    • Remote access to census micro data

  • Tour of the new website

  • Historical GIS for the Netherlands


Introduction to census project
Introduction to census project

  • 1997 - 1999:

    • Scanning 200 books, 42.500 pages

    • Data-entry census 1899

  • 2002 - March 2004:

    • Validation and correction of census data 1795-1859 and 1930

    • Digital archiving census 1960 and 1971

  • March 2003 – December 2005:

    • Life Courses in Context (see: http://www.lifecoursesincontext.nl)

    • Data-entry of census data 1869-1956

    • Documentation, harmonization, access and research


What has been realized
What has been realized?

  • New website up and running

    • Only in Dutch! 

    • Some 40.000 pages of tabular (aggregate) census data downloadable from website

    • Documentation is available

    • Validation and correction are partially complete

    • Harmonization schemes for certain census variables

  • (restricted) Access to original micro data files for 1960 and 1971 census

    • Van Tubergen & Maas (2005)


Still to do
Still to do…

  • Finishing validation and correction

  • Building harmonization schemes for census variables:

    • HISCO for harmonization of occupations

    • Standardizing sub municipal divisions

    • Harmonizing other variables and categories

  • Linking to Life Courses data from the Historical Sample of the Netherlands

  • Better access to the data

    • Data not only as Excel spreadsheets

    • StatLine or Nesstar? Or other publication tool?

  • Translation of the website to English!

Boonstra s nlkaart
Boonstra’s NLKaart

  • Dr. Boonstra’s NLKaart;

    • mid 1980’s onwards

    • first Historical GIS?

    • municipal boundaries

      between 1830 - 1990

    • first SAS/Graph based,

      later MapInfo


Hgin a historical geographic information system for the netherlands
HGIN; a Historical Geographic Information System for the Netherlands

  • Project goals:

    • Converting and correcting Boonstra’s NLKaart

    • digitizing maps with sub municipal boundaries ‘wijken’ (neighbourhoods) and ‘buurten’ (blocks) (1920 – 1971)

    • Setting up a gazetteer of historic places

    • Making the everything available on the web


Hgin details technical stuff

  • Scalable Vector Graphics

  • Geoserver as basic geographical data server (OpenGIS)

  • User friendly interface in NIWI’s Content Management Software: i-Tor

    see: http://www.itor.org or http://www.nidi.nl for working preview of the GIS.


Hgin details results so far

  • Testversion of mapping application is running at NIDI’s website (www.nidi.nl)

  • 1960 and 1971 sub municipal maps available

  • 1930, 1947 and 1956 maps are being digitized (outsourced)

  • NLKaart converted to ArcGIS

  • Work on gazetteer started
