The following code will convert from UTM to longitude latitude
以下代码将从 UTM 转换为经度纬度
<html>
<head>
<script src="proj4.js"></script>
<script>
var utm = "+proj=utm +zone=32";
var wgs84 = "+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs";
console.log(proj4(utm,wgs84,[539884, 4942158]));
</script>
</head>
<body>
</body>
</html>
In this code, the UTM zone is 32, as should be obvious. The Easting is 539884, and the Northing is 4942158. The result is:
在这段代码中，UTM 区域是 32，这应该是显而易见的。东距为 539884，北距为 4942158。结果为：
[9.502832656648073, 44.631671014204365]
Which is to say 44.631671014204365N, 9.502832656648073E. Which I have verifiedis correct.
也就是说 44.631671014204365N，9.502832656648073E。我已经验证是正确的。
If you need other projections, you can find their strings here.
如果您需要其他投影，您可以在此处找到它们的字符串。
