检查点是否在OpenLayers 3中的多边形内 [英] Check if a point is inside polygon in OpenLayers 3

问题描述

当我在OpenLayers地图中绘制多边形时，我想知道标记是否在多边形内.我搜索了OpenLayers API，但没有找到解决方案.

When I draw a polygon in an OpenLayers map, I want to know if the marker is inside the polygon or not. I searched in the OpenLayers API, but didn't find a solution.

我觉得我必须修改此功能:

I have the impression that I have to modify this function:

  function addInteraction() {
    var value = typeSelect.value;
    if (value !== 'None') {
    draw = new ol.interaction.Draw({
      source: vectorSource,
      type: /** @type {ol.geom.GeometryType} */ (typeSelect.value)
    });
    map.addInteraction(draw);
    draw.on('drawend',function(e){
      //Here
    });
  }
}

我该怎么做?

推荐答案

您有一个方法'

You have a method 'intersectsCoordinate' for the ol.geom.Geometry.

因此该代码如下:

var polygonGeometry = e.feature.getGeometry();
var coords = iconFeature.getGeometry().getCoordinates();
polygonGeometry.intersectsCoordinate(coords)
