Abstract | Substantial advances in Geographic Information Software (GIS) capabilities and improved access to detailed digital elevation models (DEM) produced from LiDAR (Light Detection And Ranging) has improved the quality of waterway mapping which also allows for detailed analysis of waterways over large areas. Studies of waterways over large areas are usually determined from large grid size (20-30 m) DEMs. In this work, a detailed waterway network was created over a 1096 km² area using a 10m DEM. Studies of this type over such a large area are rare because of the lack of suitable raw data and the amount of work and cost required to create and process the data. The motivation for this work came from a requirement of the Ipswich City Council (ICC) for an upgraded stream ordered waterway network to support their vision for healthier waterways within the city (Kavanagh, 2009). The new high quality stream ordered waterway network enables the identification and prioritisation of riparian corridor management activities along waterways and facilitates the monitoring and improvement of water quality. |
