Type Members

  1. type Cost = (Int, Int, Double)
  2. final class Dir extends AnyRef

    A class encoding directions.

Value Members

  1. def apply(cost: Tile, points: Seq[(Int, Int)]): Tile

    Generate a Cost-Distance raster based on a set of starting points and a cost raster

    Generate a Cost-Distance raster based on a set of starting points and a cost raster

    cost

    Cost Tile (Int)

    points

    List of starting points as tuples

    Note

    Operation will only work with integer typed Cost Tiles (BitCellType, ByteConstantNoDataCellType, ShortConstantNoDataCellType, IntConstantNoDataCellType). If a double typed Cost Tile (FloatConstantNoDataCellType, DoubleConstantNoDataCellType) is passed in, those costs will be rounded to their floor integer values.

  2. val dirs: Array[Dir]
