metadata, changes only)

Figure 4 - EuroSDR new research priorities
Figure 4 shows how the EuroSDR research interest has widened compares to the earlier situation.
Technological issues of the whole geo-information production flow are covered now. The prime field
of interest is still the production of core data, i.e. large and medium scale topographic data; but this is
now dealt with in the setting of GSDI. This means that the link has to be made to the different types of
application domains where this information is used. This is certainly true when we see the shift from
map structured data products to object structured approaches. These imply a higher semantic content
of the data, which requires a better integration with user environments to provide relevant semantics.
The GSDI setting also implies that information management issues have to be dealt with to provide
for timely data delivery and to facilitate the integration of geo-spatial core data with other (geo-
spatial) data.
33 The research structure
The five Commissions of the Organization will implement the new research strategy. Their main task
is to initiate projects and publish their results. The Commissions should also stimulate interaction
between the different parties playing in the field of core data provision and its use. The commissions
are (EuroSDR, 2000):
Commission 1: Sensors, Primary data acquisition and Georeferencing
Its mission is to to explore, demonstrate, and further develop
e airborne and spaceborne sensors for data collection
e calibration aspects of such sensors
e methods and instruments for georeferencing of such data
