ArrayTile provides access and update to the grid data of a tile.
ArrayTile provides access and update to the grid data of a tile. Designed to be a near drop-in replacement for Array in many cases.
ArrayTile based on an Array[Byte] as a bitmask; values are 0 and 1.
ArrayTile based on an Array[Byte] as a bitmask; values are 0 and 1. Thus, there are 8 boolean (0 / 1) values per byte in the array. For example, Array(11, 9) corresponds to (0 0 0 0 1 0 1 1), (0 0 0 0 1 0 0 1) which means that we have 5 cells set to 1 and 11 cells set to 0.
Note that unlike the other array-based raster data objects we need to be explicitly told our size, since length=7 and length=8 will both need to allocate an Array[Byte] with length=1.

The Raster type.
RasterExtent objects represent the geographic extent (envelope) of a raster.
RasterExtent objects represent the geographic extent (envelope) of a raster.
The Raster extent has two coordinate concepts involved: map coordinates and grid coordinates. Map coordinates are what the Extent class uses, and specifies points using an X coordinate and a Y coordinate. The X coordinate is oriented along west to east such that the larger the X coordinate, the more eastern the point. The Y coordinate is along south to north such that the larger the Y coordinate, the more Northern the point.
This contrasts with the grid coordinate system. The grid coordinate system does not actually reference points on the map, but instead a cell of the raster that represents values for some square area of the map. The column axis is similar in that the number gets larger as one goes from west to east; however, the row axis is inverted from map coordinates: as the row number increases, the cell is heading south. The top row is labeled as 0, and the next 1, so that the highest indexed row is the southern most row of the raster. A cell has a height and a width that is in terms of map units. You can think of it as each cell is itself an extent, with width cellwidth and height cellheight. When a cell needs to be represented or thought of as a point, the center of the cell will be used. So when gridToMap is called, what is returned is the center point, in map coordinates.
Map points are considered to be 'inside' the cell based on these rules:
Note that based on these rules, the eastern and southern borders of an Extent are not actually considered to be part of the RasterExtent.

A strategy to use when constructing a grid that will be used during resampling
A strategy to use when constructing a grid that will be used during resampling
Various tradeoffs exist when attempting to resize an image. Subclasses of ResampleTarget encode these various tradeoffs in terms of the proportions/alignment desired at the end of resampling. E.g. TargetCellSize tells any resampling function to resample in such a way as to approximately match the specified CellSize in any resulting operations.
This trait is how subclasses define the necessary pieces that allow us to abstract over each of the combine functions

Resample, aiming for a grid which has the provided CellSize
Resample, aiming for a grid which has the provided CellSize
Targetting a specific size for each cell in the grid has consequences for the Extent because e.g. an extent's width *must* be evenly divisible by the width of the cells within it. Consequently, we have two options: either modify the resolution to accomodate the output extent or modify the overall extent to preserve the desired output resolution. Fine grained constraints on both resolution and extent will currently need to be managed manually.
