    NAIP and TNRIS NAIP and TNRIS Presentation Transcript

    • A Creative NAIP Buy UP:
      The Texas Experience
      James Scott III
      Texas Natural Resources Information System
      Tim Crago
      North West Geomatics Ltd.
    • Program Summary
      • State of Texas wide coverage (275K sq miles, 254 Counties)
      • 1 meter NAIP deliverable
      • 0.5 meter TNRIS deliverable
      • Single acquisition at 0.75 meter resolution using ADS40 ‘highres’ mode.
      • Multiple product deliveries
      • Summer 2008, winter 2009 seasons
    • Program Chronology
      • North West awarded NAIP contract for Texas in March 2008
      • TNRIS began the process of consolidating partners in June 07 and close involvement with FSA
      • 4 State agencies involved
      • 2008 Acquisition – April 28 – Oct 28
      • 2009 Acquisition – Jan 15 – Feb 28
    • Texas Partners
      Commission on State Emergency Communications (24 regional centers)
      Texas Commission on Environmental Quality (air quality and facilities)
      Texas General Land Office (Coastal Programs)
      Texas Water Development Board (Texas Natural Resources Information System – Strategic Mapping Program and National Flood Insurance Mapping)
      USDA Natural Resources Conservation Service
      U.S. Geological Survey
    • Contract Vehicle - Then
      • TXMAS (Texas Multiple Award Schedule) used by TNRIS to issue buy up contract to North West
      • TXMAS uses the Federal GSA contract obtained by competitive tender as the underlying contract to award a schedule of 50 products and services
      • Buy up award must happen quickly before NAIP acquisition begins
    • Contract Vehicle – Now & Future
      • High Priority Imagery and Data Sets (HPIDS)
      • Authority given to TNRIS to manage statewide GIS data procurement
      • Pool of 21 Pre-qualified data and service providers
    • Project Area Map
      Flight Blocks
      Summer 2008
      Winter 2009
    • The Leica ADS Sensor
      Leica ADS Sensor
      ADS Band Configuration
    • Program Design
      • Original NAIP design was for 1m. resolution imagery; with the State of Texas wanting 50cm.
      • Original 1m. design involved 61,000 line miles of collection.
      • Re-designed for 75cm collection with 83,000 line miles; 36% increase.
      • Altitude change from 30,000’ to 23,000’
    • Technical Approach
      • Leica ADS40-SH52
      • 23,000’ altitude
      • High-res mode acquisition resulting in 0.75m x 0.33m multispectral pixel
      0.375m x 0.165m pan pixel
      • Re-sampled to 1m x 1m for NAIP
      • Re-sampled to 0.5m x 0.5m for TNRIS
      • All products to NAIP specs (with some exceptions)
    • Acquisition Approach
      • With our partners
      • Fugro Horizons – FugroEarthdata
      • Up to 5 Cessna Conquests
      • Equipped with Leica ADS40-SH52
    • Project Quantities
      * - includes overlap between areas
    • Deliverables Discussion
    • Ortho Comparison – 1m
    • Ortho Comparison – 50cm
    • Lessons - General
      • Very short time frame between the NAIP award and the NAIP flying season to negotiate buy-up
      • Essential that State partners/funding in place prior to NAIP award
      • A single strong State entity leader
      • Contract vehicle/mechanism needs to be clear/expeditious; sole sourcing or others
    • Lessons - State
      • State benefits from strong contribution ability (1/3)
      • Importance of strong FSA state office /State Mapping Center relationships
      • Value of positive history of data collaboration across state agencies
    • Summary
      • USDA NAIP deliverables and time lines met
      • TNRIS and the State received 50cm state wide coverage
      • NAIP program funding augmented by State agencies to enhance deliverables to meet the State requirements
