My question is quite clear:
Assume that there is an ellipse, namely EL1. Parameters of the ellipsoid are (focus11 [latitude, longitude], focus12[latitude, longitude], radius1).
And a second ellipse, namely EL2. Which is defined with the same parameter set (focus21 [latitude, longitude], focus22[latitude, longitude], radius2).
The reference ellipsoid is WGS84.
What is the method to find if EL1 contains EL2 ?
So far the best approach I come up with is to convert the EL1 and EL2 to polygons. But it is quite costly.
Is there any idea? Any help is appriciated. Waiting for your replys ...
