Why I love #remotesensing - It’s like art and science at the same time! #Chile
“ASTER satellite image of Escondida Cu-Au-Ag open-pit mine is at an elevation of 3050 meters, and came on stream in 1990. Current capacity is 127,000 tons/day of ore; in 1999 production totaled 827,000 tons of copper, 150,000 ounces of gold and 3.53 million ounces of silver. Primary concentration of the ore is done on-site; the concentrate is then sent to the coast for further processing through a 170 km long, 9 pipe. Escondida is related geologically to three porphyry bodies intruded along the Chilean West Fissure Fault System. A high grade supergene cap overlies primary sulfide ore. The above ASTER satellite image displays SWIR bands 4-6-8 in RGB, and highlights lithologic and alteration differences of surface units. Satellite image acquired on April 23, 2000.”
A #map of U.S. vegetation, compiled by A. W. Kuchler, of the University of Kansas, in 1966. #cartography
This 1:7,500,000-scale map, in the Albers equal area projection, has 119 vegetation classes for needleleaf, broadleaf, and combined broadleaf/needleleaf forests; shrubs; grasslands; and shrub/grasslands combinations; and grassland/forest combinations. Vegetation areas were symbolized using the colors in this style along with, for some classes, overlaid pattern fills
AGU 2011: New Map of Antarctica’s Rock Bed #science #climatechange #geography #nasa
“A new, updated map reveals how the Antarctic continent looks under the ice, detailing each mountain range and valley. Beyond its undeniable beauty, this high-resolution map of Antarctica’s bed topography, dubbed BEDMAP2, will help scientists model how ice sheets and glaciers respond to changes in the environment.
A large international consortium of Antarctic field programs, including NASA IceBridge, contributed information to this updated map of bed elevation and ice thickness for Antarctica and the Southern Ocean. The first version of BEDMAP was completed in 2000. The new version, which was presented on Dec. 5 at the American Geophysical Union’s 2011 Fall Meeting, incorporates seismic and radar data from about 265,000 km of airborne surveys over the ice.
“We are lacking fundamental data on ice thickness and bedrock elevation over large parts of Antarctica, because these areas are hard to reach,” said IceBridge project scientist Michael Studinger. “We’ll continue to fill in critical information gaps on places such as the Recovery Glacier in Coats Land, East Antarctica. This area has long been on the wish list of ice sheet modelers, but it is very far away from all research bases.”
This year, IceBridge’s DC-8 aircraft was able to fly four times over Recovery Glacier from Punta Arenas, Chile. “We have collected a landmark data set that will fill a critical hole in new BEDMAP compilations,” Studinger said.

All: If you live in the United States, please take this survey sponsored by the American Geographic Society. You do not have to like geography to take it :)
Interesting article/blog posting on how organizations are using remote sensing and GIS mapping technologies for socioeconomic issues and natural disasters.
