In-Depth Information
the information contained in TYPEC array, the statistical mean situation of pol-
lution in the absence of information is controlled.
The system is
filled up with data by introducing the results of measurements
provided either by the monitoring or by the services of control of observance of the
norms of pollutants emissions into the environment by the anthropogenic systems.
The system contains the TYPEP (I,J,TIME) array designed for introduction of more
accurate information about the polluting productions. The TYPEP array includes
productions characteristic of the territory, due to which the system provides the
information network with average estimates of pollutants emissions in the case of
the absence of other information. Information about the characteristic compositions
of sewage in the territory of productions is used as a database.
Depending on requirements for the SSHHI ef
ciency, the corrective information
can be obtained from satellites. For instance, information about the arrays TER-
RITORY, HYDROL, TOPOGR, PARTW, PERTS, VEGETA, VEGETS, and
ANTROP can be obtained from satellites. The arrays TYPEC and TYPEP can be
replenished and corrected by the regular use of the
flying laboratory.
The structure of the SSHHI information base is determined both by possibilities
of its formation and by need of practical solutions of the problems of the water
quality control in a given territory. The gained experience in creation and use of
such systems suggests a hierarchical structure of the database constructed by the
principle of successive digitization of the territory. Following the scheme of hier-
archical digitization of the space, one can, without damage to the system, constantly
increase the minuteness of digitization, with the subject orientation of the territory

preserved. Thus the structure and functions of the SSHHI are adjusted to natural
composition of data on various aspects of functioning of natural and anthropogenic
landscapes. The SSHHI only synthesizes the available data and suggests data that
should be obtained. Models in the SSHHI structure provide an integration of data in
space and by subject areas, due to which an integrated image is formed of the
territory with processes taking place in it.
The SSHHI has a set of formalized structures to control the monitoring regime.
Spatial-temporal identi
fl
ers refer the SSHHI to the topology and morphology of the
natural or anthropogenic object. The sets of the identi
ers enumerated above
parameterize the spatial and subject structure of the territory
, so that at each level
of its spatial digitization a complete description is provided of an image of the
system under study. By the space, the topology of this parameterization can be
heterogeneous and non-uniform as well as excessive.
Following the hierarchy of the SSHHI menu the user, can implement the fol-
lowing operations:
ʩ
to ask for data on any identi
er (array) and to correct any of its fragments;
to ask for estimates of all or part of the parameters of simulation units and to
correct them;
to select the sets of parameters and identi
ers for a more prompt access to them;
to synthesize a symbolic schematic map of the distribution of the estimates of
the environmental characteristics; and
