Patent ID: 8504393

Claim:
A method for providing a requested insurance rate using a programmed computer system including a processor and a non-transitory, tangible computer readable medium communicatively coupled to the processor and storing instructions executable by the processor to perform the method comprising: storing in a database existing data associated with a plurality of coordinate grid blocks, each coordinate grid block comprising a four-sided area defined by truncated latitude and longitude values of a coordinate grid system, wherein the number of digits in the truncated latitude and longitude values that define each coordinate grid block defines the geographic size of that coordinate grid block; the processor receiving an insurance rate query from a user via a user interface regarding a particular location having a coordinate pair comprising a non-truncated longitude value and a non-truncated latitude value of the particular location; the processor determining a target coordinate grid that encompasses the coordinate pair by identifying a coordinate grid block having truncated latitude and longitude values that correspond to the non-truncated longitude and latitude values of the coordinate pair of the particular location; the processor querying a database for a target set of existing data associated with the determined target coordinate grid block, wherein the existing data was associated with the target coordinate grid block prior to receiving the coordinate pair; the processor querying the database for supplemental existing data associated with coordinate grid blocks proximate the determined target coordinate grid block, including: setting an index value to an initial value, the index value associated with a first ring of coordinate grid blocks, wherein the current ring of coordinate grid blocks surrounds the target coordinate grid block associated with the coordinate pair; performing a first query of the database for supplemental existing data associated with the first ring of coordinate grid blocks; automatically determining that the quantity of the retrieved target set of data and the retrieved supplemental existing data is below a threshold level is below a threshold level, and in response to such determination, incrementing the index value; and performing a second query of the database to retrieve supplemental existing data associated with a second ring of coordinate grid blocks associated with the incremented index value, the second ring of coordinate grid blocks being larger than the first ring of coordinate grid blocks; the processor calculating an insurance rate based at least in part on the retrieved target set of existing data and the retrieved supplemental existing data; and the processor communicating the calculated insurance rate to the user.
