| Description |
Comprehensive national vector dataset modeling Finland's stream and river networks. It covers all watercourses with an upstream catchment area of at least 10 $\text{km}^2$, as well as smaller watercourses deemed significant for water management and water framework directive (WFD) reporting. The dataset contains linear stream segments (Uoma10.shp) attributed with unique identifiers (uomaNro), flow directions, and physiographic metrics, alongside topological node points (Uomasolmupisteet.shp) marking stream sources, outlets, and confluences. |
