P05. (Poster Display) Inverse Least Cost Distance Weighting: Application and Uses

Sign up or log in to save this to your schedule and see who's attending!

AUTHORS: Christopher Dunn, Ramboll Environ

ABSTRACT: Traditional Inverse Distance Weighting (IDW) uses Euclidean distances when weighting values associated with each interpolated raster cell. While this may be the simplest approach computationally, it may not be the most accurate way to represent the complex features and barriers in a real-world system. Using values from a least-cost-distance raster to represent the true distance can result in a more accurate interpolated surface. The poster outlines application methods for Inverse Least Cost Distance Weighting as well as advantages, disadvantages, and applicable situations.
