3 June 2019 We keep demonstrating the potential use of new national contour web maps that have been developed in a recent flood risk analytics project (link). Previous blogs in this series include: Applications of New National Contour Web Maps: Part 1 (Enhancing High-resolution Imagery Mapping) - link In this blog we [...]
30 May 2019 In the previous blog, we reported a national flood risk analytics project that has produced a set of high-resolution tiled web maps on elevation contextual layers and terrain metrics, including contours, modelled surface water flow directions and shaded relief. These web maps are also complementary to desktop, web or mobile [...]
Initial release: 22 May 2019 Over the past few years we have been active developing site-level flood risk analytics tools, e.g. - Introducing Three New Tools for Investigating Flood-prone Areas (link, 11/2017) - Advancing Flood Risk Analytics with Location Profile APIs (link, 09/2018) Now we are pleased to release two additional new [...]
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. [...]
28 January 2019 Over the past few years we have been building cloud-based big data and analytics platforms and foundational Location Profile APIs for property location and hazard risk information. These advances have enabled us to speed up the pace of new product development. Now we are pleased to release a new web [...]
25 September 2018 For flood risk assessment, one may develop flood hazard maps directly or just use existing maps which are often associated with modelled hazard return periods. The quality of each flood map is up to a range of factors, such as the quality of elevation and rainfall inputs, modelling methods, and [...]
21 September 2018 Super Typhoon Mangkhut made landfall in Guangdong Province, China around 5 PM Sunday (16 September 2018) as a Category 2 hurricane (in Saffir–Simpson hurricane wind scale). This blog summarises a number of rapid analyses we performed and some of our existing information products that can be used to help assess the [...]
21 September 2018 Hurricane Florence made landfall near Wrightsville Beach, North Carolina at 7:15 AM on Friday (14 September 2018) as a Category 1 hurricane. This blog summarises some of our existing information products and new analytics that can be used to help assess the impact of this major event. 1. Location [...]
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 [...]
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 [...]
