- Description: The Australian Geomechanics Society's (AGS) guidelines on Landslide Risk Management emphasise landslide zonation as a key requirement for regulators dealing with landslide risk (AGS 2007a). The basis for zonation is a landslide inventory which reflects the nature and spatial distribution of landslide types in a particular locale, such as a local government area. This paper describes the design and implementation of a web-based landslide database for south west Victoria aimed at disseminating landslide inventory information to regulators. consultants and the general public. Although the 4,581 mapped landslides represent the most complete and extensive data set for the region, the current data quality and resolution does not meet the AGS guideline for landslide zonation at the municipal planning scale. However, with an essential need for landslide planning controls in this region, the data is the best available for the construction of zonat ion maps, resulting in conservative boundaries at the required map scale. The paper highlights the ongoing need to improve the spatial extent and quality of the landslide database if the statutory planning zonation maps are ultimately to comply with the AGS guidelines.

- Description: Detailed soil data has been collected in the Corangamite region of south-east Australia for over 80 years, as a testament to the productive value of the region’s agricultural soils. Soil science over that period has resulted in soil maps, soil investigation sites and archival materials that provide valuable baseline data for the analysis of trends over time. This legacy data has been brought together with contemporary data in the award-winning Soil Health Knowledge Base, an Internet portal based on spatial data infrastructure that interoperably federates data (open data, research data, industry data, sensor data, legacy data, crowdsourced data … any available data). The portal provides the best available data sources for research and consulting, as well as functions for both the private reward and the public good. The ultimate intent is to provide timely decision support for agricultural enterprises and catchment managers to protect, enhance and restore soil health.
