Embodiments of a method for creating a graph database which is arranged to store data in the form of graph tuples comprising n-parts, are described. In an embodiment, each tuple-part is encoded into a unique part identifier (UPI). A geospatial UPI is defined for two-dimensional data elements that include a plurality of data points defined by respective pairs of an X-ordinate and a Y-ordinate. A two-dimensional data space is divided into a plurality of uniform Y strips of defined widths. The Y-strip width is selected to correspond approximately to an anticipated Y dimension of a typical search region of interest. The geospatial UPI encodes a plurality of coordinate points in a two -dimensional data space into a single datum that includes respective pairs of an X-ordinate and a Y-ordinate. The geospatial UPI comprises a data structure arranged in order of sort priority by the geospatial UPI type code, geospatial subtype, and Y-strip identifier followed by the X-ordinate data and Y-ordinate data. The component fields of the data structure are arranged so that the datum can be sorted linearly as a single unsigned integer, thus facilitating a search over a two dimensional region of the data by allowing a search process to linearly scan a limited identifiable region of each of the several strips overlapping the search region of interest.
