FINAL REPORT Challenge 13 [PDF, 6MB]


  • Background of the challenge

Before the the AgriHub Czechoslovakia project1 had started, there was any Geo-ICT platform available in Slovakia. Now, when the project is about to accomplish its mission, this challenge would like to demonstrate how the project helped to improve the situation and what might be the opportunities to sustain the platform and enlarge the community. Challenge has built on top of the Innovation experiment No. 3 Agrihub INSPIRE hackathon 2021 outcomes2.

  • Full explanation of the challenge defining the scope of the effort.

Main motivation of the challenge is to provide access and support for spatial data utilization within agro environmental context. This shall provide support for agri-food Geo-ICT community building process, networking, stimulating innovations and knowledge transfer in Slovakia. Lastly, the team addressed the potential of the platform for future sustainability and improvement.

Challenge has focused on identification of relevant stakeholders and their requirements, investigated available data sources, technologies and supported set of following use cases:

  • Cífer Farm
  • Students´ work and training
  • Agricultural subsidies support
  • Predictive analytics in Agriculture

  • Detailed implementation plan

Challenge has started with the relevant stakeholders’ identification, resulting with interviews with the representatives of farmers, students as well as related added value services providers. Consequently, work on data collection and preparation has started, followed with identification of the user requirements and scoping of use cases.Following activities were focused on use cases implementation in iterative manner and collection of the outcomes and outlook.

  • Analysis of needs of stakeholder groups

This was an important part of the challenge implementation, being aware the target users are a critical precondition to define realistic requirements as a base for further use cases design and implementation.

  • Use cases
    1. Use case #1: Cífer farm
    2. Use case #2: Students´ work and training
    3. Use case #3: Agricultural subsidy support in Slovakia
    4. Use case #4: Predictive analytics in Agriculture

Use case #1: Cífer farm

The aim of the challenge team was to collect and prepare datasets to meet the requirements of farms. Cífer Farm was chosen for this purpose as we were able to establish a connection with the open minded representative of this farm.

The use case featured two processing levels: the first was data collected from Cífer Farm, and the second processed the data that were created for Cífer Farm within the challenge. The datasets produced for Cífer Farm are stored in a single location and are available via a desktop QGIS client application as well as from web browser (see Figure.1).

The second level was linked with data processing for the target farm using the EOBrowser platform. This platform provides the user with support in browse, compare, download full resolution image from all data collection for other data analysis. NDVI datasets were prepared for this farm over a set time period (see Figure 2.).

Use case #2: Students´ work and training

Another use case transferred the approach to the academic environment (see Figure 3.).

The use case also had two processing levels; the first of these concerned education, knowledge base transfer and the training program itself, in which students worked on data collection of the most important data sets for farmers. In the first stage, data were collected for three farms (Poľnohospodárske družstvo BEBRAVA, Poľnohospodárske družstvo Melčice – Lieskové, Poľnohospodárske podielnické družstvo Liptovská Teplička). In the second processing stage, we examined the data collection process for data provided for 25 farms (See Table 1).

Table 1. List of chosen farms

The task was to present the potential and transfer of knowledge base from the education process into the field of agrosector. Students

presented the possibilities of preparing datasets, which are useful for farmers.

The processing approach was divided into two parts:

  1. Preparation of input data
  2. Creation of thematic layers of selected farms

Preparation of input data of selected farm

To obtain primary sources of spatial data, portals of available open data in the conditions of the Slovak Republic and other documents were used, which enabled spatial localization of individual farms according to Table 1. Those groups of datasets were selected which use farmers the most and which will help them in decision-making processes. Specifically, it was a series of these datasets:

  • LPIS,
  • BPEJ,
  • boundary of use,
  • cadastral boundary,
  • boundary of local administrative units,

Creation of thematic layers of selected farms

Postprocessing was performed using ArcMap tools. It was also a series of other procedural tasks:

  • preparation of thematic layers,
  • working with geodatabase,
  • using of geoprocessing tools for automation of the processing process and geospatial analysis,
  • sharing datasets with other users,
  • creation of print reports,

The following figure presents an overview of the obtained outputs for the Farmer’s cooperative Čereňany.

Final reports were created for each farm on the basis of many types of base maps. These reports were supplemented by other cartographic elements such as the legend, the scale of the map, the north arrow (Figure 5).

Use case #3: Agricultural subsidy support in Slovakia

This usecase intended to increase awareness of end users, when applying for the subsidies support in Slovakia. Manz farmers face significant challenges when applying for subsidies linked with digital literacy as well as limitations that occurred during the Covid pandemic period. With that possible improvement has been investigated in connection to the participation of Slovakia on the EU initiative Fastplaform3 aiming to make farmers’ and other stakeholders’ interaction easier.

Use case #4: Predictive analytics in Agriculture

The last use case was devoted to the topic of Predictive analytics in Agriculture. The challenge applied an innovative experimental approach and involved PhD students. We want to mention this use case because it solved an important issue: design and application of a prediction model for crop yield estimation of selected agro-commodities for strategic supply chain management using large data (Big Data) and machine learning. Models (custom made, WOFOST crop growth simulation model) were tested (see Figure 8).

Figure 8. Models under the tests

Following result has been identified:

  • These models have not been tested in the conditions of the Slovak Republic yet.
  • NDVI in custom models had a significant position.
  • Wofost stimulates crop growth over time, from point zero (sowing to harvesting), the conclusions of the test showed that this model is not applicable in our conditions.
  • Highlight of this use case was a custom model. The most accurate model turned out to be three inputs of the components Meteorological data + NDVI + soils characteristic (see next Figure 9).

  • Discussion of the results and findings

Outcomes and experience achieved with this challenge helped to initiate discussion about potential and further outlook of the platform as well as community related agrifood and environment community. It shall be of the joint interest for the whole current project team to sustain the platform and contribute to the further development and enlargement of the relevant stakeholders’ network. There is

significant potential in investment to the platform as current societal challenges calls for innovative solutions with the support from geoict perspective.

  • Further improvements

There has been identified set of possible areas for improvements which can be divided to the two main categories:

  • Platform
  • Maintenance (Plan4all)
  • Further technology development (Plan4all+partners)
  • Content improvement
    • Info content management
      • Jobs, Calls, Events, Contacts
    • Metadata, data/services, map compositions
  • Community
  • Further business development maturation
  • New projects opportunities
  • Networking support
  • Organising events
