- objectives
 to develop and test methods for delivering
geospatial data to a mobile user by means of
real-time data-integration and generalisation
 to create a prototype of a seamless data service
providing access, through a common interface,
to the primary topographic geo-databases
maintained by the National Mapping Agencies

Subobjectives
1/6. Real-time generalisation for mobile
devices
Development of methods and usage
practices for generalising the graphic
representation of geospatial data in realtime, to be suited for display of the data
in varying scales on small, mobile devices
with different display resolutions.

... subobjectives
2/6. Harmonisation and real-time
integration of geospatial data
Investigating the problems between national
primary geospatial databases, often mutually
heterogeneous in thematic definitions, and
developing means for real-time integration of
data.

3/6. Requirements for mobile use
Analysis of mobile use cases to adapt
real-time generalisation and
harmonisation of geospatial data to
the requirements of a user in varying
usage situations.

4/6. EUREF - map projections in real time
Development of methods for real-time
transformation of spatial data from different
national geo-databases to a common, EUREFbased co-ordinate system.

5/6. Test Standards for vector-data
Investigating and developing methods for
transferring vector-formatted spatial data to a
mobile user using emerging standards, like XML,
and testing the applicability of the standards for
Web-based spatial services in a international
pilot project involving national primary geodata
sets.

6/6. Prototype system as a testbed
Development and implementation of
a prototype system that can be used
as a test-bed for the developed
methods.

Technology
 based on the principle of distributed GI
databases
 XML/GML are planned to be used
intensively
 solutions to be based on earlier
research on WebGIS, see e.g.

Summary
 GiMoDig has started
 the project can serve NMAs and
their clients as a test environment
for XML/GML technology
 mobile use sets new requirements
for GI services, e.g. in real-time
generalisation
 first effort in Europe for the
harmonisation of large scale data
