Definition

A note about the general assessment of the quality of the data set constituting the item.

MAP 

For cartographic materials, use for recommendations on tests to be performed and information to be reported. Find more information about such tests in the Spatial Data Transfer Standard (FIPS 173).

Subfields

 
‡a Attribute accuracy report   An explanation of the accuracy of the identification of the entities and assignments of values in the data set. Use also to include a description of the tests used to determine data quality.
514     The map layer that displays Special Feature Symbols shows the approximate location of small (less than 2 acres in size) areas of soils... ‡d Quarter quadrangles edited and joined internally and to surrounding quads. All known errors corrected. ‡e The combination of spatial linework layer, Special Feature Symbols layer, and attribute data are considered a complete SSURGO dataset. ‡f The actual on ground transition between the area represented by the Special Feature Symbol and the surrounding soils generally is very narrow with a well defined edge. The center of the feature area was compiled and digitized as a point. The same standards for compilation and digitizing used for line data were applied to the development of the special feature symbols layer.
‡b Attribute accuracy value   An estimate of the accuracy of the identification of the entities and assignments of values in the data set.
514     ‡b Approximately 95%.
‡c Attribute accuracy explanation   A definition of the thematic accuracy measure.
514     ‡b Estimated to be 98.5%. ‡c Village names compared to source map--all match, therefore errors are possible only if source maps are incorrect. ‡d Node-to-line, line-to-area topological relationships maintained. Line and area attributes maintained. GRASS 4.0 program "v. support" checks topological relationships. ‡e All incorporated limits shown on USGS quads were digitized. ‡f The accuracy of this data is based upon the use of the source maps...
‡d Logical consistency report   The fidelity of the relationships in the data set and the tests used. See example for subfield ‡c.
‡e Completeness report   The definitions used, generalizations, omissions, selection criteria and other rules used to derive the data set. See example for subfield ‡c.
‡f Horizontal position accuracy report   The accuracy of the horizontal coordinate measurements and a description of the tests used. Use of subfield ‡f is generally limited to cartographic materials. See example for subfield ‡c.
‡g Horizontal position accuracy value   An estimate of the accuracy of the horizontal coordinate measurements in the data set expressed in (ground) meters. Use of subfield ‡g is generally limited to cartographic materials.
514     Horizontal position accuracy 1-3 meters ‡f Differential GPS ‡g 3 meters ‡h Static tests ‡i Bar test ‡j One foot ‡k Bar check.
‡h Horizontal position accuracy explanation   A definition of the horizontal positional accuracy measure. Use of subfield ‡h is generally limited to cartographic materials. See example for subfield ‡g.
‡i Vertical positional accuracy report   The accuracy of the vertical coordinate measurements and a description of the tests used. Use of subfield ‡i is generally limited to cartographic materials. See example for subfield ‡g.
‡j Vertical positional accuracy value   An estimate of the accuracy of the vertical coordinate measurement in the data set expressed in (ground) meters. Use of subfield ‡j is generally limited to cartographic materials. See example for subfield ‡g.
‡k Vertical positional accuracy explanation   A definition of the vertical positional accuracy measure. Use of subfield ‡k is generally limited to cartographic materials. See example for subfield ‡g.
‡m Cloud cover   An area of a data set obstructed by clouds, expressed as a percentage of the geospatial extent. Use of subfield ‡m is generally limited to cartographic materials.
‡u Uniform Resource Identifier   The Uniform Resource Identifier (URI), for example a URL or URN, provides electronic access data in a standard syntax. Use for automated access to an electronic item using one of the Internet protocols or by resolution of a URN. Repeat subfield if digital object has multiple identifiers (URIs).
 

Substituting hexadecimal notation for diacritics and special characters in Uniform Resource Identifiers. When recording a URI in subfield ‡u, you may enter most of the spacing characters listed below as either characters or their hexidecimal equivalents. Consult the table below.

Note: Do not confuse the spacing characters listed below with their long-valid non-spacing counterparts. Use of the spacing characters will be limited almost exclusively to URLs.

Entry method Name Character Alternative entry (hex value)






Enter as character or hex value
Spacing circumflex/circumflex accent ^ %5E
Spacing underscore/low line 1   _ %5F
Spacing grave/grave accent ` %60
Spacing tilde/tilde ~ %7E
Enter as hex value only vertical bar n/a %7C

1   Because the Spacing Underscore may cause problems with MARC output, users may prefer to continue entering it with the hexidecimal value %5F.


‡z Display note   A note that introduces the data in the field.
514 ‡z Completeness: ‡u [URL].
