EDIT La raison [b]officielle [/b]du deploiement : [i]"During the same timeframe, MRP remote sensing specialists collaborated with the U.S. Air Force and NASA personnel on a preliminary airborne hyperspectral survey of selected high-priority regions of Afghanistan. [b]This data, collected from a WB-57 aircraft[/b], is being used to map specific minerals associated with hydrothermal processes that might identify areas of mineral potential."[/i] [url=http://minerals.usgs.gov/performance/2006_accomplishments.html]Source[/url] [i]"To aid the Afghan Reconstruction effort, the Afghan government is funding USGS to collect airborne gravity, magnetic, orthophoto and synthetic aperture radar data from a Navy Research Laboratory (NRL) Orion P3 aircraft and [b]AVIRIS data from a WB57 aircraft in fall 2005[/b]. These data will provide surficial information on faults, mineral assemblages, and reveal the subsurface structure and lithology of Afghanistan that will aid in resource and hazards assessments for the country. USGS, NRL, and Afghan Geological Survey employees will jointly collect, reduce, and analyze the data. The databases will provide a valuable resource for the Afghan Geological Survey"[/i] [url=http://crustal.usgs.gov/projects/cooperative_projects.html]Source[/url] Je lance un sondage...
