Scalable space-time density data fusion

A computer-implemented method of operating a database system to generate a query result, the method comprising:

• assigning, via a file formatting sub-system including an electronic hardware controller, coordinate values corresponding to a first data format (raster) to data objects included in an initial data set having a second data format (vector) different from the first data format;
• generating a dual-format data file, using the file formatting sub-system, that correlates the data objects having the second data format with the coordinate values corresponding to the first data format to generate a dual-format data file;
• storing, in a data storage unit, the dual-format data file;
• receiving a query for at least one data object included in the initial data set, the at least one data object having the second data format;
• identifying at least one dual-format data file that includes the at least one data object having the second data format from a plurality of dual-data files stored in the data storage unit;
• and
• outputting the at least one data object based on the corresponding coordinate values stored in the at least one dual-format data file.

A computer-implemented method of operating a database system to generate a query result, the method comprising:

• overlaying a plurality of raster grid cells on an initial vector data set using a processing sub-system including an electronic hardware controller, each raster grid cell having assigned thereto a set of grid coordinates;
• generating, via a file formatting sub-system implemented with an electronic hardware controller, a fused data file including both a selected set of grid coordinates corresponding to at least one raster grid cell that overlays a vector object included in the vector data set, and object identification information identifying the vector object;
• receiving a query for at least one target vector object included in the vector data set;
• performing, via a processing sub-system including an electronic hardware controller, an image recognition operation that determines a reference vector object based on the target vector object, and determines at least one set of grid coordinates corresponding to the vector object based on a comparison between the reference vector object and the plurality of grid cells;
• and
• outputting the object identification information from the fused data file that stores the selected set of grid coordinates.

• generating, via a processing sub-system including an electronic hardware controller, a grid system including a plurality of grid cells, and overlaying, the grid cells on an initial data set having a first data format, each grid cell representing data having a second data format and having assigned thereto a set of grid coordinates;
• assigning, via a file formatting sub-system including an electronic hardware controller, coordinate values corresponding to the second data format to data objects included in an initial data set having the first data format;
• storing, in a dual-format data file, identification information of a selected data object having the first format with a selected set of coordinates corresponding to a selected grid cell that overlies the selected data object;
• receiving a query for at least one target data object having the second data format, and generating a reference data object having the first data format based on the query;
• and
• outputting the at least one target data object having the second data format based on a comparison between the reference data object and the plurality of grid cells.
