有直接的解决办法吗?
据我所知,Google Maps API 和特别是全景视图没有像您在帖子中那样在图像的北边和/或南边有箭头的界面。
这样的解决方案必须由您手动编码才能弄清楚。
解决方法
但是,您可以使用一种解决方法,它利用全景视图并且在界面中具有内置指南针。这样,当您四处移动图像时,您总能感觉到南北在哪里。
代码和文档
你可以使用下面的例子来实现这种类型的接口(PS:替换API密钥!):
<!DOCTYPE html>
<html>
<head>
<title>Custom Street View panoramas</title>
<meta charset="utf-8">
<style>
/* Always set the map height explicitly to define the size of the div
* element that contains the map. */
#map {
height: 100%;
}
/* Optional: Makes the sample page fill the window. */
html, body {
height: 100%;
margin: 0;
padding: 0;
}
</style>
</head>
<body>
<div id="map"></div>
<script>
function initPano() {
// Set up Street View and initially set it visible. Register the
// custom panorama provider function. Set the StreetView to display
// the custom panorama 'reception' which we check for below.
var panorama = new google.maps.StreetViewPanorama(
document.getElementById('map'), {
pano: 'reception',
visible: true,
panoProvider: getCustomPanorama
});
}
// Return a pano image given the panoID.
function getCustomPanoramaTileUrl(pano, zoom, tileX, tileY) {
// Note: robust custom panorama methods would require tiled pano data.
// Here we're just using a single tile, set to the tile size and equal
// to the pano "world" size.
return 'https://developers.google.com/maps/documentation/javascript/examples/full/images/panoReception1024-0.jpg';
}
// Construct the appropriate StreetViewPanoramaData given
// the passed pano IDs.
function getCustomPanorama(pano, zoom, tileX, tileY) {
if (pano === 'reception') {
return {
location: {
pano: 'reception',
description: 'Google Sydney - Reception'
},
links: [],
// The text for the copyright control.
copyright: 'Imagery (c) 2010 Google',
// The definition of the tiles for this panorama.
tiles: {
tileSize: new google.maps.Size(1024, 512),
worldSize: new google.maps.Size(1024, 512),
// The heading in degrees at the origin of the panorama
// tile set.
centerHeading: 105,
getTileUrl: getCustomPanoramaTileUrl
}
};
}
}
