The author shares their experiences of accurately mapping their rural property, which they recently purchased. They initially used an app called Map Plus on their iPhone, but found that the accuracy was not sufficient. They then decided to invest in their own survey equipment to achieve centimeter accuracy. They purchased two GPS receivers, one for the base station and one as a rover, and set up their own RTK NTRIP station. They also built a base station in a box using a Raspberry Pi and other components. They successfully established the base station on their property and achieved accurate survey results.
