Optimal Routefinding Across Landscapes Featuring High‐cost Linear Obstacles

摘要: Existing GIS-based least-cost routefinding approaches can in some cases be confounded by linear features the landscape whose crossing costs are high relative to other traversing found throughout landscape. Unfortunately, such high-cost not uncommon; they frequently occur form of hydrologic surrounding dry land. This study (1) enumerates situations where existing fail, (2) proposes a simple method for overcoming limitations approaches, and (3) conducts an experiment assess impact weaknesses magnitude differences between results produced revised approaches. Our show that mountainous terrain, with have profound on routes, choice solution has equally impacts optimal route analysis.
