From page 53...
... Implication: All data granules distributed by NASA and NOAA should include a digital signature calculated by a standard, open algorithm, so that NASA and NOAA and any subsequent users of the data can verify its integrity.

From page 54...
... Even if the relationship were always one to one, there is a general need to be able to refer to granules with names that make some sense to users, as opposed to the apparently random bit strings of digital signatures. Implication: All data streams distributed by NASA and NOAA should have a well-defined granule naming convention.

From page 55...
... Implication: All NASA and NOAA satellite data should be accessible via standard Web services. Data usability cuts directly to the contentious issue of data formats, that is, the logical structures (grids, geometry, embedded metadata, etc.)

From page 56...
... In 1979, President Jimmy Carter transferred the Landsat program to NOAA. In 1983 President Ronald Reagan directed NOAA to place the program in the hands of a private corporation.

... In general, a disruptive change whose consequences can be contained between system interfaces stands much less chance of disrupting the entire system. USER EDUCATION As discussed above, there is a wide range of data users, from high-end users such as the numerical weather prediction centers to companies providing products derived from satellite data to individuals logging on to retrieve imagery to guide decisions about recreation.

... For these users to effectively transition to working with digital data, additional educational needs must be met that include adequate training to efficiently locate, acquire, and manipulate digital data files. For all levels of user sophistication, education is a nontrivial undertaking, and, to some extent, user education requirements can be mitigated by adhering to current standards and practices.

... A second approach to gaining user participation and better suited for seeking guidance for planning future satellite observations is the convening of user workshops. These can, for example, be focused on a specific observable, such as soil moisture; on a possible mission, such as measuring sea-surface salinity; or on the suite of instrumentation to be flown on a family of satellites, such as NPOESS.
