Online Bounding Box (BBOX) Tool
What is a BBOX?
A bounding box defines the smallest rectangular boundary of a geographic area using four coordinate values: minimum longitude, minimum latitude, maximum longitude, and maximum latitude. It is widely used in GIS, web map services, and spatial queries.
- GeoJSON: Uses the [minLon, minLat, maxLon, maxLat] format.
- WMS/WFS: Sent as the BBOX=minLon,minLat,maxLon,maxLat parameter.
- Overpass API: Uses the (minLat,minLon,maxLat,maxLon) format.
How to Use?
Use the rectangle draw tool on the map to select an area, or enter coordinates manually. All BBOX formats are calculated automatically and can be copied with a single click.
Other Tools
For coordinate conversion, use the Coordinate Converter. For area calculation, try the Area Calculator.
Frequently Asked Questions
What is a bounding box used for?
A bounding box defines the rectangular extent of a geographic area. It is used in WMS/WFS map services to request data for a specific area, in Overpass API to query OpenStreetMap data, in spatial database queries for area filtering, and in GeoJSON data to define extent information.
How is the WMS/WFS BBOX format written?
In WMS and WFS services, the BBOX parameter is typically written as BBOX=minLon,minLat,maxLon,maxLat. For example: BBOX=28.5,40.8,29.5,41.2. Note that in some WMS 1.3.0 implementations, the order may change based on the CRS (BBOX=minLat,minLon,maxLat,maxLon).
How do I get a bbox from GeoJSON?
In the GeoJSON specification, the "bbox" property is defined in the [minLon, minLat, maxLon, maxLat] format. You can use libraries like Turf.js with the bbox(geojson) function, or calculate it by finding the min/max values of all coordinates. With this tool, you can also create a GeoJSON-compatible bbox by drawing a rectangle on the map.
