Tiivistelmä: The Shoreline10 (Ranta10) is a topologically correct spatial dataset containing data on Finnish water bodies. The dataset is based on the topographic database of the National Land Survey of Finland in scale of 1:5 000-1:10 000 from years 2000-2008. The dataset contains lakes as well as most of human-made lakes over 200 m2 and more than 5 m wide rivers (polygons). Also included are the main flow paths of 2-5 m wide and less than 2 m wide streams (lines). The dataset has been reclassified and topologically corrected by Finnish Environment Institute (SYKE). The continuous network has been created by combining rivers to the central lines through polygon rivers and lakes. The dataset includes also unique river codes and lake codes. The river network includes all river segments with catchment areas larger than 10 km². Also other, smaller rivers with smaller catchment areas are included in case they are considered significant for water management tasks (e.g. WFD). Ranta10 does not represent the water bodies defined in the new water act. The change from one river segment to another, with unique river code and information, is located at the junction of the river network. The river code also changes at a connection point of a river segment and a lake. The river network has been created such a way that all parts of the network are linked topologically to each other and have a correct flow direction so that the dataset can be used for analyzing the network. Ranta10 including the river network is dataset owned by SYKE and has same copyright and ownership conditions as other similar datasets owned by SYKE. SYKE applies Creative Commons By 4.0 International license for open datasets.

Sijainnillinen ja ajallinen kuvaus: Ranta10 dataset covering the whole of Finland is based on the lakes and rivers from the topographic database of the National Land Survey of Finland in scale of 1:5 000-1:10 000 from years 2000-2008.
Laatutiedot
Historiatiedot: The river network is based on the shoreline data taken from the topographic database of the National Land Survey of Finland (NLS) in scale of 1:5 000-1:10 000. The source data is from years 2000-2008, after which the geometry data has not been updated. From this collected data SYKE has further developed Ranta10 dataset in scale 1:10 000 for the environmental administration. Ranta10 dataset includes all river and lake polygons as well as the main flow paths of 2-5 m wide and less than 2 m wide streams (lines) from the original topographic database. The topological errors of the database have been corrected by SYKE to create a river network. Ranta10 dataset has been completed in SYKE by adding central lines through polygon rivers and lakes. The river network includes all river segments with catchment areas larger than 10 km². These were chosen in a hydrological modeling process using 25m DEM of NLS enhanced with Ranta10. Local ELY-centers have verified modeled river network and added river segments considered significant for water management tasks (e.g. WFD). The dataset includes also spatial and physiographic values calculated for individual rivers.
Prosessointihistoria Ranta10 dataset is updated to cover lakes and rivers in islands of The Baltic Sea at 13.9.2016. The dataset covers the whole of Finland. The river segments of the river network added 12.5.2015 (362 rivers) and 13.9.2016 (123 rivers) are missing some of their attributes. The attributes will be calculated and added later. The attributes of the lakes belonging to the lake register is mainly updated. Some of the lakes might still have incomplete lake register attributes.
