Historically, pedologists, armed with shovel, map, color book, and notepad, conducted their work in relative isolation using low-tech methods.� High-tech tools including computers, GIS, and pedon entry and analysis programs are now available to the field pedologist.� Simultaneously, their method of survey has evolved into the Major Land Resource Area (MLRA) concept in which the pedologist works across county and state boundaries with pedologists in adjoining MLRA offices.� Desktop systems do not adequately address data entry, analysis, and dissemination needs for the new type of soil survey office, in part due to the need for a soil scientist to develop a high degree of expertise in programming, and in part due to the difficultly in data exchange and synchronization of highly complex pedon database structures.� The Cooperative Soil Survey website (CSS) is developing an internet-based system that allows the user to classify pedons with advanced, user-friendly tools using soil descriptive properties and associated laboratory analyses.� The certified pedon data is then used to correlate and characterize map units and to produce a new generation of data-driven interpretations.� The processes being developed at the CSS will lead to increasingly dynamic, quantified, and data driven soil survey products sought by the National Cooperative Soil Survey.
