Report of the Hungarian NMA Workshop for Candidate Countries on GIS Joint meeting with NSIs &NMAs LUXEMBOURG 24 October 2001

Data acquisition for statistics Data sources (from local to global) Cadastre Database of administrative boundaries Remote sensing techniques

Data coming from cadastre Advantages: data coming from the very source: where they are measured, stored, and maintained Type of data Land coverage Owner groups Other indicators (land values) Area of territorial units Technology: operations at database level by means of filtering Data supply on Intranet

Data supply on TAKARNET

Administrative Boundary Database Content: boundaries of administrative territories from settlements to country level Advantages: Commercially available for the whole country Real vector GIS Data source: national cadastre – continous update Reflecting the real legal status od the territorial units Possibility for linking statistical data throogh the statistical identifiers

CORINE land cover Database CLC100 CLC50 Area R 0,25km2 0,04km2 No of classes 27 80 No of polygons 24 000 150 000 (appr) Reliability 80% 90% Interpretation hard copy soft copy Result: topologically structured database

CORINE land cover

Joint projects of HCSO and FÖMI Administrative Boundary Data Services for the CEEC Preparatory works for launching an on-line service of AB data At international level with legal background from primary sources with product differentiation according to common specification

Joint projects of HCSO and FÖMI Remote Sensing and Urban Statistics project - delineation of agglomeration of Budapest by means of remote sending Thematic maps for the Vineyard and orchard census in 2001

Last remark… & Thank you Advantages of the integrated management of cadastre, mapping, and remote sensing & Thank you
