INSPIRE Reference: D2.8.III.8_v2.0(.0) TWG-PF Data Specification on Production and Measure identifier 7 (ISO 19138) Industrial Facilities 7.1.3 Logical Consistency – Topological consistency Topological consistency should be documented using Number of self intersected errors. 2011-06-15 Page LVI Name Number of self intersected errors Alternative name Loops Data quality element Logical consistency Data quality sub-element Topological consistency Data quality basic measure Error rate Definition count of all items in the data that illegally intersect with themselves Description - Evaluation scope spatial object: Site, Facility data set Reporting scope data set Parameter - Data quality value type Integer Data quality value structure - Source reference - Example Following the description, “Facility” can be related with one or more “Sites”. Sites represent the 2D geographical description of the Facility or portions of land managed by holdings. These Loops could generate misunderstandings. Measure identifier 26 7.1.4 Logical Consistency - Conceptual consistency Conceptual consistency should be documented using Number of items not compliant with the rules of the conceptual schema. Name Number of items not compliant with the rules of the conceptual schema Alternative name Loops Data quality element Logical consistency Data quality sub-element Conceptual consistency Data quality basic measure Error count Definition count of all items in the dataset that are not compliant with the rules of the conceptual schema Description The conceptual schema explicitly and implicitly describes rules which shall be followed. Violations against such rules can be, for example, the hierarchical description of entities and the geographical representation of them. Evaluation scope spatial object: Site, Facility, Plot, Installations, Buildings… data set Reporting scope data set Parameter - Data quality value type Integer Data quality value structure - Source reference - Example “Facility” should contain all the rest of entities (apart from Sites) under their perimeter. Not elements can be represented isolated.
INSPIRE Reference: D2.8.III.8_v2.0(.0) TWG-PF Data Specification on Production and Measure identifier 11 Industrial Facilities 7.1.5 Positional accuracy – Absolute or external accuracy 2011-06-15 Page Absolute or external accuracy should be documented using mean value of positional uncertainties (1D, 2D and 3D). Name Mean value of positional uncertainties Alternative name Mean value of positional uncertainties (1D, 2D and 3D) Data quality element Positional accuracy Data quality sub-element Absolute or external accuracy Data quality basic measure Error rate Definition Mean value of the positional uncertainties for a set of positions where the positional uncertainties are defined as the distance between a measured position and what is considered as the corresponding true position. Evaluation scope spatial object spatial object type: Facility Reporting scope data set Description - Parameter For a number of points (N), the measured positions are given as xmi, ymi and zmi coordinates depending on the dimension in which the position of the point is measured. A corresponding set of coordinates, xti, yti and zti, are considered to represent the true positions. The errors are calculated as 1D: ei=|xmi−xti| 2D: ei= [(xmi−xti)2+(ymi−yti)2] 3D: ei= [(xmi−xti)2+(ymi−yti)2+(zmi−zti)2] The mean positional uncertainties of the horizontal absolute or external positions are then calculated as A criterion for the establishing of correspondence should also be stated (e.g. allowing for correspondence to the closest position, correspondence on vertices or along lines). The criterion/criteria for finding the corresponding points shall be reported with the data quality evaluation result. This data quality measure is different from the standard deviation. Data quality value type measure Data quality value structure - Source reference - Example When “Facilities” (independently of the entity inside the hierarchy) are represented as single points, these are based on a “centroid” that describes the whole facility independently of the real size. This representation must be based on the criteria described on this chapter. Measure identifier 28 LVII
