google 地图 api 中的样式化 geojson 点
styling geojson point in google maps api
我正在使用 google 地图 api 和一个 geojson 数据文件进行地图项目。我的问题是我不知道如何将自定义样式应用于我的观点。这是我加载数据的方式:
<script>
var map;
function initMap() {
map = new google.maps.Map(document.getElementById('map'), {
zoom: 11,
center: {lat: 43.15, lng: -84.75}
});
map.data.loadGeoJson(
'Maps/Newark.geojson');
map.data.loadGeoJson('Maps/Newark.geojson');
map.data.setStyle(//* I'm not sure what to put here*//)
}
</script>
这是我的 geojson 文件的示例:
{
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [ -84.69729,43.24808 ]
},
"properties": {}
},
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [ -84.58872,43.23395 ]
},
"properties": {}
}
}
要将标记的样式设置为自定义图标,请使用 Data.StyleOptions 对象(如果您为图标提供字符串,它会将其视为 URL):
map.data.setStyle({
icon: "http://maps.google.com/mapfiles/ms/micons/blue.png"
});
代码片段:
var map;
function initMap() {
map = new google.maps.Map(document.getElementById('map'), {
zoom: 9,
center: {
lat: 43.15,
lng: -84.75
}
});
map.data.addGeoJson(geoJson);
map.data.setStyle({
icon: "http://maps.google.com/mapfiles/ms/micons/blue.png"
});
}
google.maps.event.addDomListener(window, "load", initMap);
var geoJson = {
"type": "FeatureCollection",
"features": [{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [-84.69729, 43.24808]
},
"properties": {}
},
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [-84.58872, 43.23395]
},
"properties": {}
}
]
};
