Dataset Identification:
Resource Abstract:
- description: This map and corresponding dataset provide the location, satellite images and square footage of existing green
roofs within the City of Chicago. This dataset is in KML format. To view or use these files, special GIS software such as
Google Earth is required. This information is derived from an analysis of high-spatial resolution (50cm), pan-sharpened, ortho-rectified,
8-band multi-spectral satellite images collected by Digital Globe s Worldview-2 satellite. The City supplied the consultant
with a 2009 City boundary shapefile to determine the required extent of the imagery. Acquisition of three different strips
of imagery corresponding to the satellite s paths was required. These strips of imagery spanned three consecutive months and
were collected in August 2010 (90% coverage), September 2010 (5% coverage) and October 2010 (5% coverage). The results of
the analysis include overall count of vegetated roofs, their total square footage, and the ratio of required to elective vegetated
roofs. A total of 359 vegetated roofs were identified within the City of Chicago. The total square footage of these vegetated
roofs was calculated to be approximately 5,469,463 square feet. The ratio of required vegetated roofs to elective vegetative
roofs was 297:62 (~5:1). The median size of the vegetated roofs was calculated to be 5,234 square feet.; abstract: This map
