Least Cost Path Hiking Trail Improvement
Least Cost Path Hiking Trail Improvement

In this assignment I was given a current hiking trail and a digital elevation model (DEM) for the area. My task was to create a new hiking trail from the trailhead to the destination using Least Cost Path Analysis with the goal of providing an easier hiking experience. The cost was determined by slope angle, with flatter ground being easier and less costly to traverse. The raster file containing the slope values was created using the DEM. ArcGIS Pro was able to calculate the path with the lowest total cost from the trailhead to the destination. In order to compare and contrast the new and old trails, the slope values at each pixel along both trails were extracted. Using excel, I computed simple statistics for both trails. The mean slope values were significantly lower along the new trail than the current one. The slope variance was also substantially decreased for the new trail. The statistical analysis confirms that the Least Cost Path Analysis was successful in creating a more consistent and level hiking trail. This analysis could be employed with more cost factors, such as land cover, and with an increased number of trailheads and/or destinations.
