Topics
  • How the GDW Supports the FSA Geospatial Enterprise
  • Current GDW Environment/Operations
  • Supporting FSA Centralization Efforts
    • NAIP Data Management Changes
    • CLU Replication to the GDW
how the gdw supports fsa farm programs
How the GDW Supports FSA Farm Programs
  • NAIP web services:
    • Provide the ortho base for maintaining CLU boundaries and farm records
    • Provide an intuitive base map for interacting with customers in the county offices
    • Provides a means for identifying current crop growing conditions
    • Assist with disaster assessment
  • Supporting FSA’s efforts with centralizing the CLU dataset
  • Development of CLU topological and attribute based data integrity checks
what the gdw provides
What the GDW Provides:
  • Web services and light weight web applications providing access to national MDOQ and NAIP imagery for county offices and the public
  • Hosting services for a national CLU layer via replication of the CLU from the field service centers
  • Support for APFO NAIP Quality Assurance process via web services
  • Internal APFO web mapping applications (Flight Planning, NAIP Film Search, NRI Status, etc)
gdw data resources integrate with usda geospatial infrastructure

current operations
Current Operations
  • FSA’s geospatial activities are primarily county based
    • CLU managed locally in ArcSDE
    • NAIP CCM primary source of imagery
    • Desktop based applications
  • GDW NAIP web services are also utilized extensively by the county office staff within Desktop environment
  • NAIP web services are UTM based
  • ArcSDE and ArcIMS application architecture for both raster and vector datasets with the GDW
role of gdw within fsa
Role of GDW within FSA
  • Role is not to develop enterprise GIS applications for FSA
  • FSA GIS Office is tasked with GIS application development and Enterprise GIS Architecture definition
  • Responsible for providing hosting services and associated data maintenance for NAIP and CLU datasets
  • Deployment of web services and related web based mapping applications for gaining access to those web services
role of gdw within fsa9
Role of GDW within FSA
  • GDW has been “aligned” with FSA GIS requirements but not necessarily “integrated” within the FSA GIS Enterprise
  • Have been working closely with FSA GIS Office on CLU Replication effort
  • Server architecture is at EOM/EOL
fsa centralization
FSA Centralization
  • FSA GIS Office has been engaging APFO as a fundamental participant in the centralization efforts
  • The GDW is becoming “integrated” into the FSA Geospatial Enterprise
  • NAIP must continue to be provided to the new FSA application environment
  • “Cleaner” CLU is needed for FSA Enterprise/eGov applications such as Customer Statement
aligning gdw with fsa business needs
Aligning GDW with FSA Business Needs
  • State based web services instead of UTM based
  • Multiple years of imagery available
  • Leverage 4-Band data (CIR and NC services)
  • Utilize Image Server and ArcGIS Server
  • Move away from our large (14TB) ArcSDE raster environment
  • Work with GIS Office to integrate NAIP web services into new application architecture
  • Utilize IS and GS within GDW for QA purposes
slide12
Demo
  • NAIP web services
    • Image Server based
    • Multi year data (Indiana)
    • 4-Band sample (Arizona 2007)
  • Using Image Server and ArcGIS Server for QA of GDW data management processes
clu replication to gdw
CLU Replication to GDW
  • Concept is to replicate CLU edits on a weekly basis from each of the 2,350 county offices to the GDW for aggregation into UTM based datasets
  • Each county office replicates edits once per week on a given day
  • Current replication model utilizes file transfer mechanisms
  • When FSA moves to ArcSDE 9.2, a more robust geodatabase replication architecture can be implemented
clu replication to gdw14
CLU Replication to GDW
  • Private (eAuth) web services for integration into USDA applications
  • Public facing web services (no attributes)
clu replication pilot
CLU Replication Pilot
  • Pilot of 21 counties occurring before end of December
  • Pilot to run for 3 weeks
  • National Deployment if pilot is successful
clu value added services
CLU Value Added Services
  • Topological Analysis
    • County based CLU data is merged in UTM extents
    • Perform topological analysis of CLU line work along adjacent county boundaries to detect overlaps, etc
    • Perform same checks for “out of county polygons”
    • Catalog errors inside a data mart and pass datasets to KC for inclusion into web based reporting application
    • State and county personnel review reports and make required CLU updates
    • Over time topological issues between counties are reduced
clu value added services18
CLU Value Added Services
  • Feature and Attribute Reconciliation
    • Compare CLU data ingested in the GDW to the peer tabular data in the Farm Records database located in KC
    • Eliminate “dead” features in each data source
    • Reconcile attribute values (calc-acres) between geospatial layer and the tabular database
    • Catalog errors inside a data mart and pass datasets to KC for inclusion into web based reporting application
    • FSA personnel review reports and make required updates
    • Positions FSA to deploy applications which update both data sets (geospatial and tabular) simultaneously
clu value added services19
CLU Value Added Services
  • Enhanced CLU Delivery via Gateway
    • FSA in some cases merges or splits counties into FSA Locations (AK, PR, CONUS)
    • Example: Nye County, NV – FIPS 32023
      • Split into two “locations” with distinct FIPS Codes
      • 32023 – Northwest Nye, 32035 - Southeast Nye
      • Extracted shapefiles are placed on Gateway and named as per GDMT naming standards
      • Gateway only recognizes valid FIPS 32023 resulting in “Southeast” CLU shapefile not being delivered to customer
    • GDW CLU data management process has built in translation mechanisms to handle all FSA special cases
