使用Openlayers技术加载了高德的底图能否实现测量面积

我想问一下使用Openlayers技术加载了高德的底图能否实现测量面积呢
是否需要调用高德的API？如何实现？

不需要调用高德的api，只需要实现openlayers的面积量测就可以了，官方例子有。调用measure.js，调用方法：

参考这个实现就可以，有帮助请采纳谢谢！

openlayers测距和测面积_qq_41588568的博客-CSDN博客_openlayers 测距初次使用openlayers地图进行开发各种地图功能，测距和测面积使用的是官方例子并进行了一些简单的修改，官方示例在测量一次之后不能停止，修改后，每点击测量，只会测量一次。js文件：measure.jsimport Draw from 'ol/interaction/Draw'import VectorSource from 'ol/source/Vector';import VectorLayer from 'ol/layer/Vector';import TileLayer fro.
