Now that we’ve explained GNSS and differential correction, we want to talk about ways that you can utilize these technologies for precision farming. GNSS is the basis of many precision ag technologies; it allows you to map and track in-field actions within those field maps. This process is known as georeferencing.

In precision farming, georeferencing refers to the process of associating collected field operation data (such as yield, planting or application data) with specific locations within that field.

Using GNSS to determine your location on Earth allows you to then map what actions you are taking in specific areas of your field. In order for you to receive the most benefit from georeferencing, you need to have accurately mapped information.  As we discussed in our two previous Lessons, accuracy is going to be dependant on the differential source you use.

Georeferenced data is important for several reasons. One of the main uses for your georeferenced data is to view and analyze your inputs in comparison to your outputs on your operation. If you want to know how particular practices are affecting your bottom line, you need to have a system of tracking both inputs and outputs on a common map. Georeferencing allows for you to do this. A good example of this would be if you overlaid a seed hybrid/variety map with a harvest map to determine yield differences.

Georeferencing is the starting point for several precision ag technologies, allowing you to make informed decisions for your future precision farming practices. Therefore, before we discuss these other precision farming practices in future Lessons, it is important that you understand this general concept of georeferencing. Next week, we will discuss how to organize, manage, and analyze your georeferenced data through the use of Geographic Information Systems.
