Channels and drains in the Macalister Irrigation District

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from the VicMap Hydro database. The parent dataset(s) is identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.\n\n\n\nSubset of drains and channels contained within the MID. Data derived from the Vicmap Hydro (HY-Watercourse) and contains line features delineating hydrological features. Includes; channels and drains only. Attributed for name. Arcs run downstream. This description is a subset of the metadata available on data.vic.gov.au\n\n## **Purpose** \n\nVicmap Hydro provides an accurate representation of natural and man made Hydrographic features across Victoria, at a capture scale of 1:25,000. It is used in a variety of applications, particularly in emergency services, natural resource management, planning and development, and digital map publication. This dataset includes all drains and channels in the Gippsland Project area, however its principal use was to identify the drains and channels in the Macalister Irrigation district.\n\n## **Dataset History** \n\nThe drains and channels were selected from the Vicmap Hydro dataset (158f64d6-26cf-458b-80f4-f27161be2c55) using the Gippsland Project Boundary ( 27413de5-d13a-4231-ac79-fc77f4cbb5f7 ) to clip the area and then Select by Attribute process in Arcmap to select drains and channels specifically. This selection was saved as a separate dataset. \n\n\n\nThe original line work and points were generated from the Vicmap Digital Topographic (VDT) map base coordinated by LIG. VDT evolved from Victoria's printed 1:25,000 Topographic Map Series program together with the need to supply a control framework for the creation of the rural Digital Cadastral Mapbase. The capture scale is 1:25,000 Statewide and the coverage, except for minor border issues is also statewide.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (XXXX) Channels and drains in the Macalister Irrigation District.
