Questions
Do I need to buy a device?
Not necessarily. Your phone is enough to estimate land area and record approximate locations. For more precise positions, use a compatible RTK receiver and correction service. Dipper Go is in development.
How accurate is phone GPS compared with RTK?
Phone GPS is typically accurate to a few meters in open sky. A compatible RTK receiver with a correction service and internet can provide centimeter-level positions in suitable conditions. Tracing a map depends on the imagery and where you place points.
Can I use it for legal boundary surveys?
No. Our products are for measuring, layout, and record-keeping, and do not replace a licensed land surveyor.
