Development and use of transboundary GIS:
Lake Peipus experience
background A ”test” of GIS component of the EU Water Framework Directive Transboundary river basins on the Eastern Fringe of Europe Lake Peipsi - Europe’s largest (area wise) transboundary lake. EE, RU, LV.
Bilateral agreement EE - RU. Key issues: Eutrophication and fisheries. Project: Feb 2001 - Jan 2004, 12 partners, 6 countries NO, EE, RU, NL, PL
& SE GIS work 5 partners
EE Tallinn Technical University, Center for Transboundary Cooperation
RU State Hydrometeorological Institute
NL Utrecht University
SE KTH Royal Institute of Technology
Overall aims
To create a freely available and easy accessible multi-thematic GIS database of the entire river/lake basin for Modelling Assessment Strategic desision making
To assess the feasibility in developing such a GIS database in light of the (at that time) upcoming WFD ’requirements’
Specific purposes
Serve the spatial data needs for the POLFLOW and MESAW nutrient models
Serve the GIS data requirements in the WFD in support of the Bilateral Commission
Serve the GIS data needs for WebGIS (within MANTRA-East project)
Serve the GIS data needs of other upcoming major projects incl GEF, TACIS
Known challenges
Technical Unequal data
availability Data quality and
characteristics Harmonisation
Institutional Networking Legal constraints Data sharing issues Agreement on detailed
common system
Methodology – main steps
Identification user needs Primary intra-project + WFD WG GIS
Inventory & aquisition of data Characteristics and legal constraints
Harmonisation within and between GIS layers Intra-, inter-, geodetic-, thematic-
Use Modelling, river basin characterisation, WebGIS
Documentation Report, meta-data
Dissemination Web, report, CD-ROM
Results
A GIS database with 26 layers
Distributed on CD and via web
Meta-data Documentation
Lessons Learned - Conclusions Drawn
Diverse region Data quality and
metadata Availability of digital
sources Easier to access and
assess data from MSAC countries
Copy-right restrictions upon GIS data prevent re-use and dissemination Measures:
Sub-optimal data was choosen
Data was degraded
