Historic maps in the SLUB

Jacob Mendt | @jacmendt 2015-09-17, Free and Open Source Software for Geospatial Conference - Seoul

 177.770 analogous historic maps

and panoramic views

  • Focus: History of the Federal State
  • f Saxony

 Over of them are digital available  The portal “Kartenforum” allows

user to search the maps by thematic criteria and display them in as zoomify tiles in a browser http://www.slub- dresden.de/sammlungen/karten/

 5.700 georeferenced plane survey

sheets (with crowdsourcing and automatic image recognition)

 Most georeferenced maps have a

coordinate precision between 5 to 30 m.

 Only 1% of the georeferenced

maps have less then 100 m coordinate precision

  • Reasons are damaged images or in

the case of crowdsourcing evil users

 Portal as TYPO3 extension

  • Stronger modularization

 Support of further map types through the crowdsourcing

georeferencing tool

 Publishing of new map collections through the portal:

  • Plane survey sheets with scale 1:100.000
  • Geological maps

Jacob Mendt | @jacmendt 2015-09-17, Free and Open Source Software for Geospatial Conference - Seoul

 Graphical web based ETL modelling tool that serves to:

  • import data from heterogeneous sources with different formats
  • map input to output schemata and design transformation workflows
  • load transformed data into property graph database

 With additional functionalities:

  • Exporting of data models as RDF
  • Sharing mappings and transformation workflows

 Publication under Open Source licence (Apache 2):

 Is missing spatial functionalities yet.  Could be used to allow the mapping of location names / tags

again Gazetteer  Historic Gazetteer

 Could be further extended with transformation capabilities for

spatial data  It’s up to the Use Case

Preservability: several

thousands of years

Preservability: around 6 years

Digital preservation

Jacob Mendt | @jacmendt 2015-09-17, Free and Open Source Software for Geospatial Conference - Seoul

 Ensures that digital information of continuing value remains

accessible and usable (50 years +)

 Consideration of future usage scenarios  Digital preservation is not a Backup  Two main tasks:

  • Bitstream preservation – Preservation of the correctness of the digital

information (Hardware & Software failures, attrition, hazards)

  • Content preservation – Preservation of the interpretability and usage
  • f the digital information (File formats, Metadata)

the hard part

Digital preservation

Content preservation

Jacob Mendt | @jacmendt 2015-09-17, Free and Open Source Software for Geospatial Conference - Seoul

 What should be preserved?

  • Selection criteria und content evaluation

 Whichdata formats should be used for preservation?

  • Open specification, no proprietary format
  • Wide usage
  • Low flexibility
  • No security mechanism (encryption, copy protection, …)
  • Self-description
  • Robustness
  • Low dependencies from specific software, hardware or other

resources

A spatial view

Jacob Mendt | @jacmendt 2015-09-17, Free and Open Source Software for Geospatial Conference - Seoul

 Demand in the spatial IT area for data management systems,

which support digital preservation tasks

  • Federal agency, private companies, culture heritage institutions, …

 Do has spatial data specific requirements to digital

preservation?

 What data formats should be used for digital preservation of

spatial data (Raster / Vector / Metadata)?

  • GeoTIFF could be a candidate for raster
  • GML could be a candidate for vector, but quite complex

Conclusion

Jacob Mendt | @jacmendt 2015-09-17, Free and Open Source Software for Geospatial Conference - Seoul

 There are multiple points of contacts between the culture

heritage domain and the spatial IT

 Culture heritage institutions are starting to redefine there roles.

This leads often to a new commitment to “Openness”. In practice that means:

  • They try to open their data silos
  • They try to get involved with knowledge communities and support

them  Culture heritage institutions need time to react and change, but

when they change they bring the benefit of an longterm perspective with them.
