Abstract
Applying High Resolution Imagery / GIS Analysis for Urban Water Conservation
Track: Agriculture
Author(s): John Swindell, Nancy Thomas
As human populations increase, demands on the Earth's natural resources also increase. In many of the arid regions of the United States, water supplies represent a volatile and finite resource. A major consumer of water resources in some areas, especially California, is landscape irrigation. Accordingly, the ability to measure and monitor water usage, especially for irrigation, is a priority. The East Bay Municipal Utilities District (EBMUD) contracted Space Imaging to provide digital multi-spectral 3 foot imagery and image analysis to aid in monitoring irrigation water. A classified land cover map was created that helps the District to accurately measure the landscaped area of customer accounts. This information is used to calculate evapotranspiration for use in the District's water budgets. This paper will review the unique approaches used for applying high resolution image analysis and GIS modeling techniques for satisfying the information requirements of water monitoring in California. A review of techniques, technical problems, and solutions will be provided
