Variety maps are generated on desktop software.   Import planting data from one or more monitors and the data is merged into a variety locator layer for each field.  Write setup cards to one or more combine monitors, and the merged maps can be included.

With Apex, the planting logs must be GS1 or GS2.   With other software that supports writing variety locator files, the planting logs can imported from other color monitors, or even manually drawn.
