One of the most innovative features of SkyHarvester is the assessment of rainwater harvesting as a national water resource. Using a generalized linear model (GLM)  to predict rooftop area at the county level (developed with rooftop area from 40 counties) and daily demand data from the United States Geological Survey (USGS), SkyHarvester can provide an estimation  of how much of a county's water supply can be satisfied through RWH. One example of this analysis is shown in the figure below (the example does not considering recycling).
