The quality of spatial data is an important aspect for the evaluation and integration of spatial information, for example in a spatial information system. This standard was developed and provided by the International Organization for Standardization (ISO) and is part of the ISO 19xxx series for the standardization of geographic information and geodata . These quality parameters must be described by the manufacturer when new geodata is acquired.

Quality parameters

The general quality parameters for spatial data defined in the standard are:

Completeness: Presence or absence of objects, individual attributes or relationships

Logical consistency: Consistency of the conceptual, logical and physical data structure

Positional Accuracy: average positional accuracy of the individual objects

Temporal Accuracy: Correctness of the times and time relationships

Thematic Accuracy: Correctness of the attributes
