Destination Calculator — Lat/Lon from Distance & Bearing
Free destination calculator for maps and KML: enter a start latitude/longitude, distance, and bearing to get the destination coordinates. Preview the result on OpenStreetMap and copy lat,lon or KML lon,lat for Google Earth.
Key features
- Calculate destination lat/lon from start point + distance + bearing (0–360°)
- Units: meters, kilometers, miles, feet, and nautical miles
- Copy human lat,lon or KML lon,lat for Google Earth / MultiGeometry work
- Live OpenStreetMap preview of start and destination pins
What the Destination Calculator does
It projects a new geographic point along a great-circle course from your start pin. Enter decimal latitude and longitude, choose a radius distance and true bearing (0° = north, 90° = east), then calculate. The tool returns precise destination coordinates you can paste into KML, Circle Generator workflows, or local SEO coverage maps.
Why local SEO and GBP teams use it
Service-area edges, franchise radius samples, and “X km from store” pins are faster when you can compute a destination instead of guessing on the map. Pair results with Circle Generator for a full ring, or Distance Calculator to verify the span.
How the math works
The calculator uses spherical destination formulas (mean Earth radius 6,371 km) — the same family of math behind Haversine distance and KML circle rings. Longitude is normalized to −180…180 so antimeridian crossings stay valid.
How to use this tool (best practice)
1) Paste your business or center pin as lat, lon. 2) Enter the distance and pick units. 3) Set bearing in degrees. 4) Calculate, copy the destination, and optionally open related Workbench tools for midpoint, bearings, or a full KML circle.
Frequently asked questions
Is this Destination Calculator free?
Yes. It is free on GBP Local Ranker’s KML Workbench at /free-tools/kml-workbench/destination-calculator — no login required for basic use.
What inputs do I need?
A start point as decimal latitude,longitude, a positive distance, a unit (m/km/mi/ft/nm), and a bearing in degrees from true north.
Is bearing magnetic or true?
True bearing for geometry. 0° is north, 90° east, 180° south, 270° west. Magnetic variation is not applied.
Can I use kilometers or miles?
Yes — choose Kilometers, Miles, Meters, Feet, or Nautical miles from the units dropdown.
Do I enter lat,lon or lon,lat?
The start field uses lat, lon (human-friendly). The KML copy line uses lon,lat order for Google Earth.
Is this driving distance / routing?
No. It is geodesic destination math (great-circle), not road routing or traffic travel time.
How do I build a full circle from this?
Use Circle Generator for a 360-point MultiGeometry ring, or run Destination Calculator at many bearings around the same center.
What Earth model is used?
A spherical Earth with mean radius 6,371 km — accurate enough for Google Earth visualization and local coverage maps.
Does it handle the antimeridian (date line)?
Yes. Output longitude is normalized to −180…180 so Pacific crossings remain valid coordinates.
Where are the related tools?
