Detailed Description

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

Constructor & Destructor Documentation

disti::GeoRect::GeoRect ( )
inline

ctor - sets the GeoRect to contain nothing

Member Function Documentation

bool disti::GeoRect::ContainsPoint ( const GeoCoord point) const
inline

Determine if a point is in the GeoRect

bool disti::GeoRect::ContainsPoint ( double  lon,
double  lat 
) const
inline

Determine if a point is in the GeoRect

void disti::GeoRect::GrowToContainPoint ( const GeoCoord point)
inline

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

void disti::GeoRect::GrowToContainPoint ( double  lon,
double  lat 
)
inline

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

bool disti::GeoRect::Intersects ( const GeoRect other) const
inline

Determine if this GeoRect intersects with another GeoRect

bool disti::GeoRect::IsNull ( ) const
inline

determine if the GeoRect to contains nothing

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

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

void disti::GeoRect::SetRect ( double  minLongitude,
double  minLatitude,
double  maxLongitude,
double  maxLatitude 
)
inline

Set the GeoRect value

void disti::GeoRect::SetToIntersection ( const GeoRect rect1,
const GeoRect rect2 
)
inline

void disti::GeoRect::SetToNull ( )
inline

Set the GeoRect to contain nothing.

void disti::GeoRect::SetToPoint ( const GeoCoord point)
inline
