How do we go from dirt to digits

How do we go from Dirt to Digits?

  • “Laws are like sausages. It’s better not to see them being made.” Otto von Bismark

  • “Any sufficiently advanced technology is indistinguishable from magic.” Arthur C. Clarke


The soil survey geographic database ssurgo

The Soil Survey Geographic DatabaseSSURGO

  • Digitized version of the Soil Survey publications + added value

  • Compiled to orthographic base

  • Photogrammetric distortions removed

  • Scale of 1:12,000 or 1:24,000

  • Standards in National Soil Survey Handbook

  • Rigorous review and certification process

  • Acquire more elevation data wherever possible


Tim prescott s nrcs gis mission statement

Tim Prescott’s NRCS GIS Mission Statement

To develop, acquire and disseminate digital data and technologies that will enhance the processes of sound resource management, policy and planning.


Nrcs responsibilities for geospatial data

NRCS responsibilities for geospatial data:

  • Soils

  • NAPP Digital Orthophotography (in partnership with USGS and FSA)

  • Watershed boundaries

  • National Resource Inventory (NRI)


How can the geospatial community help

How can the geospatial community help?

  • Cooperative agreements

  • Contact legislators and other agencies about the importance of soils data, DOQQs, etc.

  • Share your data

  • Help us research and develop new tools and data
