Spatial distribution of irrigated areas and their temporal variations are a prerequisite for effective planning, management, and resource conservation. The estimation of irrigated agriculture water-use depends on several factors including crops, cropped acreage, and climatic conditions. Crop types and acreage data are based on the reported information by the producers. The data reporting process might be time-consuming and inconsistent causing delay in producing the required annual water-use summary reports. Moreover, it does not provide the spatial pattern of the irrigated areas for any administrative unit.
