Finland a multilingual country

Finland – a multilingual country

  • 5.3 million inhabitants

  • 340 000 km²

  • Finnish and Swedish are the official state languages

  • Saami languages are official in the four northernmost municipalities

    • North Saami, Inari Saami, Skolt Saami

  • Municipality is the basic administrative and linguistic unit

  • The 348 municipalities by linguistic status 1 January 2009:

    • 291 monolingual Finnish-speaking

    • 19 monolingual Swedish-speaking

    • 19 bilingual Finnish–Swedish

    • 15 bilingual Swedish–Finnish

    • 4 multilingual Finnish–Saami

Rymättylä (above) is a monolingual Finnish-speaking municipality (Finnish names above Swedish names) and Nagu (Nauvo in Finnish, below) a bilingual municipality with a Swedish-speaking majority (Swedish names above Finnish names)

Some aspects on the modelling of geographic names

Some aspects on the modelling of geographic names

  • Names as attributes of spatial/topographic objects?

    • In some cases no problem (e.g. administrative units)

    • Often the identity, definition, classification, geometry, and other attributes of these objects do not correspond with the named features in the real world

  • Names of non-modelled features?

    • Elevations, depressions, islands, coastal land formations, stretches of water bodies or even populated places are seldom modelled as spatial objects

    • They all are important places referred to by their names in any type of communication

  • Common approach: separate/integrated names register/database

    • Names are often subject to (national) standardisation

    • Names data are often maintained/supervised centrally by e.g. a national names authority

    • Persistent identifiers can be used to link names data with respective spatial objects

    • Names data may be accessed directly via standard (e.g. WFS) interfaces

    • Feature or name oriented model?

    • A register of named places or a register of place names?

    • Are names attributes of places or places attributes of names?


Geographic names register gnr of nls finland

Geographic Names Register (GNR) of NLS Finland

  • Goals of development

    • Feature oriented model

    • Persistent identifiers for named places and names

    • Integration with the NLS cartographic data production

  • Rationale for modelling

    • Multilingual and multi-names circumstances in Finland

    • Multi-product and multi-scale production environment of the NLS

  • Two integrated parts

    • Place Name Register (PNR)

    • Map Name Register (MNR)


Place name register pnr

Place Name Register (PNR)

  • About 800 000 named places and their names

  • Scale-less, no cartographic information

  • Designed to handle places with several names

  • Includes data on named places, e.g.

    • Type (some 50 feature types; feature type groups)

    • Location (centre point, mouth for a river)

    • Place id for e.g. interoperability (SDI) and change-only updates

  • Includes data on place names, e.g.

    • Spelling (standardised, unabbreviated, correct capitalisation)

    • Language and language status information

    • Place name id for e.g. interoperability (e.g. linguistic purposes) and

      change-only updates

  • Includes objects Place and Place name

Map name register mnr

Map Name Register (MNR)

  • Cartographic multi-scale representation of PNR Place names

  • Includes Map names (occurrences in map) as objects

  • Map name = cartographic text variables set for a PNR Place name

    • Position (lower left corner of the text)

    • Direction (pair of relative co-ordinates (dx,dy))

    • Spacing (whether the (dx,dy) also indicates the length of the text)

    • Bending (polyline of relative co-ordinates (dx,dy))

    • Font (e.g. Univers Medium, Univers Bold)

    • Letter tilt (angle, in degrees)

    • Text size (graphic size, mm/100)

    • Text colour (code)

    • Capitalisation (whether the name is written capitalised in this product)

  • Nationwide Map Name Registers by product/map series

    • Maintenance integrated with other spatial/map data production in respective scales:

    • 1:25 000 (800 000 names, completed)–1:1 million

    • 1:100 000 (200 000 names, completed)–1:2 million

    • 1:250 000 (65 000 names, completed)–1:4.5 million

    • 1:500 000

  • National and international SDI and related projects

    • Interoperability based on e.g. identifiers

    • Finnish SDI, EuroGeoNames, INSPIRE, UNGEGN World Geographical Names Database

  • Search

    • Finding places and names by using their attributes

    • Geocoding and geoparsing, geoindexing

    • Map browsing applications, gazetteer services

    • Automatic positioning and navigation

  • Visualisation

    • Map production, viewing services

  • Research

    • Onomastic research, historical research, archaeology, genealogy etc.

  • Semantic web applications
