Detailed Description

The GeoRect class represents a lon/lat aligned region on the surface of the earth.

Constructor & Destructor Documentation

GeoRect ( )
inline

ctor - sets the GeoRect to contain nothing

Member Function Documentation

bool ContainsPoint ( const GeoCoord &  point) const
inline

Determine if a point is in the GeoRect

bool ContainsPoint ( double  lon,
double  lat 
) const
inline

Determine if a point is in the GeoRect

void GrowToContainPoint ( const GeoCoord &  point)
inline

Increase the area of the GeoRect as needed to include the given point

void GrowToContainPoint ( double  lon,
double  lat 
)
inline

Increase the area of the GeoRect as needed to include the given point

bool Intersects ( const GeoRect &  other) const
inline

Determine if this GeoRect intersects with another GeoRect

bool IsNull ( ) const
inline

determine if the GeoRect to contains nothing

Returns
true if contains nothing else false
void Scale ( const double  scaleFactor)
inline

Scale the region by moving the edges inward or outward from the center.

void SetRect ( double  minLongitude,
