Theme rasters
The themes of the Topographic database and Topographic map raster series (scale 1:10,000) have been compiled into seven theme entities, theme rasters, required by the Inspire directive: hydrography, elevation, traffic network, land use, land cover, place names and buildings. In addition to the above, the theme rasters also include the municipal division, road names and map sheet division as separate themes.
The theme rasters have not been implemented according to the imaging technology defined in the Inspire directive. They will be produced later.
The product belongs to the open data of the National Land Survey of Finland.
Purpose:
The theme rasters are applicable to be used in base maps for planning land use or for excursion and outdoor recreational purposes in mobile devices and in various Internet services.
The background of the theme rasters is opaque so that they can be stacked one on the other and in this way desired map entities can be created.
