The State of California needs to manage its water wisely. One significant loss to the hydrologic system is landscape irrigation. There are around 9 million single family residences in California most of which have some degree of landscape irrigation demands. California Department of Water Resources (CADWR) working with Quantum Spatial and Eagle Aerial Solutions has developed an approach that allows the mapping of irrigated and irrigable areas in a consistent manner across the state, which when combined with climate data can provide an estimate of required evapotranspiration for that landscape. This estimate provides a fair and equitable assessment of water requirements for individual water districts.
The approach utilized a combination of object based image analysis and innovative statistical techniques to estimate the irrigated and irrigable areas for each parcel across the state. The classification system was developed to capture land management associated with irrigation use. The presentation will cover the approach taken, the critical components of the approach and initial results of the analysis. Although developed for irrigation management the approach can be applied to any classification where land use rather than land cover is required.
