Limitations and potential revisions

3. Hybrid Hazels: The Future is Nuts
Current industry and EFB
Hybridization trials
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
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

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

11. 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

19. 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
