Layer Descriptions
Although our data includes a State Soil Geographic Database (STATSGO) map unit polygon feature class, this feature class is not available via a Web Map Service (WMS) or Web Feature Service (WFS) web service at this time. Data in the underlying spatial data table (gsmmupolygon) may, however, be accessed via Structured Query Language (SQL) queries.surveyareapoly
This layer corresponds to our Soil Survey Geographic Database (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 Soil Survey Geographic Database (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.

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 Soil Survey Geographic Database (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).
For either WFS or WMS services, if either "aoiid" or "interpresultid" are specified the returned layer data are constrained to the related persistent AOI's area. If "interpresultid" is specified then WFS will also return rating class attributes "MapUnitRatingString" (for character-valued classes), "MapUnitRatingNumeric" (for numeric-valued classes) and "RgbString" (for symbol color). In WMS the map features will be colored according to the "RgbString".

For either WFS or WMS services, if either "aoiid" or "interpresultid" are specified the returned layer data are constrained to the related persistent AOI's area. If "interpresultid" is specified then WFS will also return rating class attributes "MapUnitRatingString" (for character-valued classes), "MapUnitRatingNumeric" (for numeric-valued classes) and "RgbString" (for symbol color). In WMS the map features will be colored according to the "RgbString".
mapunitpolythematic
This layer corresponds to our Soil Survey Geographic Database (SSURGO) map unit

class attributes "MapUnitRatingString" (for character-valued classes),
"MapUnitRatingNumeric" (for numeric-valued classes) and "RgbString" (for polygon

(muline.musym) and map unit key (muline.mukey).
For either WFS or WMS services, if either "aoiid" or "interpresultid" are specified the returned layer data are constrained to the related persistent AOI's area. If "interpresultid" is specified then WFS will also return rating class attributes "MapUnitRatingString" (for character-valued classes), "MapUnitRatingNumeric" (for numeric-valued classes) and "RgbString" (for symbol color).
