Project 2 in GIS 4930 Special Topics in GIS focuses on GIS and Landscape Design/Management. The scenario involves using a GIS to answer questions related to Small Business Environmental Stewardship Assistance Act of 2010 which encourages communities to plant trees in urban neighborhoods in order to revitalize communities. The act requires matching funds to be provided by the city and the City Manager is requesting a study to show some quantitative reasons to fund the program. Specifically, the GIS is being used to classify ground cover in Marin City, California to try to answer three questions: 1) How does the stewardship program currently benefit the city in terms of energy savings. 2) How does the program benefit the city in terms of carbon stored. 3)How can the program help to identify areas within the city that would benefit from planting more trees.
The first step in the process was to reclassifying ortho-images of Marin City into classified raster images that can be used to determine three general types of land cover classifications: Trees, Grasses and Impervious Surfaces. As part of the preperation process the following base map was created showing Marin County and Marin City with the area to be classified:
