How this service works
Bounding box (min/max latitude and longitude) enclosing a radius in meters around a point, with pole and 180 degree handling.
Output
Returns a JSON object containing minLat, maxLat, minLon, maxLon defining the bounding box, the radius used, flags indicating whether the bounding box includes a pole (includesPole), crosses the antimeridian (crossesAntimeridian), or spans all longitudes (spansAllLongitudes), the latitude half-height in meters, the ellipsoid model used, a summary, and any disclaimer or degraded-mode notes.
Example use cases
Proximity database query optimization
“I need the min/max lat and lon bounding box around latitude 40.7128, longitude -74.0060 for a 10,000-meter radius so I can filter my database before running an exact distance check.”
Map viewport for circular coverage area
“Can you get me the bounding box that covers a 500,000-meter radius around latitude -77.85, longitude 166.67? I need to know if it hits a pole or wraps around the antimeridian too.”
Geofence boundary for IoT sensor field
“Calculate the geographic bounding box enclosing a 2,000-meter radius around latitude 48.8566, longitude 2.3522 — I need the minLat, maxLat, minLon and maxLon to set up a geofence.”
Technical details
Endpoint
GEThttps://geo-calc.x402tookit.com/bbox-radius?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, edge-case-correct bounding box for a circular radius around a geographic point — especially when the area might span the antimeridian or encompass a pole. It is ideal for pre-filtering spatial database queries, setting map viewports, or defining geofences, and handles the tricky 180° and polar wraparound cases that naive degree-arithmetic approaches get wrong.
Side effects
- Missing required query parameters (lat, lon, radiusM) returns an error
- radiusM outside the 1 to 5,000,000 meter range returns a validation error
- Invalid numeric values for lat or lon return a parse error
- Extremely large radii near poles may return degraded results with warnings in the reasons array
