distance measurement
Gauging spatial separation
Distance measurement is the process of determining how far apart two points are, or the result of that process.
Methods range from physical tools like rulers and tape measures to sophisticated technologies: sonar, radar, laser rangefinders, GPS.
The surveyor took careful distance measurements before drawing the property lines.
