Geospatial object property assessment apparatus, assessment system, editor apparatus and method of assessing property of a geospatial object

摘要

A geospatial object property assessment apparatus comprises a processing resource (102) arranged to support a geospatial object property processor (206) comprising a subject data source input (212) capable of receiving a first metadata associated with 10 quality of current source information content used to define a property (408) of a geospatial object; a resource data source input (214) capable of receiving a second metadata associated with quality of candidate resource information content for updating the definition of the property (408) of the geospatial object. The apparatus also comprises an assessment processor (208) operably coupled to the inputs (212, 214), the 15 assessment processor (208) being arranged to use the first metadata and the second metadata in accordance with a predetermined ruleset in order to determine whether the candidate resource information content constitutes a qualitatively better resource to define the property of the geospatial object than the current source information content.

1. A geospatial object property assessment apparatus, the apparatus comprising:
a geospatial object property processor, the geospatial object property processor including: a subject data source input capable of receiving a first metadata associated with quality of current source information content used to define a property of a geospatial object; a resource data source input capable of receiving a second metadata associated with quality of candidate resource information content for updating the definition of the property of the geospatial object; an assessment processor operably coupled to the subject data source input and the resource data source input, the assessment processor being arranged to use the first metadata and the second metadata in accordance with a predetermined ruleset in order to determine whether the candidate resource information content constitutes a qualitatively better resource to define the property of the geospatial object than the current source information content, wherein the assessment processor is arranged to calculate a first score using the first metadata and calculate a second score using the second metadata, and wherein the assessment processor is further arranged use the first score and the second score in accordance with the predetermined ruleset in order to determine whether the candidate resource information content constitutes the qualitatively better resource to define the property of the geospatial object than the current source information content; and an alert generator, the alert generator being arranged to generate a first alert in response to the determination by the assessment processor that the candidate resource information constitutes the qualitatively better resource to use to define the property of the geospatial object than the current source information content.
