Core Geospatial Data Layers for Soil Survey
Management Areas

• MLRA Region 13

2
Core Geospatial Data Layers

• October, 2007 distribution to all MOs
• Data sets delivered on a 1 Tb hard disk.
• Original distribution included NED, SSURGO, NHD,
  and miscellaneous (TeleAtlas) features
• Distribution in file geodatabase format
• SSURGO was current as of August, 2007
• Elevation derivatives generated
• Data were extracted for SSO areas

Stuff you can and should do with data layers

• Explore relationships in the database
• Use them for developing work plans
• Analyze landscape and landform patterns

layers

• Edit line work
• Worry about topology
• Perform joins between survey areas
