Four kinds of map units are used in soil surveys: consociations, complexes, associations, and undifferentiated groups. Field investigations and data collection are carried out in sufficient detail to name map units and to identify accurately and consistently areas of about 5 acres. NJDEP assumes no responsibility to maintain them in any manner or form. The U.S. Department of Agriculture, Natural Resources Conservation Service should be acknowledged as the data source in products derived from this data. 3. The depicted soil boundaries, interpretations, and analysis derived from them do not eliminate the need for onsite sampling, testing, and detailed study of specific sites for intensive uses. ratings and suitability ratings) for soil components, LAYER.DBF- (soil layer)- stores characteristics of soil layers for soil components, MAPUNT.DBF- (map unit)- stores information that applies to all components of a Soil Surv. National Soil Survey Handbook, title 430-VI. Adherence to National Cooperative Soil Survey standards and procedures is based on peer review, quality control, and quality assurance. (current issue). An SDE feature data set was then created from the county coverages with the additional items from the MAPUNIT.lut. MUSYM is an abbreviation for Map Unit Symbol. Thus, these data and their interpretations are intended for planning purposes only. They occur in a regularly repeating pattern. variables in SSURGO. ssurgo2008.spatialver,ssurgo2008.musym,ssurgo2008.muname,ssurgo2008.mukey, The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. Contact NJDEP Metadata and Process Contact with any questions regarding NJDEP production processing. ssurgo2008comp.comppct_l,ssurgo2008comp.comppct_r,ssurgo2008comp.comppct_h, Several attribute items were dropped from the SDE COMPONENT table. The DROPITEM command was used to drop all items except MUKEY,MUSYM, MUNAME, MUKIND and LKEY from the MAPUNIT.lut. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information.

The soil map units are linked to attributes in the National Soil Information System relational database, which gives the proportionate extent of the component soils and their properties. Undifferentiated groups - Undifferentiated groups consist of two or more components that do not always occur together in the same delineation, but are included in the same named map unit because use and management are the same or similar for common uses. For additional information, see the References section and the Data Source Contact section of this documentation. Attributes include table and column descriptions and detailed domain information. Serv. Digital data received from the NJDEP may not be reproduced or redistributed for use by anyone without first obtaining written permission from the NJDEP. This soil survey depicts information about the kinds and These tables were not developed for this county by the NRCS. Vector datasets with no defined scale or accuracy should be considered suspect. SSURGO represents over 100 years of work by many soil scientists. A single component of a dissimilar limiting inclusion generally does not exceed 10 percent if very contrasting. Make sure you are familiar with your data before using it for projects or analysis. A blank feature class and feature data set were created, and then each county coverage loaded into the new feature class using the LOAD DATA option in ArcCatalog, until all available counties had been loaded. U.S. Department of Agriculture. woodmg.dbf - MONROE each soil. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely 2. Soil Surv. Downloadable data is in shapefile format by county. 18. Soil Survey Manual. Consociations - Consociations are named for the dominant soil. U.S. Department of Agriculture. This allows ESRI software to recognize the projection information. Soil Surv. These minor components may be indicated as special features. The actual composition and interpretive purity of the map unit delineations were based on data collected by scientists during the course of preparing the soil maps. components, FOREST.DBF- (forest understory)- stores information for plant cover as forest The COMPONENT.dbf from one county was converted to an SDE table. The following is excerpted from information provided by the U.S.D.A., N.R.C.S. This clause is not intended to restrict distribution of printed mapped information produced from the digital data. 18. For related NJDEP processing, refer to NJDEP Production Processing in the Data Quality Section of this file. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. Any reproduction or manipulation of the above data must ensure that the coordinate reference system remains intact. Agric. Once the extra items were dropped, the MAPUNIT.lut was joined to the coverage .pat of each county using the JOINITEM command with MUKEY as the JOIN field. The database contains both estimated and measured data on the physical and chemical soil properties and soil interpretations for engineering, water management, recreation, agronomic, woodland, range, and wildlife uses of the soil. These standards are outlined in Agricultural Handbook 18, Soil Survey Manual, 1993, USDA, SCS; Agricultural Handbook 436, Soil Taxonomy, Soil Survey Staff, 1975, USDA, SCS; and all Amendments; Keys to Soil Taxonomy, Soil Survey Staff, (current issue); National Soil Survey Handbook, title 430-VI, (current issue). If they have a minimal effect on use and management, or could not be precisely located, they may not be indicated on the map. For more information regarding scale and accuracy, see our webpage at: . NJDEP projected NRCS data to New Jersey State Plane Feet, NAD83. This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. (for example: If Head of Tides filename is HOT.shp, please rename .prj to HOT.prj).
