VF lines are created in VF software, which requires a digital map of an entire ranch or land management area. Ranchers and land managers may need to collect and verify Geographic Information Systems (GIS) data associated with their area to ensure accurate mapping. GIS data are the digital representation of physical features on Earth’s surface, such as roads, pasture or allotment boundaries, locations of waters, and landmarks. Accurate GIS data are highly beneficial for VF systems and may make it easier to apply precision livestock management across extensive rangelands.
