Method for computer-aided processing of positional information of measurement data, comprising the steps: - providing measurement data in a first table by means of an input unit, whereby the first table comprises measurement data coordinates (x,y), which are defined in a two-dimensional coordinate system, and an identifier for each measurement data point, - providing a two-dimensional map tile of a map by means of an input unit, whereby the map tile comprises a fixed number of pixels, which represent a two-dimensional coordinate range at a given zoom-level (z) and for a given coordinate projection, - whereby a pixel identification number is assigned to each pixel of the map tile, and - whereby a tile identification number is assigned to the map tile, and - each position in the map tile is defined by two-dimensional coordinates (x,y) in the two-dimensional coordinate system, thereby the two-dimensional coordinates are linked to a pixel identification number, - determining the pixel identification numbers corresponding to the measurement data coordinates (x,y) which are within the two-dimensional coordinate range of the map tile by means of a determining unit, - storing the identifier, the pixel identification number, the tile identification number, and the given zoom-level (z) for each of the measurement data points, which are within the two-dimensional coordinate range of the map tile, in a second table by means of a storage unit, and - localizing a position of a measurement data point on the map tile by means of a localization unit retrieving the pixel identification number from the second table. - providing measurement data in a first table by means of an input unit, whereby the first table comprises measurement data coordinates (x,y), which are defined in a two-dimensional coordinate system, and an identifier for each measurement data point, - providing a two-dimensional map tile of a map by means of an input unit, whereby the map tile comprises a fixed number of pixels, which represent a two-dimensional coordinate range at a given zoom-level (z) and for a given coordinate projection, - whereby a pixel identification number is assigned to each pixel of the map tile, and - whereby a tile identification number is assigned to the map tile, and - each position in the map tile is defined by two-dimensional coordinates (x,y) in the two-dimensional coordinate system, thereby the two-dimensional coordinates are linked to a pixel identification number, - whereby a pixel identification number is assigned to each pixel of the map tile, and - whereby a tile identification number is assigned to the map tile, and - each position in the map tile is defined by two-dimensional coordinates (x,y) in the two-dimensional coordinate system, thereby the two-dimensional coordinates are linked to a pixel identification number, - determining the pixel identification numbers corresponding to the measurement data coordinates (x,y) which are within the two-dimensional coordinate range of the map tile by means of a determining unit, - storing the identifier, the pixel identification number, the tile identification number, and the given zoom-level (z) for each of the measurement data points, which are within the two-dimensional coordinate range of the map tile, in a second table by means of a storage unit, and - localizing a position of a measurement data point on the map tile by means of a localization unit retrieving the pixel identification number from the second table.
