Twelve Orders of Soil Taxonomy

The GLOBE Program is an ” international science and education program that provides students and the public worldwide with the opportunity to participate in data collection and the scientific process, and contribute meaningfully to our understanding of the Earth system and global environment.”

Soil data (investigation of pedosphere) is part of their program. They have compiled a set of documents and protocols on how to measure relevant soil characteristics and evaluate soil quality for their project.

Web Soil Survey

Use this site to investigate local and regional soil maps using data compiled by the NRCS. 


  1. Define an “Area of Interest” under the Area of Interest (AOI) tab. The “state and county” and “address” methods are the easiest. Or you can define your AOI by drawing an AOI box (red box in toolbar) over the area of interest.
  2. Click on the “Soil Data Explorer” Tab to investigate soil properties/qualities and ecological site assessments
  3. Click on “Soil Map” to see a soil map of your AOI
