We turn geodata
into decisions
that matter.

A company preparing documents for more than 500 Slovak municipalities needed a reference map it could maintain without a developer. We built a lightweight web map with an admin panel: a colleague types the name of a municipality, the national register fills in the district, region and coordinates, and the public map is up to date immediately. The whole dataset can be downloaded back at any time as CSV, Excel or GeoJSON.

In 2020, we organised the first ever Missing Maps mapathon at the Prešov Region offices — a landmark event mapping marginalized Roma settlements that had never appeared in any official dataset. Working with geography students and experts from Prešov University, our team conducted field surveys in six pilot municipalities, digitizing building footprints and conditions directly into OpenStreetMap.

Using QGIS and Mergin Maps, we designed and deployed end-to-end field data collection workflows for the Prešov Region — capturing suburban bus stops with schedules and accessibility data, outdoor advertising structures, bridge conditions and building registries. GPS-accurate records collected on mobile devices flowed directly into the regional geospatial database, ready for analysis and planning.

We designed and delivered a multi-year QGIS training programme for the Prešov Region — turning civil servants, architects and urban planners into confident GIS practitioners. Courses covered open data workflows, spatial analysis, geoportal use and field data collection. The curriculum was later adapted as a national reference for other Slovak regions seeking to build their own GIS capacity.

From 2017, Geosupport became an official Data Visualization, Data Analysis and Data Science partner of HowMuch.net — a US-based financial intelligence media platform. Under a signed cooperation agreement, we produced over 50 economic maps and infographics including state-by-state analyses of US trade, income, taxes, real estate and GDP. Several visualisations were picked up and republished by international media.

Jana, as President of the Slovak QGIS User Group, co-organised the 2024 QGIS User Conference in Bratislava — the flagship annual gathering of the world's largest open-source GIS community. Hosting the conference in Slovakia raised the international profile of the region's open GIS ecosystem and brought global contributors to Central Europe.

Jana and Miloslav co-edited the EUthmappers Handbook — a freely available guide for high school teachers to integrate open geospatial tools including QGIS and OpenStreetMap into STEAM education. Published under Erasmus+, it is used across European classrooms and serves as a bridge between geographic education and civic digital literacy.
