- 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


44

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.


55

... 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.


66

... 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.


77

... 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.


88

...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.


99

... 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
