Objectives:

• Develop a remote sensing-based mapping approach for urban forests that can be implemented nationally.

• Operational procedures for deriving percent forest and impervious land cover

Approach:

• High-resolution images train moderate-resolution image classification

• Model building

• Image processing tools
