Is there a way to convert UTM to Lat/Long in Javascript? I have seen another thread on this bu开发者_StackOverflowt it was in Java and Python which won't help me much. Please let me know, thanks.
You could use Proj4js, as follows.
Download Proj4JS from GitHub, using this link.
The following code will convert from UTM to longitude latitude
<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:
[9.502832656648073, 44.631671014204365]
Which is to say 44.631671014204365N, 9.502832656648073E. Which I have verified is correct.
If you need other projections, you can find their strings here.
