  • Digital image analysis for mapping the nests integrates Spectral and Visual analysis
  • Phragmites Map: We are collaborating with spatial analyst lab (Michigan Tech Research Institute) using new methods in radar detection of Phragmites. This effort includes, and requires, ground-truthing to ensure accuracy so that resource managers can use the map with confidence.

    In the context of the landscape (PLANET EARTH), how can you manage or restore any feature unless you know:
    Where Is It?
    What Is There?
    How Much Is There?

    Spectral and Visual Analysis
    Cormorant nesting areas are roughly delineated on photo
    A level slice of band 1 was performed to identify the cormorant spectral signature
    The cormorant spectral signature is then converted to polygons….
    And the polygons to points.

  • 43. Focus of Invasive Phragmites Mapping in the coastal Great Lakes
    • 130,672 ha (322,891 acres) freshwater emergent wetlands
    • 44. within 10km coastline
    • 45. Coastal region emergent wetlands most vulnerable to Phragmites invasion
    • 46. water level changes
    • 47. Typha-dominated
    • 48. wet meadow
    • 775 unique field site visits.
    • 49. 459 validation, 316 training
    • 50. Phragmites observed at 29% of sites. (228 of the 775).
    • 51.  14% Validation sites
    • 52. 15% training sites
    • 53. Only NWI "Palustrine Emergent" polygons used to generate random points for validation sites of these, only 53% were documented as emergent in the field observations

  • 63. MERLIN Radar Coverage
    MERLIN's dual, wide-beam radar configuration provides the most complete & cost-effective surveillance
    • Superior coverage to pencil beam
    & parabolic dish radars
    • The horizontal S-band provides
    bird detection even in weather
    3-6 nm diameter
    Vertical radar end view
    Horizontal scanning radar provides bird detection out to 2-4 nm & up to 10,000 feet 360° around the windfarm site
    Vertical radar side view
    Vertical scanning radar provides bird detection out to 1-3 nm & up to 10,000 along wind turbine rows
    10,000 ft AGL
    2-3 nm
  • 64. “Due, in part, to their limited capacity for adaptation, wetlands are considered to be among the ecosystems most vulnerable to climate change.”
    Climate Change and Water
    IPCC June 2008
  • 65. So why is Radar so important?
    Daily coverage in 5 years regardless of clouds
    We could map wetlands over all of North America in a week!
    Radar sees of water containing features

  • 74. CONCLUSION:
    One needs ASSESSMENT Before targeted restoration in order to PREVENT future and more expensive restorations.
  • 75. GOOGLE OMB Place-based
  • 76. ACTION ITEM
    Contact your local, state, tribal and federal government leaders to support and maintain geospatial assessment!
    Why? To PREVENT or minimize cleanup (restoration) of larger future disasters = lower taxes!
