Hardware Compatibility

SoilVision is written in Microsoft Access and is designed to run within Windows 95/98/NT/2000/XP. Optimum performance of the software requires sufficient RAM and fast hard drive access times due to the memory intensive nature of databases. The following hardware platform is suggested.

  • Pentium 266
  • 64 Mb RAM
  • 60 Mb Hard Disk Storage
  • CD ROM Drive

Correlation Database

Unsure of your soils compression index? Interested in the shrinkage limit of your soil? Search our database of correlations gathered from industry verified research. Over 50 graphs and tables are provided, complete with references, for your convenience.


Unlock the full value of your data. Search for hidden correlations between soil parameters. Calculate confidence limits on your normally distributed or logarithmically distributed soil parameters. Interested in the variation of the saturated permeability of Silty Loams? Now you can know.

SoilVision provides you with all the geostatistical methods necessary for the univariate or bivariate analysis of any soil parameter. The mean, standard deviation, or the variance of any soil parameter may be calculated. For univariate analysis, the user can analyze whether a parameter is normally distributed with the Probit plot or analyze confidence limits with the z-test. Statistical calculations can be developed based on a linear or lognormal scale. The user may also check the similarity of data with the autocorrelation function.

Bivariate and coherency analysis allow the user to analyze the relationship between two variables. Users may plot a correlation, perform a spectral analysis, or evaluate a cross-correlation.

SoilVision Introduction

SoilVision Version 3.0 has been redesigned to offer significant improvements on two levels. First, the user interface has been redesigned to offer a Windows standard method of operation. Menu systems replace picture icons and new tab controls offer significant improvements in the grouping of soil data. At a deeper level, improvements have been added to enhance the ability of SoilVision to handle corporate data needs as well as new pedo-transfer functions, curve-fitting, statistical methods, and constitutive relation surfaces to enhance the estimation of saturated and unsaturated soil properties.

SoilVision is the most complete package available for the estimation and/or representation of your unsaturated soil properties. Version 3.0 implements seven pedo-transfer functions for the estimation of the soil-water characteristic curve, eight methods for estimating saturated hydraulic conductivity, and five methods of estimating the unsaturated hydraulic conductivity. Other significant improvements include the ability to mathematically curve-fit bimodal grain-size distributions or bimodal soil-water characteristic curves. Mathematical representations of soil-property functions can be combined in version 3.0 to produce volume change and water content constitutive surfaces representing soil behavior at any soil suction or net normal stress.

The ability to represent soil property functions for the calculation of vapor extraction rates has also been added to SoilVision version 3.0. Users may now calculate volumetric air content or air permeability of a soil at varying suction levels.

Enhancements have been added to SoilVision version 3.0 to meet data management needs on a corporate level. The ability to manage borehole, piezometer, and geochemical data make SoilVision the ideal corporate solution. SoilVision is also the only commercially available database system capable of managing unsaturated soils data. Standardized laboratory reporting has been added to streamline office procedures. Version 3.0 conforms to ASTM and other industry-accepted standards for the representation of sieve analysis, oedometer and isotropic triaxial consolidation tests, shear box and triaxial shear tests, modified and standard Proctor compaction tests, and soil-water characteristic, shrinkage, and permeability data. For the mid-sized firm, version 3.0 allows the development of a corporate database installed on a central server. The results of soil tests may be entered in the laboratory and are then available to the rest of the office for further analysis. For large, multi-office firms, version 3.0 makes use of synchronization to ensure your data is current at each office location. The open-database format of version 3.0 also ensures that the value of your corporate data will never be lost. The ability to handle English or Metric units also offers more flexibility.

SoilVision remains the only commercially available database product which comes with a large existing database of high-quality unsaturated and saturated soils data. The database has been expanded in version 3.0 with new soils data added from research publications and Universities. Shrinkage, compaction, and compression data continue to make the SoilVision database the most complete database currently available. Over 6000 soils are available in version 3.0, and the database is continually growing as more and more people and organizations around the world donate valuable soils data.

Advantages over other database solutions

  • Theoretical estimation of soil properties
  • Pre-existing laboratory database of over 6000 soils
  • Geostatistics module allows quick statistical analysis of your laboratory data
  • Soils data is centralized on a server
  • Only commercial database application in the world capable of managing unsaturated soils information
  • Management of geoenvironmental data
  • Automatic soil texture classification by the USDA or USCS (ASTM) methods
  • Mathematical fits of soil property functions allows soils in certain "bands" to be selected
  • Levels of software implementation allow the software solution to grow as your company grows
  • Globally standardized soils database format which is the same in Access, SQL Server, and Oracle

Query Interface

A capable query interface is critical to unlocking the power of your data. SoilVision provides the most flexible, free-form query wizard currently available in a soils database system. The query wizard can be used to create complex queries across multiple tables. Select all Silty Loam soils with a porosity between 0.30 and 0.42. You will never lose track of subsets of data since queries are stored for later use within SoilVision.
