Lesson 1 - Downloading Publicly Available Data

Background
There are many data layers available for the public to access via the Internet. For example, the web site of the Nebraska Department of Natural Resources has several essential data layers published. These data cover the entire state of Nebraska and can be downloaded as a series of data files related to specific locations within the state and specific types of data. In this lesson, the three most popular publicly-available data layers are downloaded for an agricultural field at the University of Nebraska-Lincoln Agricultural Research and Development Center located in Saunders County near Mead, Nebraska. The data include: 1) compressed digital orthophoto quad (COQQ), 2) digital elevation model (DEM), and 3) digitized soil survey (SSURGO) map.
