societal
opportunities

4. Geospatial Big Data
Raster Vector Sensors Mobile
It’s easier than ever to collect geospatial data,
but how can we exploit these geospatial big data?

5. Example: Property data
One of the most valuable datasets managed by
governments worldwide
Extensively used in various domains by private and
public organizations

6. Challenges in working with property data
• Difficult to access
• Cross-sectors
• Data is highly heterogeneous and possibly large
• Data quality
• Time-consuming integration
• Lack of innovation
• …

7. How can we innovate (and make money)
with property-related (Open) Data?

8. proDataMarket project goals
• To make property data more accessible,
more usable and easier to understand
• To make it easier for:
• Property data providers to publish and
distribute their data
• Data consumers to find and access
property data needed for their businesses

10. Example business case #1
Objective evaluation of the real estate properties
Business Intelligence companies
(e.g. Cerved)
Automation and cost-reduction in
property valuations, new services
Public administration Fact-driven social policy
Real estate agencies Speed up evaluation of properties, more
objective estimation of properties
Property buyers/sellers Eliminate intermediaries

about transport, downtown,
environment
Cadastral report
Property details (surface,
cadastral category, quality
status, age, ownership details)

13. Example business case #1 (cont’)
Objective evaluation of the real estate properties
in Italy, by
Sample technical challenges
Semantic data heterogeneity
How to translate a point of interest
into an OSM query?
How to retrieve data from the
whole Italy?
Structural data heterogeneity
How to compute indicators on
different data structures?
Messy data
How to exclude from computation
duplicated annotations of the same
real-world entities?

14. • Stakeholders:
• Public administration (e.g. FEGA
in Spain)
• Farmers and land owners
• Intermediaries (e.g. service
providers)
• Problems:
• Unfair grant assignment and
expenditure on audits
• Incorrect grant assignments
• Features defined subjectively

Groups, lines, isolated
trees, etc.
5) Trees in line, hedges
Non-aligned groups,
copses
6) A viewer
2) Classified points by
their height
1) Raw datasets,
just points
3) Points are grouped: Yellow
(soil), Green (trees), Orange
(bushes)

Augment Reality (AR) for Property-related Data
in Norway, by
AR for buildings AR for underground infrastructure
What’s the impact of a new
building on its surroundings?
Where are the underground pipes?
