This project focusing on modernisation of the spatial data infrastructure is financed by EEA and Norway Grants 2014-2021, under the Climate Change Mitigation and Adaptation Programme, As Norway and Iceland are the donor countries for the financial mechanism, the Norwegian and Icelandic mapping authorities are involved as donor project partners, responsible for assisting with project management and quality control, as well as knowledge transfer and training.

Background challenges

Orthoimagery and digital terrain data is not publicly available in Slovakia, nor were they re-usable in order to support the goals of the main relevant EU policy tools (PSI, INSPIRE). Data are constantly procured by many public sector authorities individually just for their internal needs with no coordination and no machine-readable access with open license, and there was is no direct legal obligation to maintain and share these resources in a coordinated and interoperable manner.

Responsibility for the reference datasets is unclear, and work is underway to identify the barriers and possible options for a solution to ensure legislative requirements for orthoimagery. The main problem and the reason for the current state of play in this field that has been identified is the fragmentation of geospatial data ownership and the lack of cooperation and coordination among line ministries and government agencies.

Slovakia is also facing several challenges regarding the INSPIRE implementation. In the near future, a system for handling procured metadata called the ‘Spatial Data Registry’ will be operational allowing stakeholders to create and publish INSPIRE metadata, but will not provide support for data harmonisation and relevant spatial data services. A national geoportal with harmonised spatial data and services to create the base for a spatial data infrastructure in Slovakia and to achieve the minimum level of interoperability defined by INSPIRE does not exist.

Furthermore, the public administration in the Slovak Republic currently does not have a sufficiently precise digital landscape model of the territory of Slovakia. Such a product is missing mainly in the agenda of public administration in the field of environment and its protection, where knowledge of the shape of the landscape in the form of accurate digital terrain model is needed. As a result of rapidly changing landscape, largely due to human activity, it is necessary to collect and update spatial data by a method that is highly effective, powerful and fast. Such a method is now airborne laser scanning and landscape imaging.

With a database of Orthoimagery Data, Digital Terrain Data and the results of the project, the project partners involved will be able to provide reusable data freely to the public sector as well as the private sector, demonstrating the power of harmonised infrastructures in a wider context.


  1. Development of a Digital Terrain Model (DTM) of the Slovak Republic using data from airborne laser scanning (ALS) and Orthoimagery (OI)
  2. Setting up and developing  a centre for processing of OI and airborne laser scanning and for digital terrain model update
  3. Training of internal employees, transfer of best practices from donor partners
  4. Publication of electronic services via national geoportal

*Airborne laser scanning will also be done, although it is not financed by this project.
