For over 80 years, the Natural Resources Conservation Service has been a pioneer in conservation, working with landowners, local and state governments, and other federal agencies to maintain healthy and productive working landscapes.

On April 27, 1935 Congress establish the Soil Conservation Service (SCS) as a permanent agency in the USDA.

In 1994, Congress changed SCS’s name to the Natural Resources Conservation Service (NRCS) to better reflect the broadened scope of the agency’s concerns.

The creation of the Soil Conservation Service represented the culmination of the efforts of Hugh Hammond Bennett, “father of Soil Conservation” and the first Chief of SCS, to awaken public concern for the problem of soil erosion.

“Soil has long been confused with land. It is but one part of land. For conservation purposes, land must be regarded in terms of all its component parts: soil, slope, climate, susceptibility to depreciation by erosion, over-cropping or other processes of deterioration.”

National Geospatial Center of Excellence (NGCE)

• Support conservation efforts at the field by providing geospatial data, technology, and services

• Provide expertise on GIS/GPS technology, procedure, applications, and tools

• Provide technical geospatial NRCS documents including handbooks, manuals, and technical notes

NGCE (contd.)• Collect hi-res imagery, LiDAR, and

hydrology data and share them as web services as needed

• Provide training and technology transfer on geospatial tools and technologies

• Develop applications/prototypes to meet NRCS objectives and maintain data

Geospatial Data Management • Collect, verify, and maintain natural

resources data

• Provide authoritative data to internal and external customers

• Develop applications to maintain and improve data accuracy

GeoObserver Applications• For Dams – maintain NRCS owned

dams

• For Easements – monitor compliance of easements

• For Elevation – allow internal users to download elevation data and derivatives

14

GeoObserver for Dams• Locate NRCS owned dams by state, county,

and national inventory of dams ID (NIDID)

• Create or update dams with spatial and attribute information

• Export corrected information to US Army Corps of Engineers (USACE)

GeoObserver For Easements• Monitor compliance of long-term & permanent

easements using consistent methods

• Observe selected easements using hi-res imagery from multiple annual collections

• Identify potential compliance issues, remedial procedures, and implementation guidelines

• Report findings to National Headquarters and US Congress as needed

NRCS Data Investment• NRCS helps USDA acquire high quality

elevation data

• Using US Geological Survey (USGS) cost and quality guidelines

• Using National Digital Elevation Program (NDEP) tracker system

Data Investment (contd.)• Collaboration with other state and local

agencies for reduced costs per sq. mile

• Elevation Data collected by fiscal years:– LiDAR – IfSAR– Other resolutions as needed

• Data shared with internal and external users

GeoObserver for Elevation• Share elevation data among internal users across

the nation

• Allow users a choice of datasets, derivatives, and projection

• Provide AOI selection by user sketch, Hydrologic Unit Codes (HUC), USDA Common Land Unit (CLU), and shapefile options

Benefits of GeoObserver applications• Uniform data collection and update

procedures

• Instant access to the best available data from a centrally located enterprise storage

• Uniform reporting procedures

Benefits (contd.)

• Travel costs minimized for the agency

• Increased transparency, high visibility, and availability of data

• Time and cost savings for the agency and taxpayers

Benefits (contd.)• Simple data collection and editing easily

accomplished

• Minimum skill and training for non-GIS users

• ArcMap licenses and training not required

• Hi-res imagery and high quality elevation data already in the application

Technologies used:

• ArcGIS server, SQL Server Spatial, and SDE

• ESRI Silverlight API – Easements and Dams

• ESRI JavaScript API – Elevation

• Visual Studio.NET (C#) 2009 – 2013

Future Steps• Implement similar techniques for other

data layers and projections

• Use lessons learned to improve efficiency

• Adopt mobile technologies wherever possible
