panchromatic sensor with 0.41-meter resolution. 41-centimeter spatial resolution represents the finest commercial resolution on the market today, currently making GeoEye-1 the satellite with the sensors to beat when it comes
to high-resolution imagery.
The GeoEye company has announced plans for the launch of the GeoEye-2 satellite in 2012, which would provide 0.25-meter spatial resolution
imagery. See Hands-on Application 11.5: Viewing High-Resolution Satellite Imagery for examples of all of these high-resolution images online.
Chapter Wrapup
Satellite remote sensing is a powerful tool for everything from covert surveillance to land-use and land-cover monitoring. The next chapter delves into a
new set of geospatial satellite tools—the Earth Observing System, a series of
orbital environmental satellites that gather data about global processes on
an ongoing basis. Geospatial Lab Application 15.1 returns to using MultiSpec
and has you doing more with Landsat imagery and the multispectral capabilities of the TM sensor.
