Building-level Geocoding of G-NAF (Address Database) for Improved Flood & Bushfire Risk Analysis in Australia

July 1st, 2020|AI, Bushfire, Cloud Computing, Earth Observation, Exposure, Flood, Geocoding, Geospatial Big Data Analytics, Image Analysis, Land parcel, Location Intelligence, Property Information, Risk|

It is well known that exposure location is a major source of uncertainties in either site-level or aggregate risk analysis. Back in 2016, we released a product called Geocoding DoubleCheck (link) to address the location accuracy of parcel-level geocoding. Then we compared the difference between parcel-level and building-level geocoding (Figure 1), and [...]

Some Exposure Analyses in Relation to the Flooding in West & North-West Queensland

February 11th, 2019|Apps, Asset Management, Australia, Earth Observation, Emergency, Exposure, Flood, Geospatial Big Data Analytics, Image Analysis, Insurance, Location Intelligence, Major Events, Property Information, Risk|

11 February 2019 We have been active in reporting and sharing information about the major flooding in Queensland (link to Twitter posts and mass media mentions, e.g. CNN and The Guardian). This brief blog is specific to the flooding in West and North-West Queensland. First, the big picture. We use NASA’s Terra/MODIS imagery (2019-01-02 vs. [...]

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’ [...]
