Member Function Documentation

GetGeoBounds()

virtual GeoRectangle olp::geo::IProjection::GetGeoBounds ( ) const

pure virtual

Gets the geodetic bounds represented by the projection.

Returns

The geodetic rectangle.

Implemented in olp::geo::WebMercatorProjection, olp::geo::SphereProjection, olp::geo::IdentityProjection, and olp::geo::EquirectangularProjection.

Project()

virtual bool olp::geo::IProjection::Project ( const GeoCoordinates3d &  geo_point, WorldCoordinates &  world_point  ) const

pure virtual

Checks whether the geographic coordinates (latitude, longitude, altitude) of a point correspond to its world coordinates (x,y,z).

Parameters

geo_point	The point position in geographic coordinates.
world_point	The point position in world coordinates.

Returns

True if the coordinates correspond; false otherwise.

Implemented in olp::geo::WebMercatorProjection, olp::geo::SphereProjection, olp::geo::IdentityProjection, and olp::geo::EquirectangularProjection.

Unproject()

virtual bool olp::geo::IProjection::Unproject ( const WorldCoordinates &  world_point, GeoCoordinates3d &  geo_point  ) const

pure virtual

Checks whether the world coordinates (x,y,z) of a point correspond to its geographic coordinates (latitude, longitude, altitude).

Parameters

world_point	The position in world coordinates.
geo_point	The position in geographic coordinates.

Returns

True if the coordinates correspond; false otherwise.

Implemented in olp::geo::WebMercatorProjection, olp::geo::SphereProjection, olp::geo::IdentityProjection, and olp::geo::EquirectangularProjection.

WorldExtent()

virtual WorldAlignedBox olp::geo::IProjection::WorldExtent ( double  minimum_altitude, double  maximum_altitude  ) const

pure virtual

Creates the extent of world coordinates.

Parameters

minimum_altitude	The minimum altitude in meters.
maximum_altitude	The maximum altitude in meters.

Returns

The extent of world coordinates.

Implemented in olp::geo::WebMercatorProjection, olp::geo::SphereProjection, olp::geo::IdentityProjection, and olp::geo::EquirectangularProjection.
