Mission Report of the Visit to the NMA and NGI of Poland and Romania Meeting of the workshop on GI/GIS matters for Phare countries Luxembourg, 24/10/2001 T. Steenberghen A. Willekens D. Vandenbroucke

Objective of the Missions Gain in-depth understanding of the use of GIS in mapping agencies and statistical institutes of candidate countries More detailed information than the questionnaires Luxembourg, 24/10/2001

Example: Comparison Based on Questionnaire Results Poland: NSI  very little GIS experience, NMA  rather well developed GIS expertise, long tradition of GIS use Romania: NSI  little GIS experience NMA  well developed expertise, Restricted use of data set Luxembourg, 24/10/2001

Main Differences, Based on Missions: Extent and Intensity of the Use of GI and GIS Poland, - Different institutes have a lot of experience and/or knowledge about the use of GI and GIS - HOGC is using different GIS software packages - Previously privileged high - resolution Russian satellite images access Romania - Institutes started using GIS later - Use of GIS is rather limited - NOCGC is carrying out interesting GIS projects, mainly for local authorities Luxembourg, 24/10/2001

Main Differences, Based on Missions: Funding and Plans Poland - CSO: EU-funding (Phare projects)  needs assessment  plan to develop a central unit in charge of central services and data bases for GIS Romania - Suffers from limited financial and human resources - One of the main objectives = build a complete digital data base based on the existing topographic maps Luxembourg, 24/10/2001

Main Similarities, Based on Missions NSI Mainly focused on statistical mapping More use of GIS planned with new census Few overlays: - statistical data / topographic map elements - Poland: also overlays with soils and crops layers Most use of GIS: demography, agriculture, environment Main users = ministries Luxembourg, 24/10/2001

Main Differences, Based on Missions Poland Clearly defined procedure for changes to administrative boundaries (NMA), names (NMA), codes (NSI) Informal agreement for data exchange NSI-NMA (formal agreement in preparation) Romania Commercial supplier of administrative boundary data No standardized quality control for errors (no problem since used for small scale mapping) Unresolved problem of update procedures Limited co-operation Luxembourg, 24/10/2001

Issues Requiring More Detailed Analyses Subdivision of administrative data: Administrative boundaries in line with NUTS regions Poland NUTS 4 (Powiads) important level for statistical data Romania subdivision of NUTS 5 with link to build-up areas and link to localities data (typology of urban areas) Luxembourg, 24/10/2001

Main Similarities, Based on Missions NMA Large, traditional organizations Very pronounced administrative structure, with local entities in charge of data gathering, field control, … Focus on traditional mapping NMA in charge of cadastral maps Luxembourg, 24/10/2001

Main Differences, Based on Missions NMA Poland Head office of geodesy and cartography = only department responsible for topographic data More systematic approach of data issues (standardization committee, …) Romania Military department of topography also deals with topographic data Luxembourg, 24/10/2001

Main Differences, Based on Missions NMA Poland Head Office of Geodesy and Cartography has special duties, not generally part of NMA Also responsible for national register of geographical names Cost recovery policy Romania Recent period of restructuring Works most “on demand” for local authorities and other users using topographic information Link to other databases is weak Luxembourg, 24/10/2001

Conclusions of the Overall Similarities and Differences Although the current GIS practice, as it appears from the questionnaire, is not so different, Poland has better perspectives, mainly due to: - Funding (Phare) - Systematic approach to data issues - Co-operation efforts between NMA and NSI Luxembourg, 24/10/2001

Important Issues Discussed Poland 1. The use of gis 2. Geographical units and nomenclature 3. The issue of data ownership - data exchange between nsi and nma - cost recovery - legal basis for protecting ownership of data 4. Gi characteristics of boundaries - changes to spatial statistical units 5. Organisational framework Luxembourg, 24/10/2001

Use of GIS, Based on Questionnaires Poland NSI  mostly visualization NMA  mostly visualization, also analysis, thematic mapping Luxembourg, 24/10/2001

More in Depth View on the Use of GIS, Based on the Mission Poland GIS = maintenance instrument of administrative data bases (head office of geodesy and cartography). Data collection and aggregation boundary maps = based on CSO’s territorial register. Address information = included in CSO data, related to the territorial units. Updates: CSO  Some of the maps used by CSO are provided by the mapinfo supplier, and are used without major changes. The regulation on new powiats, that will enter in effect on january 2002 will require updates of these maps Luxembourg, 24/10/2001

More in Depth View on the Use of GIS, Based on the Mission Poland GIS use for arithmetical manipulations and to generate statistical aggregate data from geographical details (limited, agriculture and environment statistics division of CSO) GIS for the production of map based presentations (currently the main use) GIS for easier user access to the data. This is currently not implemented. (Will be possible when considered in the new NMA-NSI data agreement currently in preparation) Luxembourg, 24/10/2001

Geographical Units and Nomenclature Poland Head office of geodesy and cartography: developed own software for maintenance of official names (not linked to GIS) Boundaries updates in GIS Luxembourg, 24/10/2001

Data Ownership Poland GIS centre to be developed in Ĺódź will be responsible for technical issues of data exchange. CSO Warsaw for organisational issues Cost recovery: general indicators free of charge, other data require subscription Legal basis for protecting ownership of data: no restrictions on use of official statistics Luxembourg, 24/10/2001

GI Characteristics of Boundaries Poland Responsibility of the Head Office of Geodesy and Cartography, annual changes in the boundaries of Gminas Scale: 1/50.000, exceptionally 1/10.000. Regional data disseminated based on the administrative division, (1/100.000). Pilot applications (city statistics) 1/10.000 and 1/20.000 3 level structure since 1999. To be evaluated after two years. The number of Voivodships will stay. In January 2002 the number of Powiats will change. When substantial changes occur (i.e. 1999), time series are recalculated. Luxembourg, 24/10/2001

Organisational framework Poland Interaction Vovoidship - central offices based on national agreement Also local co-operation examples between NMA and CSO (varies) Luxembourg, 24/10/2001

Use of GIS, Based on Questionnaires Romania NSI  data capture and editing, visualization, analyses, thematic mapping NMA  data capture, cartographic production, visualization, analysis. Restricted use of data set Luxembourg, 24/10/2001

More in Depth View on the Use of GIS, Based on the Mission Romania Use of GI and GIS at INSSE = preliminary phase = mainly for statistical mapping based on data coming from different thematic departments (different formats). GIS service links information to basic administrative layer to produce choropleth maps, pie-chart maps, etc. The statistical data are not integrated in one comprehensive data base system as is the case in EUROSTAT for the REGIO and SIRE data bases. GIS service acts as a central service to potential clients (departments). This situation is comparable to DG AGRI where the GIS service is also mainly a central service. aggregation of statistical data not frequent Luxembourg, 24/10/2001

Geographical Units and Nomenclature Romania INSSE: commercial data. Errors were eliminated, but changes not documented. This makes it difficult to track changes over time. Luckily, the administrative data that are used most by the INSSE do not often change and the nomenclature is fixed with the use of the SIRUTA codes. NOCGC: builds all its data layers starting from the topographic maps (mainly 80’s) Luxembourg, 24/10/2001

Data Ownership Romania No data exchange NSI-NMA NMA owns data No collaboration with DTM Cost recovery: no policy Luxembourg, 24/10/2001

GI Characteristics of Boundaries Romania Administrative data base of INSSE = a snapshot (specific time) + can’t be used broader than the INSSE itself. + NOCGC data have higher level of detail  in the future, the administrative data base of the NOCGC could be used as starting point The administrative boundaries, railways, rivers, ... 1/50.000 Elevation contour lines 1/25.000 (interval 20 meter). Also version at 1/500.000 Luxembourg, 24/10/2001

Organisational framework Romania Mission and preparation for the Workshop on GI and GIS improved co-operation Luxembourg, 24/10/2001
