19、 PD ISO/TS 19163-1:2016 ISO/TS 19163-1:2016(E) Introduction Geographic imagery and gridded thematic data are widely used in the geospatial community and related fields. A preliminary work item on imagery and gridded data components, carried out by ISO/TC 211 in 1999 to 2000, provides a summary of th

20、e conceptual classification of gridded data based on spatial and attribute properties and identifies five basic components of imagery and gridded data (ISO/TC 211 N 1017). ISO/TS 19101-2, ISO 19123 and ISO/TS 19129 specify domains and ranges of imagery, grids and coverages, and their associated rela

21、tionships. ISO/TS 19129 breaks down the metadata into discovery, structural, acquisition and quality metadata. However, there are no detailed descriptions on each category and no clear associations with metadata defined in ISO 19115:2003, ISO 19115-2, ISO/TS 19130 and ISO/TS 19130-2. Imagery is acqu

22、ired by remote sensors directly or derived from source imagery. Value-added image processing can be used to derive physical properties of a remote object from images (ISO/TS 19101-2). Besides the derived images, imagery can also be integrated with other data sources to produce new gridded coverage d

23、ata for a specific theme, called thematic data, which is widely used in various applications. However, the characteristics of thematic data are not covered by the existing International Standards and Technical Specifications noted above. ISO/TS 19130 identifies the type of remote sensors by the meas

24、urand of the sensor, e.g. optical radiation, microwave energy and SONAR (acoustic) energy. Images acquired by optical sensors have different appearances and characteristics compared with those by a microwave sensor, e.g. SAR data. The framework defined in ISO/TS 19129 describes imagery, gridded and

25、coverage data at multiple levels, including an abstract level, a content model level and an encoding level. The first two levels combine a number of well-defined content structures in accordance with ISO 19123 and define the contents of continuous quadrilateral gridded coverages with grids of both c

26、onstant and variable cell sizes. However, the content model level does not specify the necessary metadata for common understanding when integrating datasets encoded in different formats. At the encoding level, ISO/TS 19129 does not provide the explicit encoding rules for mapping content model to mac

27、hine-independent encoding structure, which is crucial for the mapping and translation of images in different formats without losing information. Based on the frameworks defined in ISO/TS 19101-2 and ISO 19123, this Technical Specification specifies the categories of imagery and gridded data and esta

28、blishes a corresponding hierarchical content model. Categories of imagery and gridded data are defined based on thematic and spatial attributes and sensor types. The content model is then defined to describe the required content components of each category, including the spatial and attribute struct

29、ures and the critical metadata entries as well. These metadata entries are specified as the minimum required metadata information for the purpose of common understanding. Traditionally, remote sensing data products generally have a header part and a data part. This Technical Specification describes

30、the minimum content requirements for the header part. For ease of implementation, this Technical Specification defines encoding rules to map the content models to XML-based encodings, following the general encoding rules defined in ISO 19118 and the encoding rules for UML-to-GML application schema d

31、efined in ISO 19136:2007, Annex E. Since GMLCOV schema (OGC 09-146r2) is optimized for handling coverages, the coverage component of the schema can be based on GMLCOV. An increasingly large volume of image and gridded data, both natural and synthetic, is being produced because more remote sensors ar

32、e becoming available. These data are encoded in diverse formats, such as GeoTIFF, BIIF, HDF-EOS, JPEG 2000, NetCDF and others as described in ISO/TR 19121. These encoding formats follow different data models, preventing them from being interoperable. In order to encode the contents defined in this T

33、echnical Specification into these data formats, ISO 19163 has been split into multiple parts with this Technical Specification defining the content components and general encoding rules and the subsequent parts defining the binding between the contents and individual physical data formats. ISO 2016

34、All rights reserved v PD ISO/TS 19163-1:2016 Geographic information Content components and encoding rules for imagery and gridded data Part 1: Content model 1 Scope This Technical Specification classifies imagery and regularly spaced gridded thematic data into types based on attribute property, sens

35、or type and spatial property, and defines an encoding-neutral content model for the required components for each type of data. It also specifies logical data structures and the rules for encoding the content components in the structures. The binding between the content and a specific encoding format

36、 will be defined in the subsequent parts of ISO 19163. This Technical Specification does not address LiDAR, SONAR data and ungeoreferenced gridded data. The logical data structures and the rules for encoding the content components will be addressed in the subsequent parts of ISO 19163. 2 Conformance

37、 This Technical Specification standardizes the categories of imagery and regularly spaced gridded thematic data as well as their core content models. There is one conformance class for each data category. Any set of imagery and regularly spaced gridded thematic data claiming conformance to this Tech

38、nical Specification shall satisfy the corresponding requirements defined in the abstract test suite in Annex A. 3 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
