Landsat for the 21st Century
Using currently available technology and operational procedures it is possible to build a Landsat system that has significantly better spatial, spectral, and temporal resolution than the current Landsat. The key characteristic of the 21st Century Landsat is that it acquires information rather than data. The system primarily observes land areas that have changed or are changing.
The 21st Century Landsat will maintain Landsat data continuity as well as being a source of near real-time Earth observations. Using off-the-shelf proven technologies and operational procedures that have been demonstrated in many satellite systems, the system will produce information that is of higher quality, greater relevance, and is easier to use. Modern information acquisition, processing, and distribution systems would expedite the availability of information to the users.
The final benefit of the 21st Century Landsat is that it would be significantly more cost-effective than the current Landsat. Design studies have shown that a constellation of 5 satellites would provide the optimum performance at a significantly lower cost than the current single satellite system.
If steps are not taken to update the Landsat system, it is in danger of becoming irrelevant, except as a source of historical data, as newer and better Earth observing systems become available.
