  1. MGCP Multinational Geospatial Co-production Program Production of a test cell Ottó Brunbauer Hungarian Geodetic and Mapping Company Ltd., Head of Department for GIS Conference 16.11.2006. GEODESY - ECONOMICS – INFORMATICS 2006

  2. Overview of the Project I. Background of the project: • In April 2003, the countries making in a common workgroup (VaCWG) the world’s digital map in a scale of 1:250 000 held a conference in Vancouver. There the USA’s National Geospatial Intelligence Agency initiated -after the accomplishment of the 1:250 000 scale mapping project, with the wider collaboration of the geospatial intelligence agencies- the starting of a new, Multinational Geospatial Co-production Program. • The objective of the project is the creation of an up-to-date digital map database in 1:50 000 and 1:100 000 scales, based on cells of 1° x 1° adjoined geographical coordinates. This database meets the national / international requirements of anti-terrorism and other global tasks. As a result, there will be vectoral maps of the world available for the participating countries in the ratio of their cooperation. • Another objective of the project, in the interest of time- and cost-efficiency, that the creation of paper based maps to be limited only for the areas of necessity. This assures that the geospatial data is always up-to-date and it is sent to the participants in a timely and adequate manner. GEODESY - ECONOMICS – INFORMATICS 2006

  3. Overview of the Project II. Implementation of the project in Hungary: Responsible for the execution of the project: Ministry of Defense Mapping Office Leader of practical execution: Ministry of Defense Mapping Company Coordination Agency GEODESY - ECONOMICS – INFORMATICS 2006

  4. Overview of the Project III. Objective: Creation of a digital GIS database which is consistent with the data density of 1:50 000 scale topographic maps,10x10, on an area of altogether 8533km2 Duration: 2005 october – 2006 december GEODESY - ECONOMICS – INFORMATICS 2006

  5. The Field of Work 1ºx1º cell – 24 segments 317 pcs. ortophotos ~ 200 GByte 47º0’00’’ 19º0’00’’ 46º0’00’’ 18º0’00’’ GEODESY - ECONOMICS – INFORMATICS 2006

  6. Raw Data I. • The evaluation is primarily based on the raw data of an ortophoto with 50cm field resolution made by the Institute of Geodesy, Cartography and Remote Sensing under the project “Areial Photography of Hungary 2005”. • Scanned and georeferred files of military topographic maps in 1:50.000 scale (resolution: 200 dpi; system of reference: UTM/WGS84; format: GEOTIFF) • Gazetteer of Hungary (KSH, 2003-2005) • GeoNames database • Register of geodetic points GEODESY - ECONOMICS – INFORMATICS 2006

  7. Raw Data II. • Database of towers and high buildings • Database of airports and runways • Legend for the deliverable controlling map sheet (GeoSym legend) • DVOF datafile for the area • AAFIF datafile for the area GEODESY - ECONOMICS – INFORMATICS 2006

  8. Reference System of the Raw Data Digital ortophotos DVOF Topographical maps in 1:50000 scale AAFIF GEONAMES G.BASE POINTS Primary raw material Databases Auxiliary raw material GEODESY - ECONOMICS – INFORMATICS 2006

  9. The evaluation covers: • surface topology (surface objects) • buildings and structures • hidrogeology (drainage network, dams, flood gates…) • air transport (airports...) • road transport (road network, bridges and dependecies of decks...) • railway transport • Earth and its vegetation • public power plants (power plant) GEODESY - ECONOMICS – INFORMATICS 2006

  10. Definitons, terms Object : Object attribute : Surface : Abstraction of the actual phenomena. Charasterictics of a given object. Two dimensional topological primitive. The geometrical realization of the surface is the interface. To every object belongs an attribute table which contains the typical features of the object. The filling of this table with data is being done side by side with the vectoral data extraction. GEODESY - ECONOMICS – INFORMATICS 2006

  11. Topological Model The bases of the semantical model are the objects which are settled to each other in a given reference system. Point-like objects Functional and other surface objects Linear objects Land cover objects GEODESY - ECONOMICS – INFORMATICS 2006

  12. Features of Objects The features of the objects are specified with the filling of the attribute table. Object attribute table GEODESY - ECONOMICS – INFORMATICS 2006

  13. Principles of Evaluation I. Terms and principles of evaluation of the objects: • good quality of the ortophoto for identification – the digital image material must be always considered as the most reliable source, especially in regard to the geometric information • unreliable quality of the ortophoto for identification – additional digital and printed sources are serving as reference and auxiliary material. These are helpful in situations when certain information aren’t at all or not properly displayed on the image material GEODESY - ECONOMICS – INFORMATICS 2006

  14. Principles of Evaluation II. Classification of objects: • Mandatory • Conditional • Optional : Can be evaluated if they are unambiguously identifiable on the ortophoto, but their evaluation is not mandatory Must be evaluated in every case GEODESY - ECONOMICS – INFORMATICS 2006

  15. Principles of Evaluation III. Classification of attributes of the objects: • Mandatory : Must be given in every case • Conditional • Optional Not mandatory to be given GEODESY - ECONOMICS – INFORMATICS 2006

  16. Rules of Data Extraction and accuracy I. The objects are coded by DIGEST (Digital Geographic Information Exchange Standard) Feature Attribute Coding Catalog. MGCP’s Technical Reference Document defines the list of obejcts and attributes that are considered as the minimal content of the generated data in the program’s frame. During the evaluation of the objects the maximal acceptable error (absolute error, three times the medium error) is 25m (CE90%), namely the medium error cannot exceed ±8.3m. GEODESY - ECONOMICS – INFORMATICS 2006

  17. Rules of Data Extraction and accuracy II. Technical Documents: • Specification of metadata • Semantical interpreter model • Evaluation guide • Catalog of objects and attributes GEODESY - ECONOMICS – INFORMATICS 2006

  18. Evaluation Guide I. Content: • Basic evaluating guide, • well-established procedures and expectations, • rules in regard to representation and completeness adjusted to each object, • hyperlink to the detailed evaluation guides in regard to each object, • hyperlinks to other auxiliary documents of MGCP.
