PyPI Introduces Digital Attestations to Strengthen Python Package Security
PyPI now supports digital attestations, enhancing security and trust by allowing package maintainers to verify the authenticity of Python packages.
@turf/bbox
Advanced tools
@turf/bbox is a module from the Turf.js library that calculates the bounding box (bbox) for a given GeoJSON object. A bounding box is an array that defines the minimum and maximum coordinates in the form [minX, minY, maxX, maxY]. This is useful for spatial analysis, mapping, and geographic data processing.
Calculate Bounding Box
This feature calculates the bounding box for a single point. The output is an array representing the bounding box.
const turf = require('@turf/turf');
const point = turf.point([102.0, 0.5]);
const bbox = turf.bbox(point);
console.log(bbox); // Output: [102, 0.5, 102, 0.5]
Bounding Box for a Polygon
This feature calculates the bounding box for a polygon. The output is an array representing the bounding box.
const turf = require('@turf/turf');
const polygon = turf.polygon([[
[100.0, 0.0],
[101.0, 0.0],
[101.0, 1.0],
[100.0, 1.0],
[100.0, 0.0]
]]);
const bbox = turf.bbox(polygon);
console.log(bbox); // Output: [100, 0, 101, 1]
Bounding Box for a Feature Collection
This feature calculates the bounding box for a feature collection containing multiple points. The output is an array representing the bounding box.
const turf = require('@turf/turf');
const point1 = turf.point([102.0, 0.5]);
const point2 = turf.point([103.0, 1.0]);
const featureCollection = turf.featureCollection([point1, point2]);
const bbox = turf.bbox(featureCollection);
console.log(bbox); // Output: [102, 0.5, 103, 1]
The geojson-bbox package provides similar functionality to @turf/bbox by calculating the bounding box for GeoJSON objects. It is a lightweight alternative but does not offer the extensive suite of geospatial tools available in the Turf.js library.
The bbox package is another alternative that focuses on calculating bounding boxes for various types of GeoJSON objects. It is simpler and more focused compared to @turf/bbox, which is part of a larger geospatial analysis library.
Takes a set of features, calculates the bbox of all input features, and returns a bounding box.
Parameters
geojson
(FeatureCollection | Feature<any>) input featuresExamples
var line = {
"type": "Feature",
"properties": {},
"geometry": {
"type": "LineString",
"coordinates": [[-74, 40], [-78, 42], [-82, 35]]
}
}
var bbox = turf.bbox(line);
//addToMap
var bboxPolygon = turf.bboxPolygon(bbox);
var addToMap = [line, bboxPolygon]
Returns Array<number> bbox extent in [minX, minY, maxX, maxY] order
