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. [...]
8 June 2018 The public release of BigData Earth's Location Profile APIs is a milestone in our vision of achieving API-first, cloud-based big data analytics and innovative solutions. [Update 31 August 2018: APIs Version 2.0 out of beta] The set of APIs released now reflects our substantial R&D in the following major applications over [...]
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 [...]
15 December 2017 Time flies and another year comes to an end. This blog summarises and highlights what we have achieved during 2017. Our vision has been to create innovative location-centric applications using Geospatial Big Data Analytics, Global Earth Observation and Cloud Computing. Location intelligence is becoming ubiquitous and increasingly important for a wide range of [...]
8 December 2017 For flood hazard modelling and risk analysis, Digital Elevation Model (DEM) is indispensable. Probably the most important metric about DEM quality is its vertical accuracy. Unfortunately, it is often confusing in literature and among various data offerings, and there are serious implications for applications, e.g. whether flood hazard rating can be confidently quantified [...]
21 November 2017 Flood mapping for large areas (e.g. from catchments to a national level) is relatively new and challenging; associating mapped flood-prone areas with an annual chance of occurrence (in probabilities, say 1%) of a flood event involves many kinds of uncertainties and is even harder. Flood maps that suggest various hazard levels over [...]
25 October 2017 It's well known that hundreds of thousands of Australian properties (e.g. residential, commercial and industrial) at the urban-bushland interface are very prone to damaging bushfires. Increasing population, urban encroachment into bushland and a dangerous warming climate all suggest that bushfire risk is on the increase. Bushfire risk assessment has been a [...]
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 [...]
