- 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 real-time, 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.

... subobjectives
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.

... subobjectives
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, EUREF-based co-ordinate system.

...subobjectives
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.

... subobjectives
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. www.fgi.fi/osastot/karto/julkaisut/julkaisut_eng.html

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
