Sample data or table? It would help to see what you have.
And more importantly, are you talking planar coordinates or geographic?
It is relatively easy to calculate the point coordinates given a distance and bearing/azimuth/angle from a start point.
Once that is accomplished then your distance filter can be applied to return the appropriate angle.
It's a table of a geographic coordinates, and sorry for not mentioning it
before, i want to run this process as an online service.
as i want to send GPS information from mobile phone to GeoProcessing server
for further processes
Yeah.. i thought it would be easier but turned a bit complicated. As i want
to preform the same process to retrive a point from different distances and
angles assigned to a set of points!!
Anyways thank you, i do value your input and yor extended help
