摘要：This project shows the distribution and accessibility of public green space in the city of Waterville, ME. Green space is important in urban areas because it encourages interaction between residents and nature, builds social ties, enhances spatial network, provides public spaces for recreation, and benefits physical and mental health. The city of Waterville does not have accurate GIS data that shows a complete network of green spaces in the city. A 2004 National Land Cover Database classifies areas with vegetation. Waterville city zoning data classifies the land into functional zones. However, previous to our project, the land cover and zoning data were not well connected. For the purpose of this project, we defined “public” as “institutional districts (INST)” and “resource protection (RP)” zones in Waterville city zoning data and classified vegetation as any area with NDVI values between 0.605 and 0.823. We also conducted a least-cost path analysis to form a network between green parcels. The map is projected in the NAD 1983 UTM Zone19N coordinate system.
