Computer implemented methods and systems for multi-level geographic query

A system for creating point of interest indices for a map with a plurality of spatial levels, the system comprising:

• a storage device that stores a set of instructions;
• and
• at least one processor configured to execute the set of instructions in order to:
• receive documents from one or more computerized data systems, the documents corresponding to one or more points of interest (POIs) and a location of the one or more POIs;
• determine at least one spatial level for a footprint of the one or more POIs;
• define at least one POI footprint based on a spatial identifier for each POI at each determined spatial level;
• and
• create at least one index based on at least one defined POI footprint, each index comprising at least one POI spatial identifier corresponding to a determined spatial level,
• wherein the at least one spatial level is determined based on a significance of at least one document, the significance of the at least one document reflecting the type of POIs associated with the at least one document, and
• wherein the number of determined spatial levels for each document is based on the respective significance of each document.

A non-transitory computer-readable storage medium storing a computer program for processing queries for points of interest (POIs) using a map structure with multiple levels, the computer program configured to cause at least one computer processor to:

• receive documents from one or more computerized data systems, the documents corresponding to one or more points of interest (POIs) and a location of the one or more POIs;
• determine at least one spatial level for a footprint of the one or more POIs;
• define at least one POI footprint based on a spatial identifier for each POI at each determined spatial level;
• and
• create at least one index based on at least one defined POI footprint, each index comprising at least one POI spatial identifier corresponding to a determined spatial level,
• wherein the at least one spatial level is determined based on a significance of at least one document, the significance of the at least one document reflecting the type of POIs associated with the at least one document, and
• wherein the number of determined spatial levels for each document is based on the respective significance of each document.
