Hillshade

Hillshade is a raster dataset visualising the elevation of the terrain. There are five product versions available in which the pixel sizes are 2, 8, 32, 64, 128 and 512 metres. Pixel size 2 m has been produced of the dataset Elevation model 2 m and it does not cover the whole of Finland. The other sizes have been produced of the dataset Elevation model 10 m and they cover the whole country. The material does not contain elevation values; it is a greyscale image that visualises the direction and steepness of hills.

The product belongs to the open data of the National Land Survey of Finland. More information: Topographic data and how to acquire it http://www.maanmittauslaitos.fi/en/maps-and-spatial-data/expert-users/topographic-data-and-how-acquire-it.

Purpose:

The dataset Hillshade can be used as a background map material to visualise the elevation of the terrain. Together with the dataset Elevation zones (opacity 15–50%), Hillshade shows the topography and elevation of the terrain even better. It can be used as transparent also together with a topographic or background map to visualise the topography of the terrain.

Maintenance

The rasters have been updated as a whole in October 2015. Changes in the source data are taken into the rasters every month.

Updating frequency:

Hillshade (2 m): The product is maintained if needed, but the area of coverage is expanded continuously. An up-to-date map of the area of coverage: https://hkp.maanmittauslaitos.fi/hkp/published/fi/c206f60e-04b3-45c1-963c-d3d6a35e3552

Hillshade (other pixel sizes): Areally limited and occasional updates are made in the dataset in connection with the regular maintenance procedures of the Topographical database as there are changes in Elevation model 10 m.

Lineage

Elevation model 2 m, which does not cover the entire country, has been used as the reference dataset data for Hillshade 2 m. Elevation model 10 m, which covers the entire country, has been used as the reference dataset for other pixel sizes.

The solar elevation angle used is 45 degrees. The altitude has been enhanced by using a Z-factor as follows:

Hillshade 2 m: 3-fold

Hillshade 8 m: 5-fold

Hillshade 32 m: 5-fold

Hillshade 64 m: 10-fold

Hillshade 128 m: 10-fold

Hillshade 512 m: 15-fold
