  1. Identifying Potential Plantation Sites for Hybrid Hazelnut Production in a Micro-Cooperative Context Frank Falzone Ross Meyer FR 3262 10.December.2012

  2. Outline • Hybrid hazels in context • Desired project output • Data acquisition • Procedures • Accuracy assessment • Results • Limitations and potential revisions

  3. Hybrid Hazels: The Future is Nuts • Hybridization trials • Current industry and EFB • Current state of midwest industry

  4. 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

  5. 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

  6. Area of interest:Portions of Maple Grove, Corcoran,Rogers, St. Michael, Hanover, MN

  7. 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

  8. Pre-processing continued • Convert single polygon shapefile into multi-polygon • Delete small polygon fragments

  9. 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

  10. Classification • Open in ERDAS to run supervised classification • Classes: • Grass • Unused pasture • Agriculture • Developed • Open water • Forest

  11. Classified Image Sample

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

  13. Accuracy Assessment Continued 70% Overall Accuracy with Unused Pasture and Grass as a combined class

  14. Results • Total classified acres of suitable land: • 1383 grass • 1983 unused pasture

  15. Results

  16. Results

  17. 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
