Visualising time-series data with the Australian Hydrological Geospatial Fabric (Geofabric) and the Geofabric Sample Toolbox Darren G Smith1 (Presenter), Mark Menzel2, Matthew Brooks3 1, 2, 3 Australian Bureau of Meteorology, Information Systems & Services Division (Environmental Information Management) , The Geofabric is a digital database of surface and groundwater features providing a spatial framework for water information in Australia. Designed for use with geographic information system (GIS) software, the Geofabric product suite registers the spatial relationships between important hydrologic features such as rivers, water bodies, monitoring points and catchments at scales suitable for national reporting. Geofabric products can be used to perform geospatial analysis of the flow of water throughout the nation and to represent surface and ground water on maps used for forecasting and reporting. In order to support and further promote the use of the Geofabric product suite, the Bureau of Meteorology has put together a set of sample ArcGIS Python script tools that provide examples of how the Geofabric datasets can be used and extended. The toolset supports a number of common workflows performed by hydrologists, such as the creation of a set of custom catchments and node link networks for a given set of monitoring points. The use of the toolset together with the Geofabric removes the need to process DEM data when creating a set of custom catchments. Version 1.6 of the toolset includes new tooling that facilitates the bulk download of monitoring point time-series data from the Bureau's Water Data Online (WDO) portal in a format that is packaged and ready for use with the Geofabric. The presentation will run through an example workflow which, from a starting point of a collection of monitoring points, sees the generation of a node-link network and a set of custom catchments. These custom features are then used to visualise stream height data for a past flood event downloaded from the WDO portal. Reference List Australian Bureau of Meteorology. (2011).
