Detailed Description

The equirectangular (plate carree) projection.

See also

Equirectangular projection on Wikipedia.

The world and geographic coordinates are related in the following way:

• Latitude between -90 and 90 maps to the Y world axis of the following range: [0, 0.5].
• Longitude between -180 and 180 maps to the X world axis of the following range: [0, 1].
• Altitude maps to the Z world axis and is not scaled.

Member Function Documentation

GetGeoBounds()

GeoRectangle olp::geo::EquirectangularProjection::GetGeoBounds ( ) const

overridevirtual

Gets the geodetic bounds represented by the projection.

Returns

The geodetic rectangle.

Implements olp::geo::IProjection.

Project()

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

overridevirtual

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.

Implements olp::geo::IProjection.

Unproject()

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

overridevirtual

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.

Implements olp::geo::IProjection.

WorldExtent()

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

overridevirtual

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.

Implements olp::geo::IProjection.
