正如您在下面看到的,我有兩個具有邊的多邊形。基本上2個三角形與他們各自的座標。請參閱:使用Google Maps API合併多邊形
function initialize() {
// Define the LatLng coordinates for the polygon's path.
var bounds = new google.maps.LatLngBounds();
var i;
var polygonCoords = [
new google.maps.LatLng(25.774252, -80.190262),
new google.maps.LatLng(18.466465, -66.118292),
new google.maps.LatLng(32.321384, -64.757370)
];
for (i = 0; i < polygonCoords.length; i++) {
bounds.extend(polygonCoords[i]);
}
var map = new google.maps.Map(document.getElementById("map_canvas2"), {
zoom: 4,
center: bounds.getCenter(),
mapTypeId: "roadmap"
});
var triangle1 = new google.maps.Polygon({
paths: polygonCoords,
strokeColor: '#0000ff',
strokeOpacity: 0.8,
strokeWeight: 2,
fillColor: '#0000ff',
fillOpacity: 0.35
});
triangle1.setMap(map);
var polygonCoords2 = [
new google.maps.LatLng(25.774252, -80.190262),
new google.maps.LatLng(18.466465, -66.118292),
new google.maps.LatLng(14.979063, -83.500871)
];
var triangule2 = new google.maps.Polygon({
paths: polygonCoords2,
strokeColor: '#0000ff',
strokeOpacity: 0.8,
strokeWeight: 2,
fillColor: '#0000ff',
fillOpacity: 0.35
});
triangule2.setMap(map);
}
#map {
height: 100%;
}
/* Optional: Makes the sample page fill the window. */
html,
body {
height: 100%;
margin: 0;
padding: 0;
}
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js"></script>
<body onload="initialize()">
<div id="map_canvas2" style="height: 100vh; width:100vw"></div>
</body>
我想,這樣的風險不會出現在兩者之間的中間,從而使多邊形與4個邊或4個座標合併兩個三角形。什麼是最好的方法來做到這一點?
更換
paths: polygonCoords,
是它預計是到座標被合併爲一個(即在波多黎各和佛羅里達州的點)總是相同的座標只是不同折線的一部分?希望這是有道理的 –
