commonly used in weather.

Conic Map Projection

This is a conic map projection; it is a projection of a sphere onto a cone. It is a good projection to understand the upper latitudes but the mid- lower latitudes are distorted.

cylindrical projection

This is a cylindrical projection of a globe. It is projected as if a light is in the center of the globe and the globe in a cylindrical container to which it projects on. This is specifically a Mercator projection. It has errors as well though, the poles are distorted larger than they really are and the equator is accurately portrayed.

Isobars

Isobars are lines that connect points of equal pressure. They are used primarily when examining weather since pressure highly influences changes in weather conditions. In this map the L represents an area of low pressure surrounded by bands of increasingly higher pressure.

Scatter Plot

This is a scatter plot it shows the intersection of two axis just like in the histogram. The difference is that this shows a range of data where the histogram shows the frequency of certain units. A scatter plot can have no correlation and be completely scattered, linear and fall in a perfect line, or in a linear correlation that has a general slope but not perfectly linear.

Histogram

A histogram is a graph using an x and y axis to plot the intersection of two sets of data. In this map it is showing the frequency to which a certain event happens. It also shows the range, maximum, and minimum and it allows for an average to be derived as well as a standard deviation.
