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. 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. This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a 7.5 minute quadrangle format and include a detailed, field verified inventory of soils and nonsoil areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. A special soil features layer (point and line features) is optional. This layer displays the location of features too small to delineate at the mapping scale, but they are large enough and contrasting enough to significantly influence use and management. 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. SSURGO depicts information about the kinds and distribution of soils on the landscape. The soil map and data used in the SSURGO product were prepared by soil scientists as part of the National Cooperative Soil Survey. Digital versions of hydrography, cultural features, and other associated layers that are not part of the SSURGO data set may be available from the primary organization listed in the Point of Contact. 2002082720051216publication dateCompleteAs needed-122.304879-121.96202943.09075142.767806MANDATORY: Short description of the areal domain of the datasetNational Park Service Theme Category ThesaurusSoils IM InventoryISO 19115 Topic CategoryEnvironmentGeoscientific InformationNonesoil surveysoilsSoil Survey GeographicSSURGOSoil Resources InventorySRINational Park ServiceNPSCrater Lake National ParkCrater LakeCRLACounties and County Equivalents of the States of the United States and the District of Columbia (FIPS Pub 6-3) OregonCrater Lake National ParkCounties and County Equivalents of the States of the United States and the District of Columbia (FIPS Pub 6-3) Jackson County Klamath County Douglas CountyUSGS Topographic Map Names Data BaseHamaker Butte Quadrangle (s4312262)Pumice Desert West Quadrangle (s4312263)Pumice Desert East Quadrangle (s4312264)Welch Butte Quadrangle (s4312157)Thousand Springs Quadrangle (s4212206)Crater Lake West Quadrangle (s4212207)Crater Lake East Quadrangle (s4212208)Pothole Butte Quadrangle (s4212101)Red Blanket Mountain Quadrangle (s4212214)Union Peak Quadrangle (s4212215)Maklaks Crater Quadrangle (s4212216)Sun Pass Quadrangle (s4212109) National Park System Unit Code ThesaurusCRLANRIMPWROKLMN National Park System Unit Name ThesaurusCrater Lake National ParkNatural Resource Inventory and Monitoring Program Pacific West Region NPS Regional OfficeKlamath Network NetworkNoneThe U.S. Department of Agriculture, Natural Resources Conservation Service, should be acknowledged as the data source in products derived from these data.

Some of these requirements include: chains must begin and end at nodes, chains must connect to each other at nodes, chains do not extend through nodes, left and right GT-polygons are defined for each chain element and are consistent throughout, and the chains representing the limits of the file (neatline) are free of gaps. The tests of logical consistency are performed using vendor software. The neatline is generated by connecting the explicitly entered four corners of the digital file. All data outside the enclosed region are ignored and all data crossing these geographically straight lines are clipped at the neatline. Data within a specified tolerance of the neatline are snapped to the neatline. Neatline straightening aligns the digitized edges of the digital data with the generated neatline (i.e., with the longitude/latitude lines in geographic coordinates). All internal polygons are tested for closure with vendor software and are checked on hard copy plots. All data are checked for common soil lines (i.e., adjacent polygons with the same label). Quadrangles are edge matched within the soil survey area and edge locations generally do not deviate from centerline to centerline by more than 0.01 inch. The quadrangles in this survey have not been edge matched to the quadrangles in the Klamath County, Oregon, Southern Part soil survey.A map unit is a collection of areas defined and named the same in terms of their soil and/or nonsoil areas. Each map unit differs in some respect from all others in a survey area and is uniquely identified. Each individual area is a delineation. Each map unit consists of one or more components. Soil scientists identify small areas of soils or miscellaneous (nonsoil) areas that have properties and behavior significantly different than the named soils in the surrounding map unit. These minor components may be indicated as special features. If they have a minimal effect on use and management, or could not be precisely located, they may not be indicated on the map. Specific National Cooperative Soil Survey standards and procedures were used in the classification of soils, design and name of map units, and location of special soil features. 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). 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. Adherence to National Cooperative Soil Survey standards and procedures is based on peer review, quality control, and quality assurance. Quality control is outlined in the memorandum of understanding for the soil survey area and in documents that reside with the Natural Resources Conservation Service state soil scientist. Four kinds of map units are used in soil surveys: consociations, complexes, associations, and undifferentiated groups. Consociations - Consociations are named for the dominant soil. In a consociation, delineated areas are dominated by a single soil taxon and similar soils. At least one half of the pedons in each delineation are of the same soil component so similar to the named soil that major interpretations are not affected significantly. The total amount of dissimilar inclusions of other components in a map unit generally does not exceed about 15 percent if limiting and 25 percent if nonlimiting. A single component of a dissimilar limiting inclusion generally does not exceed 10 percent if very contrasting. Complexes and associations - Complexes and associations are named for two or more dissimilar components with the dominant component listed first. They occur in a regularly repeating pattern. The major components of a complex cannot be mapped separately at a scale of about 1:24,000. The major components of an association can be separated at a scale of about 1:24,000. In each delineation of either a complex or an association, each major component is normally present, though their proportions may vary appreciably from one delineation to another. The total amount of inclusions in a map unit that are dissimilar to any of the major components does not exceed 15 percent if limiting and 25 percent if nonlimiting. A single kind of dissimilar limiting inclusion usually does not exceed 10 percent. 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. Every delineation has at least one of the major components and some may have all of them. The same principles regarding proportion of inclusions apply to undifferentiated groups as to consociations. Minimum documentation consists of three complete soil profile descriptions that are collected for each soil added to the legend, one additional per 3,000 acres mapped; three 10 observation transects for each map unit, one additional 10 point transect per 3,000 acres. A defined standard or level of confidence in the interpretive purity of the map unit delineations is attained by adjusting the kind and intensity of field investigations. 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.MANDATORYU.S. Geological SurveyUnknownmapReston, VirginiaU.S. Geological Survey24000paper20002001publication dateUSGS1source material for field mappingU.S. Geological Survey1994remote sensing imageFt.

Boundaries were verified at closely spaced intervals, and the soils in each delineation were identified by traversing and transecting the landscape. Soil scientists described and sampled the soils, analyzed samples in the laboratory, and statistically analyzed the data. The classification and map unit names were finalized at the final correlation in 2001.USGS12001Map compilation was accomplished by transferring soil delineations, special soil features and map unit labels from the field mapped topographic quadrangles to annotation overlays registered to orthophotos. Materials necessary for digitizing were forwarded to staff at the Natural Resources Conservation Service, Oregon state office. Compilation was performed by soil scientists on staff at the Natural Resources Conservation Service Oregon state office. Quality assurance routines were performed by soil scientists on staff at Major Land Resources Area office for Region 1 Portland, Oregon.USGS1, USGS2, NRCS12001The annotated overlays were raster scanned at 300 dots per inch on an Ideal FSS8300DSP scanner the Natural Resources Conservation Service, Major Land Resources Area of in Portland, Oregon. Four control points corresponding to the four corners of the 7.5 minute quadrangles were used during data collection of area and special features. The processing, raster editing, map neatline development, labeling, edge matching, vector conversion and editing were done in LT4X, Version 4.11. The data were created in North American Datum of 1927. Digital Line Graph, Optional (DLG-3) files were written with export ssurgo_area and export ssurgo_spec options in LT4X, Version 4.11.USGS1, USGS2, NRCS12001The data were imported to ARC/INFO, Version 7.21. ARCEDIT was used to correct node and label mismatches. Soil survey boundaries were manually digitized from digital raster graphs. New DLG-3 files were written. The data were forwarded to the Montana Digitizing Unit in Bozeman, Montana for evaluation and certification for SSURGO.USGS2, NRCS2, USGS32001The DLG DOC and TAB directories were imported to ARC/INFO, Version 7.21 by certification staff at the Montana Digitizing Unit in Bozeman, Montana. ARCEDIT was used to correct a node mismatch. Minor codes were renamed to link spatial data map unit labels to the National Soil Information System data base.NRCS32002The National Soil Information System data base was developed by Natural Resources Conservation Service soil scientists according to national standards.USGS12002The Natural Resources Conservation Service State Soil Scientist or delegate, upon completion of data quality verification, determined that the tabular data should be released for official use. A selected set of map units and components in the soil survey legend was copied to a staging database, and rating values for selected interpretations were generated. The list of selected interpretations is stored in the database table named sainterp.NASIS20040426The Natural Resources Conservation Service State Soil Scientist or delegate verified that the labels on the digitized soil map units link to map units in the tabular database, and certified the joined data sets for release to the Soil Data Warehouse. A system assigned version number and date stamp were added and the data were copied to the data warehouse. The tabular data for the map units and components were extracted from the data warehouse and reformatted into the soil data delivery data model, then stored in the Soil Data Mart. The spatial data were copied to the Soil Data Mart without change.NASIS20040427The Natural Resources Conservation Service State Soil Scientist or delegate, upon completion of data quality verification, determined that the tabular data should be released for official use.

The spatial data's coordinate system was transformed to UTM Zone 10, Northern Hemisphere (NAD 83) using ESRI ArcObjects 8.3 "ConvertFeatureClass" and exported to an ESRI shapefile. NASIS 20060120 The National Park Service, Soil Resources Inventory Program verified the soil survey area with the current administrative NPS park boundary dated April 2006. ESRI ArcGIS 9.1. The Soil.shp table of attributes includes the NUMANE from the corresponding database. GIS acreages where calculated with the NPS Alaska Pac utility and added as an attribute. The component soils survey database reflects the MuKey's of corresponding spatial soil survey area represent by Soil shapefile. NPS20060126Attribute accuracy is tested by manual comparison of the source with hard copy plots and/or symbolized display of the map data on an interactive computer graphic system. Selected attributes that cannot be visually verified on plots or on screen are interactively queried and verified on screen. In addition, the attributes are tested against a master set of valid attributes. All attribute data conform to the attribute codes in the signed classification and correlation document and amendment(s).The accuracy of these digital data is based upon their compilation to base maps that meet National Map Accuracy Standards. The difference in positional accuracy between the soil boundaries and special soil features locations in the field and their digitized map locations is unknown. The locational accuracy of soil delineations on the ground varies with the transition between map units. For example, on long gently sloping landscapes the transition occurs gradually over many feet. Where landscapes change abruptly from steep to level, the transition will be very narrow. Soil delineation boundaries and special soil features generally were digitized within 0.01 inch of their locations on the digitizing source. The digital map elements are edge matched between data sets. The data along each quadrangle edge are matched against the data for the adjacent quadrangle. Edge locations generally do not deviate from centerline to centerline by more than 0.01 inch.VectorUniversal Transverse Mercator100.999600-123.0000000.000000500000.0000000.000000coordinate pair0.0000640.000064metersNorth American Datum of 1983Geodetic Reference System 806378137298.257222Special Soil FeaturesSpecial Soil Features represent soil, nonsoil, or landform features that are too small to be digitized as soil delineations (area features).U.S. Department of Agriculture. 1993.

The map unit symbol uniquely identifies each closed delineation map unit. Each symbol is linked to a map unit name. The map unit symbol is also the key for linking information in the National Soil Information System tables. The map unit symbols are not carried within the modified Digital Line Graph file; however, they are made available in a companion attribute file. The attribute file links the minor codes in the Digital Line Graph files to the map unit symbols. Map Unit Delineations are described by the National Soil Information System database. This attribute database gives the proportionate extent of the component soils and the properties for each soil. 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. The National Soil Information System database contains static metadata. It documents the data structure and includes such information as what tables, columns, indexes, and relationships are defined as well as a variety of attributes of each of these database objects. Attributes include table and column descriptions and detailed domain information. The National Soil Information System database also contains a distribution metadata. It records the criteria used for selecting map units and components for inclusion in the set of distributed data. Special features are described in the feature table. It includes a feature label, feature name, and feature description for each special and ad hoc feature in the survey area.U.S. Department of Agriculture. 1999.
