QGIS is an open-source desktop GIS used around the world, and its use is also expanding in Japan across government agencies, companies, and educational institutions. For companies that want to engage with QGIS continuously and provide value, it is important to think not only about using it, but also about their relationship with the community, how they support users, and what role they should play.

MIERUNE has been continuously involved with the QGIS project as a sponsor and commercial supporter. We established a dedicated QGIS team and have supported the practical use of QGIS in professional settings through training, support services, and plugin development. We also share knowledge and practical information through “QGIS LAB by MIERUNE.” In recent years, we have also been working on product development that expands the range of QGIS use cases.

In this presentation, we share practical lessons drawn from real-world work in Japan on how companies can engage with QGIS on an ongoing basis. Through activities related to user support, knowledge sharing, community engagement, and the expansion of QGIS use in practice, we reflect on how companies can contribute to the QGIS ecosystem in sustainable ways.
