INSPIRE (PD) — Estonian population density 1x1 km (WFS)

Grid-based population data. Population census data are geo-referenced to the accuracy of the building, allowing data to be aggregated to different resolution grid levels. The squares were aggregated on the basis of the building’s centroid. The data of a building within several squares was linked to the square where the building’s centroid was located. If population data could not be linked to the building (data were linked to the building by address and in some cases the address was not identifiable), the data were added to the middle of the village or census station. Countless homeless people are also connected to the village or department centre. If the square is less than four inhabitants, then the total population of the square is marked “-4”. The 1 km x 1 km square map of the population covers the entire territory of Estonia only in populated squares. Grid-based data is the basis for the competent decision making in the preparation of social plans and development plans, including regional development plans. Grid-based data are used in scientific research, in the private sector mainly in choosing the best location and in defining the target group. The service has squares on two layers — both the L-EST97 cross-coordinate system and the ETRS89-LAEA coordinate system grids. Source of data: Statistics Office
