Jaakko Lehto enhanced the QField exercise documentation in the GispoCoding/master-training-data repository, focusing on improving data-entry workflows and onboarding for field data collection. He updated installation instructions, clarified menu options, and refined GeoPackage creation settings by standardizing coordinate systems and layer naming conventions. Using R Markdown and leveraging his expertise in GIS, QField, and QGIS, Jaakko restructured attribute form configurations to streamline offline data capture and reduce input errors. The work prioritized documentation quality and repeatable workflows, resulting in more efficient onboarding and higher-quality field data, though it did not involve bug fixes or major new feature development during the period.
