Question

如何从坐标纬度，经度获得地点类型？

当我阅读下面的网址时，可以完成。但在这里我无法传递坐标作为输入（对于变量名称功能）。请有人指导我怎么做。

https://developers.google.com/maps/tutorials/customizing/custom-markers

var iconBase = 'https://maps.google.com/mapfiles/kml/shapes/';
var icons = {
  parking: {
    icon: iconBase + 'parking_lot_maps.png'
  },
  library: {
    icon: iconBase + 'library_maps.png'
  },
  info: {
    icon: iconBase + 'info-i_maps.png'
  }
};

function addMarker(feature) {
  var marker = new google.maps.Marker({
    position: feature.position,
    icon: icons[feature.type].icon,
    map: map
  });
}

我的要求是在google中显示自己的图标坐标。这意味着，如果坐标属于医院，那么我应该显示医院图标....就像这样。

所以，如果我从它的坐标知道地方类型，那么我认为可以做到。

也可以任何人给我一个地方类型及其图像的映射。

...谢谢

是的，你真的可以这样做。

我不知道这是否是最佳解决方案。如果您有坐标（纬度，经度），请使用您自己的API KEY将这些坐标传递给此GOOGLE PALCE API。

https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522,151.1957362&radius=500&types=food&name=harbour&sensor=false&key=AddYourOwnKeyHere

API键是您自己的GOOGLE PLACE API键
