Tomas Straupis — Vector Tiles: Lessons from Eight Years in Production

After nearly a decade of utilising vector tiles in both hobbyist and commercial projects, it has become evident that even GIS experts often harbour misunderstandings about this technology. These misconceptions can lead to incorrect usage—or even avoidance—of vector tiles altogether. This presentation aims to address the core principles of vector tile technology, providing the clarity needed to make informed and effective usage decisions. Tomas is a Head of GIS department at iTree. 20 years of experience in IT: analysis, development, testing, processes, quality management. Specialising in using open source technologies, replacing legacy commercial software with open GIS. Recorded at the State of the Map Baltics 2026 / Baltic GIT Conference 2026 in Riga.
