}

A helper class for mapping coordinates to tiles and back.

  • Calculates the map tile corresponding to specified point and zoom level.

    Declaration

    Objective-C

    + (NTMapTile *)calculateMapTile:(NTMapPos *)mapPos
                           zoom:(int)zoom
                           proj:(NTProjection *)proj;

    Parameters

    mapPos

    Coordinates for the point.
    zoom

    Zoom level for the tile.
    proj

    The projection to use for tile and point.

    Return Value

    The corresponding map tile.

  • Calculates origin coordinates for the given map tile.

    Declaration

    Objective-C

    + (NTMapPos *)calculateMapTileOrigin:(NTMapTile *)mapTile
                                proj:(NTProjection *)proj;

    Parameters

    mapTile

    The map tile to use.
    proj

    The projection to use for origin.

    Return Value

    The corresponding tile origin.

  • Calculates bounds for the given map tile.

    Declaration

    Objective-C

    + (NTMapBounds *)calculateMapTileBounds:(NTMapTile *)mapTile
                                   proj:(NTProjection *)proj;

    Parameters

    mapTile

    The map tile to use.
    proj

    The projection to use for bounds.

    Return Value

    The corresponding tile bounds.

  • Undocumented

    Declaration

    Objective-C

    -(void)dealloc;
