Updates for Navigational Map Data Organized in Lists

摘要

A geographic database may include binary data including list portions and/or non-list portions. A computing device may identify a list in a first binary large object (BLOB) for navigation data including road segments and road attributes. The first BLOB is segmented based on the byte list portion into a plurality of elements each having a predetermined size. The computing device may define a series of operations for the multiple elements to transform the first BLOB to a second BLOB.

1. A method comprising:
identifying, using a processor, a list portion in a first binary large object (BLOB) for navigation data including road segments, road attributes, or map polygons; segmenting, in response to the list portion, the first BLOB into a plurality of elements each having a predetermined size; and defining a series of operations for the plurality of elements to transform the first BLOB to a second BLOB.
