The data files are available in these formats:

CSV File

Hints for automated processing of CSV Files:

  • Characters are encoding in UTF-8 format (without BOM).
  • New-line sequence: CR/LF.
  • Column separator character: Semicolon (;).
  • Text delimiter character: Double Qquotation Marks (").
  • Any column may be quoted by text delimiters.
  • A text column will be quoted by text delimiters whenever it contains either new line, column separator or text delimiter characters.
  • Text delimiters will be doubled when they appear within text.
  • Numbers are shown without thousands separator (e.g. 9999,99).
  • Decimal separator: Comma (,).
  • The first line (header) of each fact file (data file) contain the codes of the classifications and facts being used.
  • Additional information on the fact files are provided in the attribute description and additional metadata.
  • Naming convention for a header file:
    <name of fact with w/o extension>_HEADER.csv
    Naming convention for a classification file:
    <name of fact with w/o extension>_C-A10-0.csv.
  • The heading line of the fact file and the corresponding header file allow for determining the classification and fact titles.
  • The header line structure is as follows - the first two columns are mandatory:
    1. Column "code" — Code as being used in the fact file.
    2. Column "name" — German title.
    3. Column "FK", "FK-..." or empty:
      • "FK": This foreign key refers to the next higher element within the very same file (self-referencing classification). The foreign key is empty when the element is in the root.
      • "FK-..." or empty: Skip this column.
    4. Column "en_name" — English title.
    5. Column "de_desc" — German comment.
    6. Column "de_link" — Link to additional German metadata.
    7. Column "en_desc" — English comment.
    8. Column "en_link" — Link to additional English metadata.
    9. Column "de_syn" — German synonyms.
    10. Column "en_syn" — English synonyms.
  • Titles for classification elements can be determined using the classification file.
  • A classification file may contain more classification elements than being used in the corresponding fact file.

SHP Shapefile

The shapefile format (SHP) is a geospatial vector data format for geographic information system (GIS) software.
A Shapefile consist of more than one file:

  • .shp: shape format; the feature geometry itself
  • .dbf: attribute format; columnar attributes for each shape, in dBase format
  • .shx: shape index format; a positional index of the feature geometry to allow seeking forwards and backwards quickly
  • .prj: projection format; the coordinate system and projection information
  • .cst: used to specify the code page (only for .dbf) for identifying the character encoding to be used

A GeoPackage (GPKG) is an open, non-proprietary, platform-independent and standards-based data format for geographic information.

Web Map Service (WMS)
