  • Hybrid hazels in context
  • Desired project output
  • Data acquisition
  • Procedures
  • Accuracy assessment
  • Results
  • Limitations and potential revisions
hybrid hazels the future is nuts
Hybrid Hazels: The Future is Nuts
  • Hybridization trials
  • Current industry and EFB
  • Current state of midwest industry
potential plantation sites
Potential Plantation Sites
  • Currently underutilized land
  • Along regularly driven routes
  • Semi-rural residential or hobby farm
  • Away from road salt zone
  • At least 1/20th acre
procedure outline data
Procedure Outline - Data
  • Download shapefiles of streets, county roads, major roads, and parcels of Hennepin County
  • Clip shapefiles to general AOI
    • PLSS sections containing regularly traveled roads
pre processing
Pre-processing
  • Dissolve desired sections into 1 polygon
  • Begin selecting and exporting features not desired
    • Parcels less than 1.5 acres
    • Roads with a 55, 75, or 150 foot buffer, depending on road size
    • Erase these undesired areas
pre processing continued
Pre-processing continued
  • Convert single polygon shapefile into multi-polygon
    • Delete small polygon fragments
pre processing1
Pre-processing
  • Download 4 band CIR imagery for Hennepin County 2008 from MNGeo (NAIP)
    • Contained information for the small portion of our AOI in Wright County
    • Summer aerial photographs
    • One meter spatial resolution
classification
Classification
  • Open in ERDAS to run supervised classification
  • Classes:
    • Grass
    • Unused pasture
    • Agriculture
    • Developed
    • Open water
    • Forest
accuracy assessment
Accuracy Assessment

60% overall Accuracy with Grass and Unused Pasture as individual classes

accuracy assessment continued
Accuracy Assessment Continued

70% Overall Accuracy with Unused Pasture and Grass as a combined class

results
Results
  • Total classified acres of suitable land:
    • 1383 grass
    • 1983 unused pasture
limitations possible improvements
Limitations / Possible Improvements
  • Classification
    • Use spring/fall imagery for certain classes
    • More training sites
    • Better definition of desired classes
  • Area of interest filtering
    • Split grass/unused pasture polygons along parcel lines and remove those patches less than 1/20th acre in a single parcel
