A custom software application was developed to estimate urban landscape water use in a GIS environment using landscape vegetation areas classified from high-resolution airborne multispectral imagery, coupled with ground-based reference evapotranspiration data. Estimates of parcel irrigation water demand were compared with measured volumes obtained by mining urban water billing data. The software tool allows for quick visual identification of high-end users and queries to the spatial database.
