Tutorial on Application of Manifold GIS Software for Precision Agriculture

 Lesson 2 - 3D Display of Integrated Publicly Available Data

There are many data layers available for the public to access via the Internet. These data can give growers valuable information pertaining to spatial variability within an agricultural field. The most popular publicly-available data layers include: 1) digital orthophoto quads, 2) digitized soil survey maps and 3) digital elevation models (see Lesson 1 for more details). Frequently low-yielding areas can be recognized on an orthophoto quad image and/or be related to different soil types and field topography. There is no out-of-pocket expense associated with downloading these types of data. Therefore, the data processing sequence described in this lesson can serve as the first step toward adoption of precision agriculture for a given field. Signs of field anomalies and the presence of high spatial variability may indicate that the field is suitable for additional exploration of the site-specific crop management approach.
