    Sammanfattning : Given a grid of cells, each of which is assigned a numerical value quantifying its utility (or cost) for a certain use, a popular type of problem in geographic information science is raster-based spatial optimization. Such problems commonly seek to find a set of cells that maximizes (or minimizes) that utility (or cost) while adhering to a given set of constraints. LÄS MER

    Sammanfattning : Given a grid of cells, each having a value indicating its cost per unit area, a variant of the least-cost path problem is to find a corridor of a specified width connecting two termini such that its cost-weighted area is minimized. A computationally efficient method exists for finding such corridors, but as is the case with conventional raster-based least-cost paths, their incremental orientations are limited to a fixed number of (typically eight orthogonal and diagonal) directions, and therefore, regardless of the grid resolution, they tend to deviate from those conceivable on the Euclidean plane.
