Method and system for controlling irrigation using computed evapotranspiration values
A system for providing irrigation control is provided. The system includes a number of non-local data sources for providing data, a processor and an irrigation system. The processor is configured to receive data from one or more of the non-local data sources and calculate an evapotranspiration (ET) value for an irrigation area that is non-local with respect to the non-local data sources. The irrigation system is located in the irrigation area and configured to receive the ET value from the processor and provide appropriate irrigation control for the irrigation area using the ET value.
