Monitoring Land Cover Changes at the Bushland-Urban Interface: An Image Analysis Approach

August 11th, 2020|AI, Australia, Bushfire, Climate Change, Cloud Computing, Earth Observation, Emergency, Exposure, Geocoding, Geospatial Big Data Analytics, Image Analysis, Land parcel, Location Intelligence, Property Information, Risk, Sentinel-2|

It has been well observed, modelled and reported that bushfire risk is on the rise under a rapidly warming climate. Earth observation, remote sensing and image analysis are among the most important technologies to manage bushfires nowadays - from disaster prevention to preparedness, from hotspots detection to movement monitoring, from response to [...]

Building-level Geocoding for Regional Flood Risk Analysis: A Case Study in Ipswich, Queensland

August 11th, 2020|AI, Australia, Cloud Computing, Earth Observation, Exposure, Flood, Geocoding, Geospatial Big Data Analytics, Image Analysis, Land parcel, Location Intelligence, Property Information, Risk|

One of our recent blogs discussed the importance of building-level geocoding for flood risk analysis (link). If an exposure is wrongly or insufficiently geocoded, corresponding flood risk could be very different. In some extreme cases, the risk could be more than an order of magnitude different. Figure 1 shows a comparison of [...]

Mapping the Coastal Settlement in Wamberal, NSW: Two Approaches

July 29th, 2020|AI, Australia, Cloud Computing, Earth Observation, Elevation, Exposure, Flood, Geocoding, Geospatial Big Data Analytics, Image Analysis, Land parcel, Location Intelligence, Property Information, Risk|

Quite a few coastal properties in Wamberal (NSW) are at risk of constant coastal erosion. This is again heightened by the threat from two Australian East Coast Lows affecting the NSW coast in recent few weeks. Two independent approaches, together with high-resolution public data sources, can be used to map the coastal [...]

Creating Building Footprints and Terrain Features for Web and Desktop Mapping: With Examples from the NSW Coast

July 21st, 2020|AI, Australia, Cloud Computing, Earth Observation, Elevation, Exposure, Flood, Geocoding, Geospatial Big Data Analytics, Image Analysis, Land parcel, Location Intelligence, Property Information, Risk|

High-resolution digital imagery (satellite, aerial or drone-based) and high-resolution elevation data (typically derived from LiDAR point clouds) are increasingly used in local and regional environmental studies. But it is still challenging to extract high-resolution feature attributes (e.g. building footprints from imagery and terrain metrics from digital elevation models) for deeper geospatial analysis [...]

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 [...]

Extracting Features from High-resolution Imagery: An AI-based Processing Service

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

Artificial Intelligence (AI) methods or techniques have been actively explored and used for a long time, but the last decade has seen a surge of very successful and profound applications thanks to the rapid advances in deep convolutional neural networks, the availability of large and high-quality data sources, easy access to high-performance [...]

New Web App: Mapping Daily Confirmed COVID-19 Cases in NSW by Postcode and LGA

April 11th, 2020|Apps, Australia, Census, Cloud Computing, Emergency, Exposure, Geospatial Big Data Analytics, Location Intelligence, Major Events, Risk|

11 April 2020 Strongly motivated by the recent release of more detailed COVID-19 data by the New South Wales (NSW) Government, we have developed a new web app that maps the daily confirmed COVID-19 cases in Sydney and NSW by Postcode and Local Government Area (LGA). Please note that so far [...]

BigData Earth Develops New Location Profile Report for Worldwide Agricultural Land

December 5th, 2016|Agriculture, Asia, Asset Management, Australia, Climate Change, Cloud Computing, Earth Observation, Flood, Geospatial Big Data Analytics, Image Analysis, Location Intelligence, Property Information, USA|

Modern Earth observation technologies (spaceborne, airborne and terrestrial) are increasingly deployed to capture environmental attributes about agricultural land and assets. Geospatial big data collected by various sensors and the information extracted are critical for the growing AgTech and digital agriculture business. Many baseline terrain and environmental metrics for agricultural land should be [...]
