| |
| If there is a decision expression, then only
| |
| those cells for which this expression returns
| |
| TRUE will be included.
| |
| | |
| DistanceType is either CARDINAL or EUCLIDEAN (the default). Cardinal distance between two cells is the minimum number of cardinal steps (up, down, left, right) to reach one cell from the other. Euclidean distance is the straight-line distance between two points. The WRAPPED flag, if present indicates that the region wraps around the sides (vertically and horizontally) of the landscape (e.g. a location x positions beyond the right-hand side of a raster will be mapped to x positions in from the left-hand side of the raster). If not present, the landscape does not wrap.

| ==REGION LEAST COST PATH==(StartLocation, EndLocation, LeastCostNeighbs, AnchorLoc)
| |
| DECISION Expr
| |
| Defines a region with cells that approximate
| |
| the least-cost path between two cells. The
| |
| first generates the cost function internally.
| |
| The latter two use input information from a
| |
| pre-computed cost surface region. Providing
| |
| both the gradient and anchor location layers
| |
| provides the most accurate approximation.
| |
| | |
| Iteration is a common aspect of models (even if it is very procedural). Most programming languages offer a “for-loop” of some kind. SELES presently provides “over index sequence” expressions as a slightly more declarative (although also more cumbersome) expression for iterating. While-loops can also be used.
