Remote Sensing Cool Roofs

Various mesoscale climate modeling studies have simulated the climate effects of hypothetical increases in urban albedo.

Remote sensing cool roofs.

Ask question asked 8 years 4 months ago. Blue green red and near infrared. 2012 found that use of cool roofs in chicago for reducing urban heat islands has increased city wide albedo and decreased roof surface temperatures as detected by the landsat satellite. Evaluating chicago s urban heat island policy with remote sensing chris mackey yale university ron smith yale university and xuhui lee yale university since the great chicago heat wave of 1995 the city government has enacted a large number of policies under the pretense that it is combating its urban heat island.

Cool roof in the metropolitan area of mendoza argentina article pdf available in iop conference series earth and environmental science 503. This study utilized high spatial resolution oblique remote sensing data to assess the condition of garage doors and roof. Remote sensing and gis have been widely used in urban environmental analysis. Active 8 years 1 month ago.

Thus this study aimed to develop the roofing layer in order to assess the potential area for rooftop rainwater harvesting adoption by integrating remote sensing and gis approach. A remote sensing study mackey et al. Considering the total amount of asbestos areas validation showed a correct detection of about 80. This paper describes the use of airborne hyperspectral remote sensing for mapping asbestos roofs in an orographic complex area in northern italy the aosta valley.

Using remote sensing to quantify albedo of roofs in seven california cities part 2. Viewed 7k times 30. To derive the albedo of roofs in each city we first locate roof pixels within gis building outlines. Albedo quantification using remote sensing techniques.

With envi image processing and classification tools you can get roofs from images with some spectral value and then you can convert it some vector data for your app. The radiometrically calibrated remotely sensed imagery has high spatial resolution 1 m and four narrow less than 0 1 μm wide band reflectances. Ban weiss ga woods j millstein d levinson r submitted. Remote sensing of the urban heat island effect across biomes in the continental usa marc imhoff nasa earth resource technology et al we find that ecological context significantly influences the amplitude of summer daytime uhi urban rural temperature difference the largest 8 c average observed for cities built in biomes dominated by temperate broadleaf and mixed forest.

Garage doors or roll up doors on residential and commercial structures are vulnerable components that are often damaged in windstorms. Failures of these large openings can lead to internal pressurization which can cause additional structural damage to roofs and walls. Results and application to climate modeling.
