The Identification of a Least-cost Pathway

The primary purpose of this lab is to work with ArcGIS and to create least-cost pathways. Upon completion of this laboratory I should learn:
1. How to establish proper environmental settings when starting an ArcGIS project, and why that is a useful habit to adopt;
2. How to create a new layer, an address locator, and how to manipulate raster and vector data.
3. How to create a least-cost path.
