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)
Defines tiled raster layout
Defines tiled raster layout
extent covered by the layout tiles, could be greater than extent of data in the layer
tile layout (tile cols, tile rows, tile pixel size)
A LayoutScheme is something that provides LayoutLevels based on an integer id or an extent and cellsize.
A LayoutScheme is something that provides LayoutLevels based on an integer id or an extent and cellsize. The resolution of the tiles for the LayoutLevel returned will not necessarily match the CellSize provided, but an appropriately close selection will be made.
It also provides methods for next zoomed out tile layout level.
Geographic Map Coordinate, uses left is the origin
Transforms between geographic map coordinates and spatial keys.
Transforms between geographic map coordinates and spatial keys. Since geographic point can only be mapped to a grid tile that contains that point, transformation from Extent to GridBounds to Extent will likely not produce the original geographic extent, but a larger one.
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.
Transforms between spatial keys, which always have upper left as origin, to tiling scheme coordinates, which may have different origin and axis orientation.
e.g.: TMS tiling scheme has lower left as it's origin Bing tiling scheme has upper left as it's origin
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.
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.
