Geometry.calculateLength2D介绍

[英]Calculates the length of the geometry. If the spatial reference is a Geographic Coordinate System (a system where coordinates are defined using angular units such as longitude and latitude) then the 2D distance calculation is returned in angular units. In cases where length must be calculated on a Geographic Coordinate System consider the using the geodeticLength method on the GeometryEngine
[中]计算几何图形的长度。如果空间参照是地理坐标系（使用角度单位（如经度和纬度）定义坐标的系统），则以角度单位返回二维距离计算。在必须在地理坐标系上计算长度的情况下，考虑在几何引擎上使用大地测量长度法。
