Overview of the Project I.

• Background of the project
• In April 2003, the countries making in a
  common workgroup (VaCWG) the worlds digital map
  in a scale of 1250 000 held a conference in
  Vancouver. There the USAs National Geospatial
  Intelligence Agency initiated -after the
  accomplishment of the 1250 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 150 000
  and 1100 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.

Overview of the Project III.

• Objective Creation of a digital GIS database
  which is consistent with the data density of 150
  000 scale topographic maps,10x10, on an area of
  altogether 8533km2
• Duration 2005 october 2006 december

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 150.000 scale (resolution
  200 dpi system of reference UTM/WGS84 format
  GEOTIFF)
• Gazetteer of Hungary (KSH, 2003-2005)
• GeoNames database
• Register of geodetic points

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

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)

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.
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
12
Features of Objects
The features of the objects are specified with
the filling of the attribute table.
Object attribute table
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 arent at all or not properly
  displayed on the image material

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
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
16
Rules of Data Extraction and accuracy I.
The objects are coded by DIGEST (Digital
Geographic Information Exchange Standard) Feature
Attribute Coding Catalog. MGCPs Technical
Reference Document defines the list of obejcts
and attributes that are considered as the minimal
content of the generated data in the programs
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.
17
Rules of Data Extraction and accuracy II.

• Technical Documents
• Specification of metadata
• Semantical interpreter model
• Evaluation guide
• Catalog of objects and attributes

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.
