Artificial means of distinguishing smooth-line map unit boundaries : an examination of Oregon soil survey maps

Creator:

Sun, Yulin

Abstract:

Soil is a complex living system with high heterogeneity, which makes locating soil map boundaries a challenge. In traditional soil survey, the placement of soil map boundaries relies largely (at least initially) on identifying the soil-forming factors of biota and topographic relief through stereo aerial photo pairs. Future soil survey...

Merging Field Work with Machine Learning : Exploring Andic Soil Development in the Cascade Range

Creator:

Osterloh, Kristopher Richard

Abstract:

Andic soils (aka Andisols) have unique properties that are important to society. For soil scientists, the genesis and taxonomy of Andisols is often confused because they can form in both volcanic and non-volcanic material. This dissertation seeks to address such confusion by looking at andic soil development in the Cascade...

Scaling, ash-driven bistability, and other agents of soilscape genesis discovered while digitally mapping soils of the Blue Mountains, Oregon

Creator:

Almquist, Vance Warner

Abstract:

This dissertation reports on four related, though separate projects. The first project details the process of carrying out a digitally augmented soil mapping (DSM) effort alongside an ongoing survey in Oregon's Ochoco National Forest (ONF) using a Random Forest algorithm. The second chapter describes a initial soil survey in Oregon's...
