Detailed Description

Converts the x and y indices of tiles to and from geo coordinates.

For tiles of maps in Equirectangular projection.

Tiles do have the same width and the same height per zoomlevel. The number of tiles per dimension is twice that of the previous lower zoomlevel. The indexing is done in x dimension eastwards, with the first tiles beginning at -180 degree and an x value of 0 and the last tiles ending at +180 degree, in y dimension southwards with the first tiles beginning at +90 degree and a y value of 0 and the last tiles ending at -90 degree.

◆ geoCoordinates() [1/3]

GeoDataLatLonBox Marble::GeoSceneAbstractTileProjection::geoCoordinates

Get the boundary geo coordinates corresponding to a tile.

If tildId has values out-of-bounds, the behaviour is undefined.

Parameters
tileIdthe id of the tile
Returns
geographic bounding box covered by the given tile

◆ geoCoordinates() [3/3]

virtual GeoDataLatLonBox Marble::GeoSceneAbstractTileProjection::geoCoordinates

Get the boundary geo coordinates corresponding to a tile.

If x, y or zoomLevel have values out-of-bounds, the behaviour is undefined.

Parameters
zoomLevelthe zoomlevel of the tile
xthe x index of the tile
ythe y index of the tile
Returns
geographic bounding box covered by the given tile
