This question already has an answer here:
I am trying to calculate the point from a given lat/long, a bearing, and a distance.
This is for plotting weather given a aeronautical way point.
Given a waypoint with a known lat/long (LAX airport control tower), with a bearing of North by Northwest and a distance of 45 nautical miles, where is the point?
I could treat the world as flat, but I think the resulting calculations would be inaccurate the further north the point is since longitudes get more narrow near the poles.
I am mainly interested in plotting these points in the US. Is there a projection that would help me do this?
This is for a Python application I'm writing, and the libraries I have access to are GDAL and Proj4 for projections. So no fancy tools like ArcGIS are available to me.
Ultimately I want to combine 4 or these calculated points to form a polygon that should roughly be about 100-200 miles in width and height.
