Fig. 7. FRIMS system architecture (local, regional/national, international level)
ment. satellite communications and multimedia networks. lt
includes the following components (see fig. 7):
I. Data acquisition from the total endangered catchment area by
decentralised environmental sensor sets (hydro-meteorological
data, water levels, dike data etc.) as well as from flooded
areas, actual land cover changes, local ecological, agricultural,
industrial, socio-economical aspects etc.. The data will be
collected in local data centres (LC) by local expert groups. In
case of inaccessible sensor locations the data will be
transmitted to the LC's automatically by VSAT satellite
communications.
2. Information management together with national (NMC)
respectively international (IMC) disaster management centres
and data communication between LC's and MC's via
electronic network or VSAT technology.
3. GIS data management within the MC's.
The NMC's will have access to map archives, satellite remote
sensing data, airborne campaigns, data processing and GIS data
management facilities and represent the central
regional/nationalmanagement and decision unit (,.operational
emergency centre") together with governmental representatives
who are responsible for risk management (e.g. Ministry of
Interior), regional planning (e.g. Ministry of Economy) and
environmental development (e.g. Ministry of Ecology).
The IMC represents the inter-governmental body for operational
activities which are internationally agreed, together with additional
GIS data management and links via multimedia networks to inter-
national experts (e.g. IKSO) and data centres enabling consulta-
tions, diagnoses and international emergency management.
The actual data, authorised recommendations, reports, decisions
etc. will be transmitted back to NMC's respectively LC's through
the VSAT system. The near real-time availability of such results
for the national and local administration will permit:
e high efficient operational flood management (dike regimes,
retention areas etc.) for the assessment of outlet behaviour,
damage prevention and limitation etc.

e appropriate co-ordination of joint international activities across
borders
e further renaturation management and regional development of
the flooded areas
e actual recommendations for decision making, public informa-
tion, policy making etc.
The GIS data management in the MC’s will deal with:
e additional acquisition of satellite and airborne data, geophysi-
cal, agro-meteorological, land cover data etc. including data
processing for DTM generation, land use maps etc.
e creation of the GIS „Oder“ data base through data integration
into a reference system as well as the integration of this data
base with DTM’s, simulation models, expert systems etc.
e GIS spatial data analysis, hydrological and risk monitoring as
well as modelling (simulation, damage assessment) the flood
situation, model calibration and improvement by application
of the GIS
e generation of user relevant data products, scenarios, risk maps,
reports, recommendations for management decisions and
public information
The multimedia electronic network includes data and information
exchange facilities with international data centres and special
organisations, model integration, expert analyses by performing
videoconferences etc.
The main dissemination and further application of the developed
risk and hazard information management system will result in the:
e Assistance in disaster prevention (prediction, warning),
damage assessment, relief hazard monitoring and management
in case of further natural hazards and industrial accidents
(pipeline disasters, chemical and nuclear accidents, forest
fires, land slides, storms, droughts, decline of infrastructure .
etc.)
e Post-accident monitoring, renaturation and land use manage-
ment in disaster catchment areas
e Definition of relevant EO data products for the improvement
of flood management (DTM, land cover, vegetation index etc.)
