Method and system for accessing spatially organized geographic data in blocks
First Claim
1. A method of providing geographic data comprising:
- providing geographic data for use on a plurality of different computing platforms, wherein the geographic data are organized into parcels having a parcel data size;
selecting a parcel block data size for one of said platforms, wherein said parcel block data size is larger than said parcel data size; and
obtaining blocks of parcels together as groups, each of said blocks has a data size not exceeding said parcel block data size.

Abstract
A method whereby a computing platform that uses geographic data that are spatially organized into parcels of a given size can specify a parcel block size larger than the given size. Thereafter, during runtime, the geographic data are accessed by the computing platform in groups of one or more parcels not larger than the parcel block size. According to one embodiment, at or after initialization of the computing platform, groupings of parcels corresponding to parcel blocks are determined. Each parcel block has a size larger than the maximum parcel size but not larger than a maximum parcel block size. Data identifying the groupings and the parcels corresponding thereto are stored on the computing platform and the data identifying the groupings and the parcels corresponding thereto are used to access all the parcels corresponding to a parcel block whenever geographic data in any one of the parcels are needed.
