Nov 1, 2024Month: 2024-11. Focused on delivering a major enhancement to the publication workflow in finnishtransportagency/geoviite by implementing an Enhanced Publication Preview and Staging Workflow with Map Visualization. The work centralized geometry-change tracking for location tracks, introduced map-based visualization and selection of publication candidates, and enabled staging of changes within publication groups. UI/UX refinements improved the preview table and map interactions, enabling faster reviews and fewer manual steps. A set of UX-driven PoCs and backups (Preview improvements POC and backup publication candidate map presentation) were conducted to validate resilience and UX readiness. These efforts contributed to a more reliable, auditable publication process and improved decision support for map data releases.
