Open Data
in your city

Open Data is a strategic resource in the development of intelligent cities of all sizes – not only large agglomerations. As part of the service we aid the public entities in fulfilling statutory commitments in the field of data opening and in implementing the process effectively as well.

Open Data
in your city

Open Data is a strategic resource in the development of intelligent cities of all sizes – not only large agglomerations. As part of the service we aid the public entities in fulfilling statutory commitments in the field of data opening and in implementing the process effectively as well.

What is open data?

Open Data are structured data sets coming from city management processes. They are shared on dedicated platforms in the form of files that can be further processed. Thanks to this, city data is subject to analysis and re-use.

What data can we share?

Static data

Data that does not change frequently, such as timetables, list of public transport lines, list of bus stops (including coordinates and functions such as stops on demand), demographic data of cities and districts, statistics about tourist or bicycle traffic.

Dynamic data

Data that presents the current state of affairs, such as GPS positions of public transport vehicles, current delays of public transport, data from Passenger Information Boards, occupancy of parking spaces, measurements of weather stations, air quality or noise level.

Why is it worth to open data?

  • it can be the raw material for building applications, websites or services
  • it contributes to higher participation of residents in deciding about a city or a given region

  • it is a form of cooperation between the public and private sectors

  • it increases the city’s potential for investors
  • it gives transparency and efficiency to the functioning of public administration bodies

  • it positively affects the city’s image aspects

  • legal regulations oblige the public entities to disclose data

The way to open data

Analysis of the situation

  • internal audit in legal and organizational terms
  • developing an open data policy
  • preparing documents necessary to start the process of data opening in the city

System customization

  • inventory of the city’s systems
  • analysis in terms of copyright and types of licences
  • analysis, design and implementation of an open data interface for legacy systems

Implementation of the platform

  • inventory of data sets
  • introducing an open data platform (e.g. CKAN)
  • adjusting the platform to the needs of a public unit, taking into account the dynamic data module

Who shares the data?

Data is disclosed by various entities in order to improve the functioning of both the public and private sectors. The group of organizations that are obliged to make the data public include:


Local government units

Communal companies

Legally controlled persons

Roads and public transport authorities

Units of the public finance sector

State organizational units that are not legal persons

Why are the entities obliged to share data?

Currently, data re-use is an area regulated by the European Union law, hence the new bill was passed in line with EU standards.

Opening of data by the public sector is subject to legal regulations and targeted programs:

  • Directive (EU) 2019/1024 of the European Parliament and of the Council (EU) 2019/1024 of 20 June 2019 on open data and the re-use of public sector information
  • Act on open data and re-use of public sector information passed on August 11, 2021
  • Data Opening Program for 2021-2027 implemented by the Ministry of Digital Affairs

5 levels of data openness

In addition to the legal regulations, consistent “good practices” related to data sharing have been developed in recent years.

1 level

The least open level, where data is shared as photos of a document.

2 level

Data is prepared for machine reading.

3 level

Data is open and the access to it is not restricted.

4 level

The system is fully open and the data is stamped by metadata describing the set.

5 level

Data is connected to other sources so that the context is known.

Opening data step by step

Is there a policy of open data in your city? The process of data opening involves many aspects: legal, technological, organizational and finance. ELDRO TECHNOLOGIE comprehensively guides you through the process of data opening – from consultancies through audits to implementation, taking into account all your needs.

Legal audit

Analysis of local law documents, contracts, ordinances, regulations in terms of suitability for data opening and reviewing licences, data ownership rights and their files, IT systems in which the data was produced.

Preparation of documents and legal acts

Based on the analysis, together with the Customer we will develop an open data policy and necessary local law acts that prepare the office and its subordinate units to the widest possible data opening, at the same time protecting the decision-makers and employees against unlawful decisions and the citizens against violations of privacy.

Organizational audit

There has to be certainty that the organizational structure of the office and its subordinate units will be prepared for the process of data opening and its publication will not be too burdensome and costly for the unit. Therefore, the structure of LGU and its subordinate units will be subject to detailed analysis and description.

Development of an optimal open data implementation project

Data opening requires an interdisciplinary approach – we aid in defining the implementation team and placing it in the structureof LGU. During the process, the people involved will be trained in the legal and technical aspects of data opening.

Technological audit

In order to establish the plan of data opening it is necessary to prepare an inventory of the city’s (source) systems which will allow for determination of the data sets. In addition, the analysis covers the existing server infrastructure and the possibilities of its use, as well as the use of cloud infrastructure.

Design and implementation of the data opening platform

According to the resources and organizational possibilities, the CKAN platform is being implemented, modified with a dynamic data module, which is the most valuable source of information. It is possible to use Google Cloud Platform in the SaaS (Software as a Service) model, thanks to which the LGU does not bear the investment expenses, but constant monthly fees.

Open Data in the press

Open data not only in urban agglomerations”

Data is said to be the new fuel, the new oil of the 21st century that underpins a highly developed information economy. This applies to the same extent to the public, scientific and private sectors. How to share data so that stakeholders can use it freely and why are cloud solutions supporting these activities, getting ahead of the traditional model of building an own IT infrastructure?

Our competences in the field of data opening

ELDRO TECHNOLOGIE is part of the ELDRO Group that has been carrying out investments for the public sector for over 30 years. Therefore, our projects related to technical infrastructure are implemented from design to integration with IoT devices and IT systems.

Operating in the Smart City field, we implement ITS (Intelligent Transport Systems), for which the data sets are of key importance during operation. They are also a source of information for cities that make decisions based on them, and enable the creation of innovative analyses by external entities.

Thanks to our experience in the field of these systems, we have competence in the field of:

  • opening road and public transport data

  • implementing a platform for dynamic data
  • knowing Open Data GTFS-RT and Datex 2 protocols, making it possible to display the GPS positions of public transport vehicles on Google services

  • working with CKAN system – one of the most popular solutions for presenting Open Data

  • integrating with ITS/Smart City systems


Let’s talk about what we can do for Your city in terms of data opening.
