| Soil Map | A field that indicates differences in soil factors. |
| Yield Map | Field map showing recorded yield and moisture information as a crop is being harvested. |
| Triangulation | Process that measures your distance to three known satellites, so your location can be mapped based on the intersection of those three points on earth. |
| Singulation | A measure of the percent of seeds being properly metered so that one and only one seed drops from each seed cell of the seed monitor. |
| Skips | A measure of the percentage of seed expected to be planted, but are not planted due to a seed not being dropped by the seed meter, can affect growers yield. |
| Prescription Map | A field map that represents variable rate input prescriptions, often based on yield maps, crop scouting, soil sampling, or other data. |
| Pass-to-Pass Accuracy | Differential correction accuracy within the same day. |
| Manual Guidance | Look at a light bar in front of you to tell where your going and you don't use auto steer. |
| Grid/Sampling Map | A map that shows specific spots in a field where soil sampling or crop scouting will be conducted for analysis. |
| Geographic Information System | Computer system used to collect, manage, and analyze georeferenced field data. |
| Field Mapping | Maps that show site specific data collected from a unique field. |
| Doubles | A measure of the percentage of seed expected to be planted individually, but instead the seed meter drops two or more seeds. Plants too much population, but the skips don't plant enough population. |
| Boundary Map | A field map showing the basic features of your field, including external boundaries and internal boundaries, such as waterways or terraces. |
| AutoSwath | The automatic on/off control of planter sections, boom sections, or area count based on field boundaries, prescription files, or previously applied areas. |
| Automated Steering | Uses a hydraulic system to steer a vehicle along an established path. |
| Assisted Steering | Uses a mechanical steering device installed inside the cab that will work to make sure a vehicle stays on the established path. Assisted steering mechanically moves the wheel of a vehicle |
| As-applied Map | A field map that shows site-specific information about the inputs and rates that have been applied to your field. |
| GPS | A constellation of 24 satellites developed by the US Department of Defense. |
| GNSS | Used to refer to a group of navigational satellites providing signals for global positioning worldwide. |
| Guidance Pattern | The established path your guidance or steering system uses to determine subsequent passes. |
