Detailed Description

SngQuadCoo - Quad tree coordinates. This class describes the geographical limits of a quad tree node. The internal coordinate system is based on 32-bits integer spherical coordinates mapping the ranges 0-360 and 0-180 degrees of longitude and latitude.

This class also enacpsulate the uniqe 64-bits ID for each quad tree node. This ID is derived from the parent node and the child direction of each node.

Constructor & Destructor Documentation

QuadCoo()

Maria3D::QuadCoo::QuadCoo ( const QuadCoo &  parent, int  child_dir  )

inline

Construct from parent and child direction. This constructor initializes the quad limits and ID from the parent quad, and the child direction.

Member Function Documentation

getMaxIntE()

Maria::WebMercator::IntCoord Maria3D::QuadCoo::getMaxIntE ( ) const

inline

Return maximum internal East coordinate for the tile. The tile uses an integer coordinate system internally, mapping the degrees to the full range of an unsigned int, in order to have consistent and predictable comparison checks. To get the actual maximum longitude, use getMaxLongitude().

See also

getMaxLongitude()

getMaxIntN()

Maria::WebMercator::IntCoord Maria3D::QuadCoo::getMaxIntN ( ) const

inline

Return maximum internal North coordinate for the tile. The tile uses an integer coordinate system internally, mapping the degrees to the full range of an unsigned int, in order to have consistent and predictable comparison checks. To get the actual maximum latitude, use getMaxLatitude().

See also

getMaxLatitude()

getMinIntE()

Maria::WebMercator::IntCoord Maria3D::QuadCoo::getMinIntE ( ) const

inline

Return minimum internal East coordinate for the tile. The tile uses an integer coordinate system internally, mapping the degrees to the full range of an unsigned int, in order to have consistent and predictable comparison checks. To get the actual minimum longitude, use getMinLongitude().

See also

getMinLongitude()

getMinIntN()

Maria::WebMercator::IntCoord Maria3D::QuadCoo::getMinIntN ( ) const

inline

Return minimum internal North coordinate for the tile. The tile uses an integer coordinate system internally, mapping the degrees to the full range of an unsigned int, in order to have consistent and predictable comparison checks. To get the actual minimum latitude, use getMinLatitude().

See also

getMinLatitude()

getQuadId()

const Maria::TileId & Maria3D::QuadCoo::getQuadId ( ) const

inline

Get the quadtree ID. The quadtree ID is a 64-bits integer ID which is unique for each node in the quadtree.

getTreeLevel()

int Maria3D::QuadCoo::getTreeLevel ( ) const

inline

Return quadtree level. The quadtree level increases with depth, so that level 0 is the root.
