GPS/GNSS accuracy varies
The position reported by a phone is an estimate.
Trees, buildings, machinery, terrain, weather, satellite availability and even the way the phone is being held can affect a reading.
For a better result, give the phone time to settle under open sky and keep it still while recording an important point.
Repeat an important measurement if something doesn't look right.
The number of decimal places shown on screen does not mean the real-world position is accurate to the same level.
Not for deciding legal boundaries
AcreTrace is intended for practical field measurement and record keeping.
Do not use an AcreTrace measurement as a legal determination of ownership, title or a cadastral boundary.
Where a boundary has legal or financial importance, use an appropriately qualified surveyor and suitable surveying equipment.
Markers do not locate buried services
AcreTrace can help you remember an approximate location.
It cannot tell you that it is safe to dig there.
Never excavate solely from an AcreTrace pipe, drain or other buried-service marker.
Use current plans, appropriate locating equipment and proper safe-dig procedures before excavation.
Keep your attention on the field
A phone screen is rarely the most dangerous thing around you.
Stop somewhere safe before operating AcreTrace and stay aware of:
- livestock
- moving vehicles and machinery
- water and ditches
- steep drops
- rough or uneven ground
- electric fencing and other field hazards
Don't enter unsafe ground or trespass simply to improve a measurement.
And don't rely on your phone as emergency equipment.
Reports record what was measured
AcreTrace reports preserve the points, accuracy information and notes recorded during field work.
They provide a useful record of what was captured and calculated.
They do not certify that a measurement is legally or professionally exact.
