New Dataset – ABS Socio-Economic Indexes for Areas (SEIFA) – to Enhance Property Location Profile Report

April 18th, 2018|Australia, Census, Exposure, Location Intelligence, Property Information|

18 April 2018 The Australian Bureau of Statistics (ABS) released the long-awaited Socio-Economic Indexes for Areas (SEIFA, based on 2016 Census) dataset on 27 March 2018 (link). SEIFA is a modelled measure by integrating a wide range of social and economic attributes about the Australian population in an geographic area. SEIFA is generally regarded as one [...]

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 [...]

Introducing Three New Tools for Investigating Flood-prone Areas in the U.S. and Australia

November 21st, 2017|Australia, Elevation, Flood, Location Intelligence, Property Information, Risk, USA|

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 [...]

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 [...]

Some Imagery Sources for the Northern California Wildfires in October 2017

October 16th, 2017|Earth Observation, Location Intelligence, Major Events, News Media, USA, Wildfire|

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. [...]

News Release: BigData Earth Offers Cloud-based Rapid LOCATION Analytics For The News Media Worldwide

August 28th, 2017|Asia, Australia, Earth Observation, Location Intelligence, Major Events, News Media, Risk, USA|

28 August 2017 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 [...]
