AUTOMATED IDENTIFICATION OF ANOMALOUS MAP DATA

摘要

An autocheck module of a map system is configured to automatically identify anomalous conditions within map data that may indicate an error within the data. The identification of the anomalous conditions is accomplished by application of different autocheck types to the map data, each autocheck type representing a class of anomalies and being triggered if particular map data exhibits the anomalous condition associated with the autocheck type. In one embodiment, for at least some of the portions of map data that trigger an autocheck type, an issue entry is created in an issue database, the issue entry referencing the autocheck type that was triggered, the map data that triggered it, and any associated data of relevance for the particular autocheck type in question.

1. A computer-implemented method of identifying anomalous conditions in a database of map data, the method comprising:
storing a set of distinct autocheck types, each autocheck type associated with a category of anomalous condition and indicating, when applied to a portion of map data, whether the associated category of anomalous condition is present within the portion; automatically applying a plurality of the stored autocheck types to the database of map data; and for each applied autocheck type, and for portions of the map data for which the autocheck type indicates that the associated category of anomalous condition is present, creating an issue entry within an issue database that references the autocheck type and the portion of the map data within which the associated anomalous condition is present.
