RT Journal Article SR Electronic T1 Assessing Urban Forest Canopy Cover Using Airborne or Satellite Imagery JF Arboriculture & Urban Forestry (AUF) FD International Society of Arboriculture SP 334 OP 340 DO 10.48044/jauf.2008.046 VO 34 IS 6 A1 Walton, Jeffrey T.

YR 2008 UL http://auf.isa-arbor.com/content/34/6/334.abstract AB With the availability of many sources of imagery and various digital classification techniques, assessing urban forest canopy cover is readily accessible to most urban forest managers. Understanding the capability and limitations of various types of imagery and classification methods is essential to interpreting canopy cover values. An overview of several remote sensing techniques used to assess urban forest canopy cover is presented. A case study comparing canopy cover percentages for Syracuse, New York, U.S. interprets the multiple values developed using different methods. Most methods produce relatively similar results, but the estimate based on the National Land Cover Database is much lower.
