Grid Coordinate always has the upper left as the origin.
Grid Coordinate always has the upper left as the origin. The tuple always interpreted a (col, row)
A LayoutScheme is something that provides LayoutLevels based on an integer id or an extent and cellsize.
Geographic Map Coordinate, uses left is the origin
Transforms between geographic map coordinates and spatial keys.
Tile Coordinate in a tiling scheme.
Tile Coordinate in a tiling scheme. The origin and axes are defined by the scheme.
Transforms between spatial keys, which always have upper left as origin, to tiling scheme coordinates, which may have different origin and axis orientation.
Tile Coordinate Scheme provides an object that is able to map from a given Tile Coordinate Scheme to a Grid Coordinate, where the origin is upper left corner and tuple (x, y) represents (col, row).
Layout for zoom levels based off of a power-of-2 scheme, used in Leaflet et al.
Layout scheme for dealing with no zoom levels
TODO: This does not seem right! Furthur research shows that TMS tiling actually says that (0,0) is the top left.
This package is concerned with translation of coordinates or extents between:
In order to facilitate these transformations each of the above spaces maps to a "Grid Space" which is a special case of a tiling scheme with the origin defined as upper left and (x, y) coordinate representing (col, row), Java array order.
