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 Low-lying Areas in Response to Major Flooding: Case Studies in Rockhampton and Bundaberg, Queensland

2021-01-13T11:54:25+11:00April 3rd, 2017|Australia, Earth Observation, Elevation, Flood, Location Intelligence, Major Events, Risk|

3 April 2017 Last Friday we developed two animations that show estimated flood extents of the major floods in Lismore and Murwillumbah, northern NSW. Today we extend that work and apply the same technique to effectively map and visualise many low-lying, flood-prone areas in Queensland. We choose the following two areas for demonstration: Rockhampton [...]

Rapidly Estimating the Flood Extent of Major Floods in Lismore and Murwillumbah on 31 March 2017: Animated Maps Included

Initial release: 31 March 2017 The south-east QLD and northern NSW are often afflicted with widespread flooding caused by the torrential rain typically associated with ex-cyclones, and this time with the remnants of severe Tropical Cyclone Debbie which made landfall on the QLD coast between Bowen and Mackay on 28 March 2017.  Based on [...]

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 systematically [...]

Innovative Earth Observation Image Analysis for Wildfires and Flooding: Two U.S. Examples

2020-10-03T00:50:04+10:00April 1st, 2016|Bushfire, Earth Observation, Flood, Image Analysis, Landsat, Major Events, USA, Wildfire|

Modern Earth Observation satellites are often equipped with special sensors that are capable of measuring the reflectance of ground features at short-wave infrared (SWIR) wavelengths. Most SWIR images currently in use are from the following four major satellites: Sentinel-2 (ESA, 20m resolution for SWIR bands) Landsat-8 and Landsat-7 (NASA & USGS, 30m resolution for SWIR bands) ASTER [...]
