Common Uses & Real-Life Examples
Measure distance between field sites
Project teams can compare GPS coordinates for two survey, monitoring or service-delivery locations.
Check travel or logistics distances
Logistics staff can estimate straight-line distance between warehouses, offices, facilities or delivery points.
Compare health or education facilities
Analysts can calculate the geographic separation between hospitals, clinics, schools or other public facilities.
Validate GPS data
Unexpectedly large distances can help reveal mistyped, reversed or otherwise incorrect coordinates.
