Core Library
The Core Library is the foundation of
AERALIB® providing class
objects which handle most of the underlying tasks in spherical
geometry, kinematics and numerical methods. The functions are
highly application-independent and are optimized with respect to
both accuracy and execution speed.
The range of components in the Core Library
includes:
- Classes that encapsulate common spherical objects on the sphere
such as locations, great circles, great arcs, small circles, small
arcs, parallels, meridians, spherical polygons, etc.
- Numerical algorithms to solve geometric problems in 4D space,
such as finding intersections between any arc or circle, distances
between locations, projected distances to an arc or circle,
location at a given time or distance along an arc, lead time, time
ahead, overlaps, etc.
- Storage mechanisms to handle more complex structures widely
used in ATC systems. An airspace, for example can be built using
the Spherical Shape class that encapsulates a list of arcs (great
or small).
