Layer Descriptions

surveyareapoly

This layer corresponds to our SSURGO survey area status map polygon feature class (as opposed to our SSURGO survey area boundary polygon feature class). Tabular attributes include survey area symbol (sastatusmap.areasymbol), survey area name (sastatusmap.areaname), survey area publication status code (sastatusmap.sapubstatuscode), survey area publication status name (sastatusmap.sapubstatusname), the date and time when the corresponding record was last updated (sastatusmap.wlupdated), the map region in which the corresponding survey area occurs (sastatusmap.mapregion), manuscript status code (sastatusmap.manustatuscode), manuscript status name (sastatusmap.manustatusname), survey area version number (sastatusmap.saversion), survey area version established date and time (sastatusmap.saverest) and a Boolean value that indicates is data for the corresponding survey area is complete (sastatusmap.iscomplete).

For a GetMap request for this layer, polygon fill is solid. Brown fill indicates that spatial data is available for the corresponding survey area and grey fill indicates that spatial data is not available for the corresponding survey area.

surveyareapolytransparent

This layer corresponds to our SSURGO survey area status map polygon feature class (as opposed to our SSURGO survey area boundary polygon feature class).

For a GetMap request for this layer, polygon fill is 75% transparent. Brown fill indicates that spatial data is available for the corresponding survey area and grey fill indicates that spatial data is not available for the corresponding survey area.

surveyareapolyoutline

This layer corresponds to our SSURGO survey area status map polygon feature class (as opposed to our SSURGO survey area boundary polygon feature class).

For a GetMap request for this layer, there is no polygon fill.

mapunitpoly

This layer corresponds to our SSURGO map unit polygon feature class. Within a survey area for which spatial data is available, this feature class is required. Tabular attributes include survey area symbol (mupolygon.areasymbol), survey area spatial version (mupolygon.spatialversion), map unit symbol (mupolygon.musym) and map unit key (mupolygon.mukey).

mapunitpolyextended

This layer corresponds to our SSURGO map unit polygon feature class. In addition to the tabular attributes included for layer “mapunitpoly”, each aggregated attribute in table “muaggatt” for the corresponding map unit is also returned.

mapunitpolythematic

This layer corresponds to our SSURGO map unit polygon feature class rated for a selected soil property or interpretation. In addition to the tabular attributes included for layer “mapunitpoly”, rating class attributes "MapUnitRatingString" (for character-valued classes), "MapUnitRatingNumeric" (for numeric-valued classes) and "RgbString" (for polygon fill color) are also returned.

mapunitline

This layer corresponds to our SSURGO map unit line feature class. Within a survey area for which spatial data is available, this feature class is optional. Tabular attributes include survey area symbol (muline.areasymbol), survey area spatial version (muline.spatialversion), map unit symbol (muline.musym) and map unit key (muline.mukey).

mapunitlineextended

This layer corresponds to our SSURGO map unit line feature class. In addition to the tabular attributes included for layer “mapunitline”, each aggregated attribute in table “muaggatt” for the corresponding map unit is also returned.

mapunitlinethematic

This layer corresponds to our SSURGO map unit line feature class rated for a selected soil property or interpretation. In addition to the tabular attributes included for layer “mapunitline”, rating class attributes "MapUnitRatingString" (for character-valued classes), "MapUnitRatingNumeric" (for numeric-valued classes) and "RgbString" (for line color) are also returned.

mapunitpoint

This layer corresponds to our SSURGO map unit point feature class. Within a survey area for which spatial data is available, this feature class is optional. Tabular attributes include survey area symbol (mupoint.areasymbol), survey area spatial version (mupoint.spatialversion), map unit symbol (mupoint.musym) and map unit key (mupoint.mukey).

mapunitpointextended

This layer corresponds to our SSURGO map unit point feature class. In addition to the tabular attributes included for layer “mapunitpoint”, each aggregated attribute in table “muaggatt” for the corresponding map unit is also returned.

mapunitpointthematic

This layer corresponds to our SSURGO map unit point feature class rated for a selected soil property or interpretation. In addition to the tabular attributes included for layer “mapunitpoint”, rating class attributes "MapUnitRatingString" (for character-valued classes), "MapUnitRatingNumeric" (for numeric-valued classes) and "RgbString" (for point symbol color) are also returned.

featline

This layer corresponds to our SSURGO feature line class with extra description drawn from the related feature description class. Tabular attributes include survey area symbol (featline.areasymbol), survey area spatial version (featlines.spatialversion), a very short feature symbol (featline.featsym), feature name (featdesc.featname) and feature description (featdesc.featdesc).
