• 257 Datasets
• 125 Geodatasets
• Clear licenses
• Machine readable
formats and web

Our open geodata
• Mostly POIs and Basemaps
• But e.g. no cadastre data (buildings, streets, properties)

Threats by open geodata?

9. 10.03.2016
Threats of open geodata?
• According to us:
– …
– Not different than of other data types  Main Concerns:
• Data protection (E.g. mashups or/and small scale)
• Misuse, misinterpretation or publication of obsolete/wrong data
• Administrative costs (data preparation, documentation, resources)
• Transparency
• According to geo data providers
– Legal Barrier: Data under federal or cantonal jurisdication
– Threat: Missing revenues from selling geo data

Opportunities by open geodata?

11. 10.03.2016
• We love geo data! There’s a huge potential
– Technical Geodata-Infrastruture in most Govs
– International OGC-Standards, Interoperability
– Metadata!
– Data catalogs
– Skills and great tools exist (FOSSGIS, OSM, Dataviz-Libs, etc.)
 For us: Most convenient publishing process
Adjusting delivery agreement  GeoServer  Drop zone  CKAN
 High demand
Opportunities with open geodata

12. 10.03.2016
• Reusability!
– Expensively produced geo data, that’s fincanced by the public,
can be used not just by a few, it can be used by anyone for
anything.
• Innovation
– In Zürich more social than economic benefits so far
• More efficient and effective government services
– Do Govs really have to create all Apps / Interfaces themselves?
• New knowledge from combined data sources
• Self-empowerment, Transparency & Participation

19. 10.03.201610.03.2016
• We see by far much more opportunities than threats
• There’s a huge potential in open national geo data!
• The interesting question is: «What are the threats of
CLOSED geo data»
