points polar coords new Report this article as Inappropriate to us !!!Login to Reply

Hello


I want your help to create a point feature from table. In the table I haven't x,y coordinates but distance and north azimouth (degrees) from known coordinates (point - center).


Thank you

Are the known points projected already?  If not you could use the equidistant projection for each point.  Otherwise choose something like UTM or Albers. 


I guess I'm not quite understanding the difficulty.

The points are not projected. The distastance that I have is from the center (radar) and north azimouth is the angle round the radar. I have the coordinates of center in wgs84 or greek grid.


Finally I found the solution in this question through  the extention  of arcview  3.2. Distance_Azimuth - dist_az_tools.avx.


Thank
