Presentation Transcript
Soil survey data in the gis
Soil Survey Data in the GIS

  • Soil Survey Geographic (SSURGO) Data Base.

  • STATSGO

  • NATSGO


Ssurgo data in the gis
SSURGO Data in the GIS

  • The most detailed of soil survey data.

  • Scales range from 1:12,000 to 1:63,360.

  • Duplicates the original paper surveys.


Ssurgo data in the gis1
SSURGO Data in the GIS

  • Digitized in vector format.

  • Archived in 7.5-minute quadrangle units.

  • Merged to form complete coverage of survey area.


Ssurgo data in the gis2
SSURGO Data in the GIS

  • Map extent is the survey area, e.g., Whitman Co.

  • SSURGO data set includes:

    • map data

    • attribute data

    • metadata


Ssurgo data in the gis3
SSURGO Data in the GIS

  • SSURGO is linked to a Map Unit Interpretations Record (MUIR) attribute data base.

  • MUIR gives proportionate extent of component soils for each map unit.

  • MUIR contains over 25 physical and chemical properties.


Ssurgo data in the gis4
SSURGO Data in the GIS

  • SSURGO data are in DLG-3 or Arc interchange (.e00) file format.

  • Tabular data are in ASCII or .e00 format.

  • Metadata are ASCII.


Ssurgo data in the gis5
SSURGO Data in the GIS

  • Distributed in a UTM projection.

  • Datum is NAD83.


Statsgo data in the gis
STATSGO Data in the GIS

  • Generalized from SSURGO data.

  • Scale is 1:250,000.

  • Used for broad planning (state, regional, multi-state).

  • Link to Soil Interpretations Record (SIR).


Natsgo data in the gis
NATSGO Data in the GIS

  • NATSGO data base is used primarily for national, regional, and multi-state resource appraisal, planning, and monitoring.


Natsgo data in the gis1
NATSGO Data in the GIS

  • Boundaries are from the major land resource area (MLRA) and land resource regions.

  • The MLRA boundaries were generated from state soil maps. The NATSGO maps are digitized at a scale of 1:7,500,000.
