Tile
```
public static enum Tile.Location
extends Enum<Tile.Location>
```
Enumerate for point location with respect to the interpolation grid of a tile.
Elevations in a tile are interpolated using the four neighboring points in a grid: (i, j), (i+1, j), (i, j+1), (i+1), (j+1). This implies that a point can be interpolated only if the elevation for these four points is available in the tile. A consequence is that a point in the northernmost row (resp. easternmost column) miss neighboring points at row j+1 (resp. neighboring points at column i+1) and therefore cannot be interpolated.

This enumerate represent the position of a point taking this off-by-one property into account, the value HAS_INTERPOLATION_NEIGHBORS correspond to points that do have the necessary four neighbors, whereas the other values correspond to points that are either completely outside of the tile or within the tile but in either the northernmost row or easternmost column.

- Enum Constant Detail
  - SOUTH_WEST
```
public static final Tile.Location SOUTH_WEST
```
    Location for points out of tile interpolation grid, in the South-West corner direction.
  - WEST
```
public static final Tile.Location WEST
```
    Location for points out of tile interpolation grid, in the West edge direction.
  - NORTH_WEST
```
public static final Tile.Location NORTH_WEST
```
    Location for points out of tile interpolation grid, in the North-West corner direction.
    The point may still be in the tile, but in the northernmost row thus missing required interpolation points.
  - NORTH
```
public static final Tile.Location NORTH
```
    Location for points out of tile interpolation grid, in the North edge direction.
    The point may still be in the tile, but in the northernmost row thus missing required interpolation points.
  - NORTH_EAST
```
public static final Tile.Location NORTH_EAST
```
    Location for points out of tile interpolation grid, in the North-East corner direction.
    The point may still be in the tile, but either in the northernmost row or in the easternmost column thus missing required interpolation points.
  - EAST
```
public static final Tile.Location EAST
```
    Location for points out of tile interpolation grid, in the East edge direction.
    The point may still be in the tile, but in the easternmost column thus missing required interpolation points.
  - SOUTH_EAST
```
public static final Tile.Location SOUTH_EAST
```
    Location for points out of tile interpolation grid, in the South-East corner direction.
    The point may still be in the tile, but in the easternmost column thus missing required interpolation points.
  - SOUTH
```
public static final Tile.Location SOUTH
```
    Location for points out of tile interpolation grid, in the South edge direction.
  - HAS_INTERPOLATION_NEIGHBORS
```
public static final Tile.Location HAS_INTERPOLATION_NEIGHBORS
```
    Location for points that do have interpolation neighbors.
    The value corresponds to points that can be interpolated using their four neighboring points in the grid at indices (i, j), (i+1, j), (i, j+1), (i+1), (j+1). This implies that these points are neither in the northernmost latitude row nor in the easternmost longitude column.
- Method Detail
  - values
```
public static Tile.Location[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (Tile.Location c : Tile.Location.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static Tile.Location valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
