Soil Survey Interpretations Team

Main photo for the Soil Survey Interpretations Team.Overview

Soil survey interpretations is the science of creating models to predict the effect of soil properties on land use. Historically, the models were focused on the land uses directly affecting of humans; however, they have evolved to also quantify how organisms and chemicals interact with soils and landscapes with indirect effects on humans. Currently, a rule-based fuzzy logic system embedded in the National Soil Survey Information System (NASIS) using contemporary soil survey data is the platform for modeling.

The Soil Survey Interpretations Team partners with the Soil Survey Database Team to identify missing or peculiar data. It works with the Initial Mapping Team to learn what new interpretations are needed for areas having unique land uses and ecologies. It also collaborates with the Coastal Zone Soil Survey and Urban Soils Teams to create models that can help land use decisions in those environments. The Soil Survey Interpretations Team, with the collaboration of the Digital Soil Mapping Team, is developing future interpretive models that will use authoritative raster inputs to produce high-resolution, spatially explicit soil performance maps. It works with the Communications and Outreach Team to educate and inform the public on the value of soil survey interpretations.

Science – This group works to determine which soil and site properties affect a land use. They search the literature and anecdotal evidence to discover relationships and interactions that will allow them to establish critical thresholds for how soils and sites control or influence the interactions between land and uses. They then synthesize conceptual models to describe the degree of effect of each variable.

Design and Development – This group works with the rule-based fuzzy logic system in the NASIS Client. They use the concepts provided by the Science Sub-Team to create data extraction and evaluation systems. These systems are used to build the rules and sub-rules that will quantify the degree of suitability or limitation a soil has for the land use being modeled.

Validation – This groups works to thoroughly test interpretive results within the geographic domains of their intended applicability. Because the relative effects of soil properties are often geographic, methodology that identifies and accounts for the differences is needed to make interpretative models that are accurate and equitable.

Documentation – This group will gather the references and rationale used in creating interpretive models, along with images and diagrams describing them, to create documentation brochures for the models. These publications will be made available to the public on an appropriate website.
