3. THE NETWORKING ISSUE
Participants of MISSION will work with similar datasets, at
least in respect to MOMS-02/Priroda imagery. They also
may use in common derived products like geocoded data,
digital elevation models or existing geo-databases. Results
from one group may as well be relevant for another one.
There is a strong demand for information, data distribution
and exchange. These issues have a strong networking
component, which is to be covered by the Datapool task.
Datapool neither is a very specifically tailored information-
facility as ISIS by DLR (Strunz and Lotz-Iwen, 1994) nor
just a general framework for project management issues.
Model and motivation for our plans are the current efforts
of the European Commission launching the Centre for
Earth Observation CEO (Churchill, 1995). Our goal is to
establish within MISSION a strong Austrian branch of the
CEO, where most important institutions are contained.
3.1 CEO as a Model
By 1995, the CEO ended its "Pathfinder Phase". Based on
applications studies, now the design is to be implemented.
Contrary to its name, CEO is to be a loose organized
decentralized network, which is expected to stimulate the
market for remote sensing data by supporting the provision
of new products and services. There are no intentions of
establishing new hierarchies, but the system shall be as
open and flexible as possible. Informations, data and
services may live and develop on their own, independent
of central organizations and facilities. However, CEO will
edit recommendations for data-quality, terms of advertizing
services etc., which are expected to be acknowledged by
data-providers, customers and researchers as well.
According to this model and the specific requirements of
MISSION, the framework to be set up has several goals:

Planned Services
Organisatorial issues:
Project-coordination for MISSION:
contacting German organizations DARA and DLR,
for acquisition-planning and data-dissemination:
organization of project meetings twice a year;
compilation of project reports and documentation:
public relations issues (employing various media).
Implementations:
Establishing Hyper-G-based communication and
data-dissemination within the project;
providing simulated optical data (see Fig.2);
exploiting high performance transfer capabilities
using ATM (Walcher and Rehatschek, 1995);
organization of decentralized preprocessing (e.g.
geocoding) within the MISSION-participants;
developing JAVA-based query- and retrieval-tools;
links among the partners to implement a distributed
database within the MISSION-group;
establishing the core of a CEO-oriented Austrian
group of remote sensing scientists, providers and
applications-oriented users.
Network-based services:
Original image-data (e.g. from MOMS-02/Priroda or
other satellites);
preprocessed data (e.g. geocoded or radiometrically
corrected);
existing topographic databases provided by
participants (e.g. DEM data);
optional controlled disstribution of remote sensing
images and other data (for copyright reasons);
products and results made available by individual
partners (e.g. landuse data);
provide project- and product-information to the
scientific community and the public on the net.
