Researchers at RMIT University's SPACE Research Centre and the Bureau of Meteorology are using GPS and low earth orbit satellites to provide an additional type of temperature profile observation for use in weather forecasting computer models. The computer models draw on about a hundred thousand million current weather observations, including data from 30 […]

Moho discontinuity mapped
The first global high-resolution map of the boundary between Earth’s crust and mantle – the Moho – has been produced based on data from ESA’s GOCE gravity satellite. Understanding the Moho will offer new clues into the dynamics of Earth’s interior. Earth’s crust is the outermost solid shell of our planet. Even though […]
US Government to reduce cost of Landsat
U.S. government agencies are collaborating to figure out ways to reduce the cost of future Landsat missions, as a result of congressional direction included in the 2012 budget. “Although Congress has provided $2 million to the U.S. Geological Service for Landsat 9 program development, they have also requested that the Administration re-examine how […]
GA releases new satellite imagery gallery and digital maps
Geoscience Australia has today released two new bodies of work adding to its range of cartographic information used by decision makers, researchers, industry and the public. The first is a collection of 28 digital maps that will give oceanographers, scientific researchers, resource exploration companies, tourism operators and the public a greater understanding of […]
Quasars help in accurate positioning
Scientists will be able to measure points on Earth much more accurately, following analysis of data that confirms the movement of our solar system in relation to the centre of the Galaxy. Since 1728, after pioneering work by astronomer James Bradley to verify Earth’s passage around the Sun, it has been confirmed that […]

Lidar News links us to an MIT article talking about a new smartphone app that allows quick creation of 3d models, just by snapping a few pics on your phone’s camera. GIS Lounge has an interesting piece on using thermal imagery to view relative heat loss of buildings at night, in order to […]
Australia needs eye in the sky to help with floods, says professor
Australia is in need of an early warning system to increase its ability to manage natural disasters, according to Linlin Ge, associate professor at the University of New South Wales School of Surveying and Spatial Information Systems. Writing in the Melbourne Age, Ge says the current floods in Queensland – where tens of thousands of […]
Mapping the Ocean Floor
JON FAIRALL It’s a truism that the surfaces of Mars and the Moon are better mapped that the surface of the Earth. Three-quarters of our globe is covered by a layer of water several kilometres thick. Mapping through the murk is difficult and expensive. However, the news is not all bad. New technologies are making […]
Cyclone Sidr Devastates Bangladesh
On 15 November 2007, a category 4 cyclone, called Cyclone Sidr, came ashore in Bangladesh. Wind speeds reached 225 km/h; some waves were eight metres high. More than 3200 people died. Bangladesh is a prisoner of its geography. Three rivers, the Brahmaputra, the Ganges and the Meghna, rise in the Himalaya mountains before they converge […]
