Methodology

Methods: 

A fine-resolution land-cover mapping methodology to produce a complete study area map was adopted. The methodology used object-based image analysis (OBIA) remote sensing techniques to classify fine-spatial resolution aerial imagery into seven land-cover categories: bare soil, coniferous forest, deciduous forest, fine green grass, impervious surfaces, water, and wetlands. The imagery used in the classification was 0.5 m spatial resolution, 4-band (R,G,B,NIR) aerial photographs taken between 9 and 17 April 2005. Ancillary data included GIS layers of Massachusetts Department of Environmental Protection (DEP) wetlands and impervious surfaces. The aerial photography and ancillary data were obtained from MassGIS.
