31 August 2018 This blog summarises some of our latest activities of monitoring, modelling and mapping major hazardous events with Earth observation and geospatial big data analytics, the two methods that are increasingly important and indispensable for a wide range of environmental studies. We routinely apply our own advanced image analysis software (Spectral Discovery) [...]
18 June 2018 Almost every industry has some types of exposure data, and its data quality and analysis are crucial for overall exposure management and decision making. For the businesses dealing with environmental, industrial, technological and man-made hazards and risk, the spatial and temporal accuracy of the underlying exposure data is among the most important. [...]
16 April 2018 This blog provides a rapid response to the major bushfires in Sydney’s south-west on the weekend (14-15 April 2018). Unseasonably warm weather (more akin to summer than autumn) caused major bushfires in Sydney’s south-west on Saturday 14 April 2018, posing a serious threat to many properties in nearby suburbs. NSW RFS’ major [...]
27 March 2018 It is quite unusual to have extreme fire weather in autumn in Australia, which has caused widespread bushfires (e.g. fires in SW Victoria and fires in the Alpine National Park) and devastating property damage. We have developed and shared three information products in response to the disaster in Tathra, a picturesque town [...]
12 March 2018 Devastating flooding once again took place in the North Queensland region. The Bureau of Meteorology had issued major flood warnings for quite a few river catchments, including: Herbert River Murray River Tully River Johnstone River Russell River Mulgrave River Among the regional cities and towns affected, Ingham has suffered the most damage as [...]
16 October 2017 The catastrophic wildfires in Northern California started a week ago have claimed at least 40 lives and destroyed nearly 6,000 buildings (news report). The fires continuously burning over the past week and the extensive damage have been observed by low-, medium- and high-resolution satellite imagery. Here we summarise and analyse a few useful imagery sources. [...]
Location information is critical for news reporting, especially in the event of emergencies, natural disasters, industrial pollution, etc. Relevant location information and insights can not only make the news story more detailed and interesting, but also help readers understand each event and its context more quickly. BigData Earth has been developing unique location [...]
26 June 2017 Location information and insights are becoming ubiquitous and more important than ever. Tangible and easy-to-read location information, mainly through maps and various visualisation techniques, enhances our understanding of many dynamic phenomena. For the current news reporting on major hazardous events taking place around the world, there is a need to include more detailed and coherent [...]
3 April 2017 Last Friday we developed two animations that show estimated flood extents of the major floods in Lismore and Murwillumbah, northern NSW. Today we extend that work and apply the same technique to effectively map and visualise many low-lying, flood-prone areas in Queensland. We choose the following two areas for demonstration: Rockhampton [...]
Initial release: 31 March 2017 The south-east QLD and northern NSW are often afflicted with widespread flooding caused by the torrential rain typically associated with ex-cyclones, and this time with the remnants of severe Tropical Cyclone Debbie which made landfall on the QLD coast between Bowen and Mackay on 28 March 2017. Based on [...]
