Week 12: Least Cost Path¶

Presentation Slides¶

Tuesday — Least Cost Path Analysis, Part A — Cost surfaces and the cheapest route across them, with a power-line corridor as the example.
Thursday — Least Cost Path Analysis, Part B — ArcGIS Pro's current tools, Distance Accumulation and Optimal Path As Line; the back direction raster as a compass angle; Lab 11's route computed from its own rules; which decisions moved the line; and a corridor of nearly-as-good routes.

Press F for fullscreen and P for presenter view with speaker notes.

Self-check quizzes — not graded; open them on a phone or laptop as often as you like:

Cheapest or Shortest? — Five questions on cost surfaces, the accumulated cost and back link rasters, and why the cheapest route is usually not the shortest one.
What Moved the Line? — Five questions on the current tools, the back direction raster as a compass angle, which cost factors actually move a route, and what a corridor shows.

Due Saturday at 11:59 pm as one PDF report on Learning Suite — 50 points.

Quiz 10 — Least Cost Paths on Learning Suite: open book, done independently. Due Saturday at 11:59 pm — 20 points.
