This document discusses the CityData 3.0 initiative, which aims to reduce barriers and friction that users experience when searching for and accessing geographic data on cities' open data portals. The methodology involves an initial discovery phase to understand user needs and challenges through a survey. Expected outcomes include developing strategies and a web tool to promote greater reuse and discovery of cities' open data, integrating APIs to make data more accessible to developers, and identifying success stories and key features. The initiative will work with several cities to test concepts and gather feedback to improve data quality, usability, and user experiences of open data portals.

4. Geo-C: Enabling Open Cities
• Project faced by a consortium of three universities is supported by a network of associated partners,
which are city councils and companies in Germany, Spain, and Portugal. An international Advisory Board.
• The main goal of GEO-C is to make substantial scientific progress towards the notion of open cities, i.e.
smart cities that are open to all citizens and facilitate participation on all levels.
• Using three core areas in research on open governance: participation, collaboration, transparency [1].
Each strand falls into one of the intersections between the core areas and covers a crucially important
aspect for realising open cities: deep participation, analysis and fusion of city data, and city services.
5. Esr 11: Multi-scale, multidimensional urban information integration,
matching and visualization.
• Contribute to overcome the problem of having several geodata sources and sensors that
have disparate resolutions (both spatial and temporal) which need to be allied together in
order to extract useful knowledge doing analyses and to display the outcome in a variety of
devices, including traditional screens as well as current and coming displays and interaction
devices as AR and wearable technologies.

8. Problem statement
Data Producers Data Consumers
BarriersFrictions
Cities’ Open Data Portals
Legal constraints (47%), Desire to publish results before releasing data ( 54%), loss of credit or recognition (41%) as a major
barriers. n= 825 to 854.
According to Belmont Forum’s Open data Survey - Brigit Schmidt (Schmidt et al., 2016)
11. Problem statement
Data Consumers
Cities’ Open Data Portals
Wasted time
Varying degrees of data quality in different datasets (53%), varying standards in how
data has been gathered (50%), varying formats (49%), understanding how to interpret
and reuse data (37%), as a significant burdens. n= 687 to 731
(Schmidt et al., 2016)
The data explosion along with the open data policies
is increasing data availability.

12. Problem statement
Open Government data not only support transparency of the governments but its reuse in products and services can result in economic
benefits
Vickery, G. et al (2011)
15. Discovery phase
Initial survey to know current frictions that data user
have to faced in open data portals when they are
searching geographic information. Furthermore,
determine which feature are the most valuable for
them when they are using those open data portals.
If you are open data user, and you are familiar with
some open data portals, contribute to our survey to
know your experience through open data in cities

24. Our Use Cases
• Bogotá – Colombia (IDECA)
• Medellin – Colombia (GeoMedellin)

25. What we expect?
• Development a strategy to promote the re-use level and effectively discovery
information available in the city.
• Users (types and needs).
• Success stories and features.
• Proof of Concept:
• Integrator APIs (If is really useful for developers)
• Community (Actors and their roles)
• Real benefits in economic, innovation, and scalability terms.
