Mapping Methods

From Introduction to Soil Science by Amber Anderson and Rivka Fidel

Concepts

1. Soil Maps

   "Soil exists mostly underground, so even extensive sampling directly observes only a small portion of the soil landscape. Soil maps therefore predict conditions at unsampled locations using scattered

2. Spatial Association

   "Spatial association uses variables that are easier to observe to infer variables that are more difficult to observe, such as predicting soil properties from matching landscape positions and parent ma

3. GIS

   "Geographic Information Systems are software and hardware systems for storing, manipulating, analyzing, and presenting spatial data. GIS uses layers containing georeferenced objects and values, includ
