Reducing Uncertainties in Catastrophe Loss Modelling: New Advances

December 12th, 2018|APIs, Asia, Australia, Bushfire, Earth Observation, Exposure, Geospatial Big Data Analytics, Hurricane, Insurance, Location Intelligence, Property Information, Risk, Tropical Cyclone, USA|

12 December 2018 This is our 2018 end-of-year review article. Catastrophe loss modelling, as a special type of environmental modelling, has been around for three decades. It captures all essential components of the classic risk equation, i.e. Risk = f (Hazard, Exposure, Vulnerability), and quantifies the likely economic or insured losses [...]

16 April 2018 This brief 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’ [...]

The March 2018 Bushfire in Tathra, NSW, Australia

March 27th, 2018|Australia, Bushfire, Earth Observation, Emergency, Image Analysis, Insurance, Location Intelligence, Major Events, Risk|

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 developed and contributed three information products in response to the disaster in Tathra, a picturesque town at [...]

Progress in 2017: Advancing Emergency and Insurance Applications Using Geospatial Big Data Analytics and Global Earth Observation

December 15th, 2017|Asia, Australia, Earth Observation, Emergency, Geospatial Big Data Analytics, Insurance, Location Intelligence, Risk|

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 and Global Earth Observation. Location intelligence is becoming ubiquitous and increasingly important for a wide range of applications, including emergency [...]

A Survey and Clarification of DEM Vertical Accuracy

December 8th, 2017|Earth Observation, Elevation, Flood, Location Intelligence, Risk, USA|

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 [...]

Visualising Potential Bushfire Risk for Addresses in Australia: A New Cloud-based Approach

October 25th, 2017|Australia, Bushfire, Earth Observation, Location Intelligence, News Media, Property Information, Risk|

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 [...]
