The following conditions are necessary for this purpose:
- An up-to-date knowledge of the parameters and possibilities of
all component elements starting with the sensors up to the data processing
and products finishing. Since all these components have a dynamic behaviour
it is necessary to maintain a careful documentation and updating of the files,
technical literature and computer software. This implies the knowledge of
the possibility of their availability including delivery terms, costs as
well as risk factors;
- The knowledge of the real needs of the existing and potential
users as well as the ways and possibilities of implementation of different
systems and remote sensing processes according to the characteristics of
these users needs concerning the data providing: /a/ "on line” or ’’near the
line" data, "off-line" data and "Data Bank"; /b/ unprocessed data, preprocessed
data, processed data.
- At the same time the evolution of these needs must be known,
under short or long terms;
- The knowledge of the possibilities to achieve a maximum efficiency
for different users and the knowledge of the capabilities of these users
to perform the specific determinations according to demands of the remote
sensing processes. The development research involves also the implementation
of different remote sensing processes by their users.
The proposed problem is: to achieve a remote sensing system which
must be suitable in optimal conditons to the proposed aim under circumstances
of having different series of previous data and records (our country has
also many good photocoverages), knowing other different space records (per
formed or performable) and having the processing facilities.
Just from the beginning we can remark that the optimization process
is not a general one, but it is specific for our case. In the following
we refer to deltaic areas. The optimization process regards both the whole
process and each of its components as sensors, captors, platforms, process
ings, etc.
The technical optimization of the system has the meaning of a
productive orientation; thus, the users demands are compared with the equip
ment and interpretation methods their capabilities considered at the same
time with the operational limits of the system/e.g. the possibility of
incomplete chains of determinations.
On the other hand, the economical optimization regards the choice
of technically performable variants which are suitable to the well-known
aims: to achieve a maximum economic efficiency with a given outlay (maximum
principle) or to achieve a certain purpose with minimum outlay (minimum
principle).
