This class creates a local Euclidean projection around a given point. This projection may be used to transform geodesic coordinates (LatLonAlt objects) into this Euclidean frame, using the project() method. Also points within this frame, may be found in geodesic coordinates with the inverse() method. As long as the points are close to the projection point, the errors will be very small.
This is mimics the original projection function, and does not try to compensate for being near the poles.
Note: projection objects should never be made directly, and instead should be retrieved via Projection.getProjection()

Destructor
double larcfm::SimpleNoPolarProjection::conflictRange | ( | double | latitude, |
double | accuracy | ||
) | const |
Given an ownship latitude and desired accuracy, what is the longest distance to conflict this projection will support? [m]
LatLonAlt larcfm::SimpleNoPolarProjection::getProjectionPoint | ( | ) | const |
Get the projection point for this projection
Return a LatLonAlt value corresponding to the given Euclidean position
std::pair< Position, Velocity > larcfm::SimpleNoPolarProjection::inverse | ( | const Vect3 & | p, |
const Velocity & | v, | ||
bool | toLatLon | ||
) | const |
Given a velocity from a point in Euclidean 3-space, return a projection of this velocity and the point. If toLatLon is true, the point/velocity is projected into the geodetic coordinate space
Return a LatLonAlt value corresponding to the given Euclidean position
Velocity larcfm::SimpleNoPolarProjection::inverseVelocity | ( | const Vect3 & | s, |
const Velocity & | v, | ||
bool | toLatLon | ||
) | const |
Given a velocity from a point in Euclidean 3-space, return a projection of this velocity. If toLatLon is true, the velocity is projected into the geodetic coordinate space

std::pair< Vect3, Velocity > larcfm::SimpleNoPolarProjection::project | ( | const Position & | p, |
const Velocity & | v | ||
) | const |
Given a velocity from a point, return a projection of this velocity and the point in Euclidean 3-space. If the position is already in Euclidean coordinates, this acts as the idenitty function.
Return a projection of a Position in Euclidean 3-space (if already in Euclidian coordinate, this is the identity function)
Return a projection of a lat/lon(/alt) point in Euclidean 2-space
Return a projection of a Position in Euclidean 3-space (if already in Euclidian coordinate, this is the identity function)
Velocity larcfm::SimpleNoPolarProjection::projectVelocity | ( | const LatLonAlt & | lla, |
const Velocity & | v | ||
) | const |
Given a velocity from a point in geodetic coordinates, return a projection of this velocity in Euclidean 3-space
Velocity larcfm::SimpleNoPolarProjection::projectVelocity | ( | const Position & | ss, |
const Velocity & | v | ||
) | const |
Given a velocity from a point, return a projection of this velocity in Euclidean 3-space (if already in Euclidian coordinate, this is the identity function)
