update easting and northing using distance and bearing
Hi,
Could anyone suggest a formula / method for updating eastings and northings using a distance and a bearing?

at a first approach, I think you must always operate coordinates as latitude/longitude and then apply conversion to UTM
When you say Northing & Easting, do you mean Lat/Lon or in some kind of projection?
The following page is one I've gotten a lot of information from. To project a point a given distance & bearing from a given coordinate, you could use the equations to determine destination using Rhumb lines.

Erm, forgot to add the link:

Hi sorry for such a late response to your posts,
The data is on OSGB70 projection, it would be sitting within a variety of GIS applications. Ideally i would like to be able to export it to a xls, csv or dxf then specify a bearing and a distance to update specific points.
Many Thanks
