Description: The ICA catchment boundaries were derived from the NSW River Basins spatial layer stored within the Corporate Enterprise Database (EDBP) layer, ADMIN.NSWCatchments\NSWRiverBasins. This dataset was adapted from the Australian River Basins 1997 spatial layer published by Geoscience Australia. (Australian River Basins 1997 was the result of a joint State and Commonwealth project to create a national spatial database of major hydrologic basins used in the assessment of water resources. The data was derived from topographic maps at scales ranging from 1:10 000 to 1:250 000.)Please note that some Irrigated Crop Areas assigned to a catchment may fall outside its mapped boundary. This can occur where properties located near catchment boundaries extract water from rivers within the catchment (e.g. along the Barwon–Darling River), resulting in irrigated areas being associated with the hydrologic catchment despite lying outside its spatial extent.

Name: Irrigated Crop Areas - Barwon Darling Summer
Display Field: Catchment
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: This dataset contains a satellite observed timeseries of the extent of irrigated summer crop areas in NSW from present day, back to 1987. Observations have been derived from medium-resolution multi-spectral satellite imagery (30m/pixel Landsat with a 16 day return interval and 10 m/pixel Sentinel-2 with a 5 day return interval). The presence of irrigated crops is derived from the application of the Normalised Difference Vegetation Index (NDVI), which quantifies vegetation density and health based upon the reflectance of red and near-infrared light in multispectral satellite imagery. Expert opinion is then applied to qualify whether a field was irrigated, based on its greenness relative to the surrounding landscape throughout the summer season (December to April). The polygons are delineated in a semi-supervised manner and are accurate to the closest hectare. It should be noted images captured in December may reflect signs of water application representative of irrigated areas, but on account of limited visA metadata and data quality statement is available in the Documents section of the dataset homepage on the NSW SEED portal.
