<p>The dataset is low resolution mapping of irrigated land use in 2024 across the Lower Murray-Darling (LMD), including the Edward/Kolety and Wakool river system. It is derived from high resolution mapping, owned and maintained by SunRISE Mapping & Research, that was used to prepare mapping and report outputs for MDBA contract MD005619. This low resolution version of the mapping was derived by aggregating adjacent areas of the same crop type. The aggregated mapping includes adjacent, non-irrigated areas, hence area figures DO NOT represent accurate irrigated areas and DO NOT compare with those of the high resolution source mapping</p>

The purpose of the dataset is to provide a low resolution version of the mapping
for public access, as per project services of MD005619. No estimate or claim is
made regarding the dataset’s fitness for purpose.

dataset
20250529
The dataset is a low resolution version of high resolution mapping owned and
maintained by SunRISE Mapping & Research. This low resolution version was
derived by aggregating adjacent areas of the same crop type. Large areas such as
almond plantings, were aggregated across divides of up to 200 metres, smaller
areas were aggregated across divides up to 50 metres. The aggregated mapping
includes adjacent, non-irrigated areas; hence area figures do not accurately
represent irrigated areas.
After aggregation, all areas less than 1 hectare were removed from the mapping,
and all ‘vacant’ areas less than 4 hectares were removed from the mapping.
Further information on the source dataset is outlined in the report: SunRISE
Mapping & Research, June 2025, Irrigated crop area data for the Lower MurrayDarling 2003 to 2024, including analysis of the Edward/Kolety and Wakool river
system. Data quality
test and result
Attribute
accuracy
• CROP type for permanent plantings has high reliability (~95%)
• CROP type for seasonal crops (vegetables and field crops) has low reliability
(~65%), as it can be difficult to assess irrigation activity each season
• Area figures are aggregated areas including adjacent non-irrigated areas and
do not represent accurate irrigated areas.
Spatial
Completeness
The dataset is spatially complete, intended to include all irrigated areas over one
hectare in the study region. The study region is described in the report; Irrigated
crop area data for the Lower Murray-Darling 2003 to 2024, including analysis of
the Edward/Kolety and Wakool river system.
Attribute
Completeness
All fields are attributed. Refer to the Data Dictionary below and Table 1 for a
description of attributes.
Positional
Accuracy
No assessment of positional accuracy is made as the mapping contains
aggregated areas i.e. multiple patches of irrigated areas within the one polygon.
Although every effort has been made to ensure the accuracy of the data,
SunRISE Mapping & Research, its agents, officers and employees make no
representations, either express or implied, that the data is accurate or fit for any
purpose and expressly disclaims all liability for loss or damage arising from
reliance upon the data.
