11 March 2020 Exactly four years ago, we started blogging what we have been exploring and creating in geospatial big data analytics, cloud computing, property location metrics, hazard and risk modelling, etc. So far, more than 50 blogs have been produced. Here we select and share top 10 blogs from the past [...]
9 December 2019 LiDAR point clouds can represent 3D features very accurately, but due to their large data sizes, point clouds are commonly turned into easy-to-use DEMs at various spatial resolutions (e.g. 1m, 5m or 10m). Such DEMs are increasingly available via government web portals. The vertical accuracy of 1m-resolution Lidar-derived DEMs [...]
9 December 2019 Many of us work with elevation data (e.g. LiDAR point clouds and Digital Elevation Models - DEMs) on a daily basis. Nowadays there are an increasing number of government sources for open elevation data, including high-quality, LiDAR-derived DEMs. As we have recently introduced (link to the previous blog), elevation data [...]
18 September 2019 Google Maps is very popular and easy to use, and many of us would have imagined creating and delivering domain-specific mapping layers in the same or similar way Google Maps does. To realise this, we have recently created and released a set of new, high-resolution tiled web maps (or tile [...]
12 August 2019 Over the past four years we have been undertaking significant new R&D in property location and hazard risk analytics with cloud computing. In particular, we have developed an organic set of products based on three new technologies (Web APIs, Web Apps and Web Maps) to support two cloud-based geospatial [...]
18 June 2019 We keep showcasing the potential application of new high-resolution contour web maps for Australia that have been recently developed (link). Previous blogs in this series include: Applications of New National Contour Web Maps: Part 2 (Identifying Low-lying Coastal Areas) - link Applications of New National Contour Web Maps: Part [...]
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 [...]
22 February 2019 It's good news that tropical cyclone Oma has weakened and remains offshore. Here we perform some quick analysis using the web APIs & Apps recently developed, and share results with the public (see Twitter posts below). 1. Overview of Current Exposure Why are we so concerned about this event? [...]
