Northing Easting conversion to Geographic coordinate WGS84
One of my clients requested me to transform 3 coordinates at offshore platform by giving me northing and easting data. I really don't how to convert it and refer to my GURU. For this offshore conversion, experience surveyor will immediately mention UTM projection. What is UTM projection? the Traverse Mercator Projection is widely used in national and international mapping. Please kindly refer to http://en.wikipedia.org/wiki/Transverse_Mercator_projection for information regarding this projection.
After that we need to know the rough location because we need to set the zone when convert the coordinate.
Geodetic Datum Transformation system (GDTS) has the ability to convert above data.
If you have a few data and the conversion able to do it at above website. RCN (Reseach coordinate Network) does a good application and the result similar with GDTS. The link is http://www.rcn.montana.edu/resources/tools/coordinates.aspx?nav=11&c=UTM&md=83&mdt=NAD83/WGS84&z=48&e=451274&n=724132&h=N.
