Basics of Data and Information

The first module covered topics such as representing geography, the nature of geographic data, creating and visualizing information, and uncertainty.   This first module allowed for the development of skills using multiple tools, including Hillshade, IDW, Boolean, Greater Than, and Euclidean Distance.

This image of Yellowstone National Park demonstrates how the Hillshade spatial analyst tool to can assess elevation.  Geographic data provided in the attribute table assists with the identification of places and attributes.

This image of the Crafton Hills in Redlands, CA uses the IDW spatial analyst tool with the Samples1 layer to interpolate the data.  This process creates the IDW layer.

This map of Crafton Hills in Redlands, CA uses the Hillshade spatial analyst tool with the interpolated IDW output layer to create hill shade elevation layer.
