INSPIRE Reference: D2.8.III.8_v2.0(.0) TWG-PF Data Specification on Production and Industrial Facilities 2011-06-15 Page LXXVIII 1.2.1 Namespace The first point is to define a convenient namespace. To ensure both uniqueness within the INSPIRE context and possible link with download services, it may be useful to add to the mandatory country code, the data provider name or acronym. For instance, namespace might be: NL.ProductionAndIndustrialSite 1.2.2 Local identifier The second point is to decide on the local identifier to be used. Of course, to ensure the required characteristics, this local identifier must be unique (in the local/national set of ProductionAndIndustrial data), persistent, and must include only the limited set of characters allowed by the Generic Conceptual Model. 1.3 Estimated accuracy For INSPIRE, ProductionAndIndustrial data shall be published in the Coordinate Reference System mandated by the Implementing Rule on Reference Systems, i.e. in ETRS89 for areas on the Eurasian tectonic plate and in ITRS elsewhere. Of course, INSPIRE users will be interested by having information about the accuracy of ProductionAndIndustrial data, as they receive them, in the Coordinate Reference System mandated by INSPIRE. It is why the clauses about application schema and about quality and metadata require cadastral data providers to give estimated accuracy related to the coordinates in ETRS89 (or ITRS). However, in most Member States, the estimated accuracy is generally known in the source Coordinate Reference System, the national or local one. The estimated accuracy for INSPIRE will be the combination of estimated accuracy in original Coordinate Reference System and of the accuracy of the coordinate transformation between original Reference System to INSPIRE Reference System. Coordinate transformation between two horizontal geodetic datum is generally done, using one of the three following methods: − transformation with 3 parameters − transformation with 7 parameters − transformation with a grid. Experience in some countries has shown that transformation with 3 or even 7 parameters might bring deviations up to 10 metres. So, the impact of such transformations may not be neglected on cadastral data whose original accuracy generally varies from some decimetres to some metres. The ideal solution would be for each Member State to define good quality coordinate transformations (using grids and bringing no deviation bigger than some centimetres). However, if not possible before the deadlines of INSPIRE, the impact of coordinate transformation has to be taken into account when giving information about positional accuracy, both in the application schema and in metadata. 11 Portrayal This clause defines the rules for layers and styles to be used for portrayal of the spatial object types defined for this theme.
INSPIRE Reference: D2.8.III.8_v2.0(.0) TWG-PF Data Specification on Production and Industrial Facilities 2011-06-15 Page LXXIX In section 0, the types of layers are defined that are to be used for the portrayal of the spatial object types defined in this specification. A view service may offer several layers of the same type, one for each dataset that it offers on a specific topic. Section 11.4 specifies the styles that shall be supported by INSPIRE view services for each of these layer types. In section 11.5, further styles can be specified that represent examples of styles typically used in a thematic domain. It is recommended that also these styles should be supported by INSPIRE view services, where applicable. Where XML fragments are used in these sections, the following namespace prefixes apply: • sld="http://www.opengis.net/sld" (WMS/SLD 1.1) • se="http://www.opengis.net/se" (SE 1.1) • ogc="http://www.opengis.net/ogc" (FE 1.1) IR Requirement 15 If an INSPIRE view services supports the portrayal of data related to the theme Production and Industrial Facilities, it shall provide layers of the types specified in this section. DS Requirement 4 If an INSPIRE view network service supports the portrayal of spatial data sets corresponding to the spatial data theme Production and Industrial Facilities, it shall support the styles specified in section 11.4. If no user-defined style is specified in a portrayal request for a specific layer to an INSPIRE view service, the default style specified in section 11.4 for that layer shall be used. Recommendation 11 In addition to the styles defined in section 11.4, it is recommended that, where applicable, INSPIRE view services also support the styles defined in section 11.5.
