What is @turf/midpoint?
@turf/midpoint is a module within the Turf.js library that provides geospatial analysis tools. Specifically, @turf/midpoint calculates the geographical midpoint between two points. This can be useful in various applications such as mapping, navigation, and geographic data analysis.
What are @turf/midpoint's main functionalities?
Calculate Midpoint
This feature calculates the geographical midpoint between two points. The code sample demonstrates how to use the @turf/midpoint module to find the midpoint between two given coordinates.
const turf = require('@turf/turf');
const point1 = turf.point([-75.343, 39.984]);
const point2 = turf.point([-75.534, 39.123]);
const midpoint = turf.midpoint(point1, point2);
console.log(midpoint);
Other packages similar to @turf/midpoint
geolib
Geolib is a library for geospatial calculations. It provides various functions for distance, area, and other geographic calculations. Compared to @turf/midpoint, Geolib offers a broader range of geospatial functions but may not be as specialized in geospatial analysis as the Turf.js library.
geodesy
Geodesy is a library for geodesic calculations. It includes functions for calculating distances, bearings, and midpoints between geographic coordinates. While it offers similar functionality to @turf/midpoint, it focuses more on geodesic calculations and less on broader geospatial analysis.
@turf/midpoint
midpoint
Takes two points and returns a point midway between them.
The midpoint is calculated geodesically, meaning the curvature of the earth is taken into account.
Parameters
Examples
var pt1 = {
"type": "Feature",
"properties": {},
"geometry": {
"type": "Point",
"coordinates": [144.834823, -37.771257]
}
};
var pt2 = {
"type": "Feature",
"properties": {},
"geometry": {
"type": "Point",
"coordinates": [145.14244, -37.830937]
}
};
var midpointed = turf.midpoint(pt1, pt2);
midpointed.properties['marker-color'] = '#f00';
var result = {
"type": "FeatureCollection",
"features": [pt1, pt2, midpointed]
};
Returns Feature<Point> a point midway between pt1
and pt2
