Estimated number of dwellings in apartment and family houses in Bratislava (grid 250x250m)

Spatial distribution of the population is normally expressed using discrete objects (boundaries of administrative or statistical territorial units) to which data on the number of residents are aggregated. However, this way of presentation is often insufficient for analytical purposes. The main drawbacks include the omission of natural conditions and possible modification of borders, which can statistically significantly affect the results of spatial data analyses. Since the distribution of residential households and knowledge about their spatial differentiation is needed for many areas of human activity (traffic planning, land use planning), the City of Bratislava created, for the first time, a raster visualisation of the number of dwellings, using a dataset containing grids for each individual EU country. Grid with the size of 1km x 1km has been used for Bratislava. Within the visualization, (estimated) data on the number of dwellings in apartment and family houses is shown. The number of dwellings in a family house is estimated as 1, as more specific information is not available in the source data. The source of the data for estimation is the Geodesy, Cartography and Cadastre Authority of the Slovak Republic.

Estimated number of dwellings in apartment and family houses in Bratislava (grid 1x1km)

Spatial distribution of the population is normally expressed using discrete objects (boundaries of administrative or statistical territorial units) to which data on the number of residents are aggregated. However, this way of presentation is often insufficient for analytical purposes.

Share of number of permanent population in Bratislava by sex and age group (grid 250x250m)

Spatial distribution of the population is normally processed by discrete objects (boundaries of administrative or statistical territorial units) to which data on number of population are aggregated. However, this way of presentation is often insufficient for analytical purposes. The main drawbacks include the omission of natural conditions and possible modification of borders, which can statistically significantly affect results of spatial data analyses. Since the distribution of the population is one of the basic socio-economic variables, and knowledge of its spatial differentiation is needed for many areas of human activity, the Statistical Office of the Slovak Republic created, for the first time, a raster database of the numbers of population by basic demographic structures (gender, age), using a dataset of networks containing grids for each individual EU country. For Bratislava dataset with size of 250x250 m has been used. Within visualization data (estimation) of permanent population of Bratislava by economic age groups and sex are visualized. Source of data for estimation is Ministry of interior of the Slovak republic. Shares are processed as share in every single age group on overall permanent population in grid. Within data processing, grids with small number of population has been anonymized.

The source of the data for estimation is the Ministry of Interior of the Slovak republic.

MESH model of Bratislava 2019

MESH model 2019 is a three-dimensional orthophotomap. However, instead of square pixels as in a classic raster orthophotomap, it consists of a network of polygons that create a 3D surface of objects. This results in orders of magnitude higher requirements for data capacities than in classical orthophotomaps and the subsequent geometric imperfection of the MESH model. Like the classic orthophotomap in 2D, the MESH model is a fundamental basis for 3D and 4D spatial information systems.

3D model of buildings in Bratislava

A three-dimensional model of buildings represents a spatial model of the built environment. The City of Bratislava currently has a series of 3D models showing the condition of buildings from previous years, with the latest model reaching LOD level 3 (LOD - level of detail). The 3D model of buildings is used in various areas, from different urban tasks to creating a noise map and designing measures for eliminating noise.

3D terrain model of Bratislava

A digital terrain model is a model of the earth's surface that does not contain information about any objects. It is widely used, for example as a basis for designing measures to eliminate the effects of floods from heavy rains or identifying the most suitable areas for insect spraying.
