Elevation model 10 m

Elevation model 10 m depicts the elevation of the ground surface of the whole of Finland in relation to sea level. Its grid size is 10 m x 10 m and the accuracy of elevation data 1.4 metres.

The product belongs to the open data of the National Land Survey of Finland.

Date (Publication): 2007-05-30

Unique resource identifier: http://paikkatiedot.fi/so/1000014

Purpose: The elevation model allows for example simulation of receiving, coverage and service areas. It can also be used for mass calculation of excavated material and landfill and for calculating inclinations, steepness or profiles. Application areas are found, for example in geology, geography and forestry.

Pass: Yes

Statement: The elevation accuracy of the product is 1.4 m on average (1.4 m in 95% of the cases and 2 m in 99% of the cases). In the ASCII version the elevation data is expressed in metres (three decimals, e.g. 42.604) and in the GeoTiff version as float values in metres (only the first three decimals are significant). In both versions, objects below sea level have a negative value.

Elevation model 10 m has been derived from Elevation model 2 m in those areas covered by the 2 m model. The elevation value is calculated by interpolating (bilinear) the elevation values of the 2 m model within the 10 m grid. In other areas, Elevation model 10 m has been produced of contour lines made more accurate in connection with the regular maintenance procedures of the Topographical database, of ground surface points digitised in a stereo workstation environment and of all the objects in the Topographical database with a z-coordinate. In these areas, the elevation accuracy of the product is 1.4m on average (1.4 m in 95% of the cases and 2 m in 99% of the cases). In areas derived from the 2 m model the locational elevation accuracy and details are considerably better.
