Before submitting an ASTER User Authorization proposal, you
should determine whether the necessary data have already been acquired.
Do this through
NASA Reverb. Previously
acquired data are available to anyone.
Two types of proposals may be submitted from this site. These
- Research proposal for basic or applied research
- Educational proposal
Requests from commercial users are being managed by Japan GDS
under the General Program Request
The user authorization proposal
To become authorized, submit a short ASTER
user authorization proposal
- A brief description of the research (or other project)
- An explanation of how ASTER data would be used
- The credentials of the potential user, and
- The size of the geographic areas to be observed.
Evaluating the proposal
NASA’s ASTER User Authorization Committee will
evaluate your proposal. Educational proposals will be forwarded to NASA
Headquarters for evaluation.
If your proposal is accepted,
you will be notified by electronic
mail, instructed how and when to request new ASTER data, and informed of the amount of new
ASTER data that has been allocated. If your proposal is declined, you
will be informed why the proposal was turned down.
For a variety of reasons, even if a proposal is accepted and
you enter a data acquisition request, there is no
guarantee that ASTER can acquire the requested data.
- ASTER observing resources are limited and different
requests for new data will often compete for use of the instrument at the
- Even if ASTER observes the right area at the right time of
the year, the resulting data may not meet your requirements (e.g.
the site might have been covered by clouds).
