1. Using North Carolina’s High-resolution Imagery to Delineate Geospatial Relationships between Man and Canopy MRGAC September 30, 2011 Frank Obusek, Owner & Manager GeoIterations LLC, Asheville, NC

2. Agenda • Geospatial Relationships of Man and Canopy • Image Resources to map Man & Canopy • NC 2010 Statewide Ortho Imagery • NC 2010 Statewide NAIP Imagery • Mapping Man & Canopy www.GeoIterations.com

3. Geospatial Man • Roads • Buildings • Parking Lots • Shopping Malls • Development • Urban Sprawl • Parcels • Landuse • Impervious Surfaces www.GeoIterations.com

4. Geospatial Canopy • Trees • Understory • Habitat • Wildlife areas • Urban Forests www.GeoIterations.com

5. Relationships between Man & Canopy • Geolocation of Built and Natural Environments • Spatially integrated and coexisting • Encroachments on Canopy • Restrictions on Man • Distribution in urban environments www.GeoIterations.com

6. Effects of Man (development) • Degrading water quality • Reduce rain water infiltration • Reduce ground water recharge • Storm water runoff • Increased flooding • Poor air quality • Urban Heat Islands www.GeoIterations.com

7. Benefits of Canopy (urban forest) • Reduces temperature and saves energy • Removal of air & ground pollutants • Carbon Sequestering – Removing CO2 • Reduce Storm Water Runoff • Reduce Erosion • Protect Water Quality http://www.coloradotrees.org/benefits.htm

8. Benefits of Canopy (urban forest) • Extend the life of pavement • Increase traffic safety • Improve Economic Sustainability • Increase Real Estate Values • Increase Sociological Benefits http://www.coloradotrees.org/benefits.htm

9. Management of Man and Canopy • Attempting to balance M&C • Quantify M&C • Retain Tree Canopy during development • Manage planting efforts in urban areas • Establish green areas • Disaster Preparedness • Improve the quality of life and environment • Understand the geospatial distribution of M&C www.GeoIterations.com

10. Geospatial Imaging of M&C • Delineating the geospatial location and extent of man-made features using imagery • Delineating the geospatial location and extent of tree canopy using imagery www.GeoIterations.com
