Description
The product shows the position and direction of ice grooves. Ice grooves have arisen when blocks, stones and gravel grains that have been frozen in the bottom parts of the inland ice have scratched and ground the bedrock surface. The grooves show the direction of movement of the ice at a certain stage. The directional indications (360 degrees system) refer to the direction from which the ice has moved towards the observation site. In some cases, the product contains information on the relative age of different ice railing systems at the same observation site. Positioning accuracy may vary depending on the map data used in the collection. The accuracy of the directional indications can be estimated at +\- 5 degrees.
