这里地图两点距离计算的单位是什么?

What is the unit of two point distance calculation in here map?

我正在使用 heremap 方法计算两点之间的距离,如下所示:

var pointStart = {
 lat: '40.822197', 
 lng: '-98.188853' 
}

var pointEnd = {
 lat: '43.083113', 
 lng: '-77.589063' 
}
var p1 = new H.geo.Point(pointStart.lat, pointStart.lng);
var p2 = new H.geo.Point(pointEnd.lat, pointEnd.lng);
var dist = p1.distance(p2); 

距离的单位是什么?

是米。您可以在文档中找到它 - https://developer.here.com/documentation/maps/topics_api/h-geo-point.html#h-geo-point__distance

距离(其他):{number}

Returns点与调用者提供的点之间的距离。该方法使用 Haversine 公式。不考虑海拔高度。

参数:

其他: {H.geo.IPoint}

An object representing the point to which to calculate the distance

Returns:

{number} 
A value indicating the distance between the given location and the location supplied by the caller in meters
