On this page: digital soil mapping digital soil mapping Digital Soil Mapping or Predictive Soil Mapping is the computer-assisted production of digital maps of soil type and soil properties.. Digital Soil Mapping can been defined as the creation and population of spatial soil information by the use of field and laboratory observational methods coupled with spatial and non-spatial soil inference systems (McBratney and Lagacherie, Global Workshop on Digital Soil Mapping, Montpellier, 2004).. Digital Soil Mapping makes extensive use of (1) technological advances (e.g.. Digital Soil Mapping can be compared with traditional where soil boundaries are delineated manually and soil maps are typically based on the subjective interpretation by experienced soil surveyors.. In the case of Digital Soil Mapping, various semi-automated techniques and technologies are used to acquire, process and visualize information on soils and auxiliary information, so that the end result is obtained at cheaper costs.

Digital Soil Mapping: Successes, Challenges, and Future Perspectives: The SoLIM Experience.
Friday, 14 July 2006 85-1 Digital Soil Mapping: Successes, Challenges, and Future Perspectives: The SoLIM Experience.. The increased sophistication of spatial analytical techniques and the availability of digital data about the physical landscape have made it possible to develop techniques for digitally and predictively mapping soil spatial variation to improve not only the speed but also the quality and level of detail of soil survey.. This paper examines the current successes, challenges, and future perspectives of digital soil mapping from the experience acquired in developing the SoLIM technology.. We hope that this examination will shed some light on critical aspects of digital soil mapping and thereby assist in the ongoing evolution and development of similar technologies.. There are three major challenges faced by digital soil mapping techniques like SoLIM.. The second challenge, although much progress has been made in this area, is that how we acquire soil-landscape relationship models and insure the quality of these models, which are needed for predictive mapping, particularly for areas with limited physical accessibility.
Random Catena Sampling for Establishing Soil-Landscape Rules for Digital Soil Mapping. Monday, 10 July 2006 12-14 Random Catena Sampling for Establishing Soil-Landscape Rules for Digital Soil Mapping.. Field soil surveyors have suggested that sampling methods that more explicitly explored soil-landscape relationships (such as along the catena) are the most appropriate sampling schemes for establishing mapping rules for digital soil mapping.

. Geographic information systems belong to a family of mapping and drafting programs that includes computer-aided design (CAD) and automated mapping and facilities management (AM/FM).. Mapping scales generally range from 1:12, 000 to 1:63, 360; SSURGO is the most detailed level of soil mapping done by the Natural Resources Conservation Service (NRCS).. This level of mapping is designed for use by landowners, townships, and county natural resource planning and management.
CARES - Projects - Soil Map Digitization Project
. This involves identifying, documenting, and mapping soils; developing this information for publication in the official survey books (usually by county); interpreting soils information for specific applications; and conducting related research.. Work with the Soil Characterization Laboratory to utilize detailed soil information and identify mapping variations in existing soil data.
Moving Soil Surveying into the Digital Age
. Geographical Information Systems are often thought of as automated mapping systems, although they are more accurately described as a powerful set of automated tools for collecting, storing, retrieving, analyzing, transforming, and displaying spatial data.
