GIS Lounge has a fascinating post that talks of research undertaken at TelAviv University and the University of California, Los Angeles, which has created a method for more precisely pinpointing the geographic origin of a person's ancestry, by developing an understanding of the spatial diversity of genes. LiDAR News has a piece on […]

Satellites reveal unprecedented Greenland melting
Greenland's surface ice cover last month melted over a larger area than ever detected in more than 30 years of satellite observations, NASA has said. According to measurements from three separate satellites analysed by NASA and university scientists, an estimated 97% of the ice sheet surface thawed at some point in mid-July, the […]
Australia creates world’s first continent-scale mineral maps
A new suite of mineral maps will enable mining companies to increase the efficiency and viability of their exploration efforts. The world-first maps were generated from a ten-year archive of raw Advanced Spaceborne Thermal Emission and Reflection (ASTER) data collected by NASA and the Japanese Government’s Japan Space Systems. CSIRO scientists have […]

This week saw the successful (yay!) landing of the latest Mars rover, Curiosity. If you missed the teary live landing, you can catch up on the mission details here. I don’t know about you, but I prefer this kinda thing to the Olympics. In fact, in the midst of all this space fever, […]
Landsat celebrates its 40th anniversary
This week marks the 40th anniversary of the launch of the first Landsat satellite. Landsat 1 was launched on 23 July 1972; at that time the satellite was known as the Earth Resources Technology Satellite (ERTS). It was the first Earth-observing satellite to be launched with the express intent to study and monitor […]
Japanese supply vehicle launches two new earth observation imagers
Two new earth observation camera systems recently launched aboard the Japanese HTV-3 transfer vehicle, headed to the International Space Station. The seven-day trip will end with delivery of the cameras and other supplies on July 27. The cameras will acquire imagery for disaster analysis and environmental studies. The Environmental Research and Visualization System […]
New tool enables weather satellites to ‘see’ through clouds
Scientists from the University of Iowa (UI), in the US, have created a technique to help weather monitoring satellites "see" through the clouds, and better estimate the concentration of pollutants, such as soot. The finding is important, because, like GPS systems, clouds block remote-sensing satellites' ability to detect, and thus calculate, the concentration […]
Topcon partners with UFO investigators for National Geographic Channel
Chris Carter’s famous X-Files slogan,“The truth is out there,” will be put to the test when a team of pioneering investigators pushes the limits to find the truth behind unexplained UFO sightings, using modern technology for data collection and analysis. According to the National Geographic Channel (NGC), these real-life “Scullys and Mulders” are not looking […]
GPS technology improves weather forecasting
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 […]

The ever-interesting O’Reilly Radar has a great piece on the history of data journalism. If you don’t know what it is, it’s worth a look, but even if you do, you should take a look anyway, as the practice is works hand-in-hand with geospatial data. GIS Café has an overview of GeoEye’s public […]
