With a total of 2 patents, his work focuses on enhancing the performance of spatial queries and generating geometric models for massive datasets.

Latest Patents

One of his latest patents is titled "Hierarchical grid for spatial querying." This invention provides techniques for improving the performance of spatial queries by defining a grid that divides the domain space into cells. It utilizes a cell-to-item mapping to determine which items do not need to be individually evaluated against the location criteria of the spatial queries. Based on the cell to which an item belongs, it may automatically qualify as a match, be disqualified, or require item-specific evaluation. To accommodate items of varying sizes, the query window of a spatial query may be expanded, and multiple grids with differently sized cells can be established for the domain space.

Another notable patent is "Geometric model for visually debugging massive spatial datasets." This invention involves generating geometric models from raw datasets. The method includes receiving a raw data set and utilizing generation parameters such as an abstraction function and a plurality of size pairs. Each size pair consists of a view size and a portion size, which are used to associate grid square sizes with the size pairs. The resulting geometric models are based on the raw data set, the plurality of size pairs, and the associated grid square sizes.
