前面打“√”的为已完成阶段 | | 范 围 | To standardise concepts for the description and representation of imagery and gridded data in the context of the ISO 15046 suite of standards. This includes new work on the following aspects of such data: Rules for application schemas, Quality principles and Quality evaluation procedures, Spatial reference systems, Visualisation, and Exploitation services. The work will also identify aspects of existing parts of the family of standards that need to be expanded to address imagery and gridded data. New metadata elements will be defined using the extension mechanism of ISO 15046-15. Methods of encoding imagery and gridded data will be identified for inclusion in ISO 15046-18 | | 目 的 | ISO/TC 211, in Resolution 38, has recognised the importance of raster and matrix data in the field of geographic information / geomatics. As a result of this resolution a draft Technical Report 16569 was developed which identifies the existing work on Imagery and gridded data that is ongoing in ISO and external technical organisations. This report also outlined a plan for adding Imagery and gridded data to the suite of ISO 15046 standards. ISO/TC 211, in Resolution 81, indicated that the most appropriate way of handling the recommendations presented in draft Technical Report 16569 is to begin the work on Imagery and gridded data in a new standard at the preparatory Stage 0. In addition a related new work item on Coverages is to be developed which takes into account draft Technical Report 16569. The initial emphasis is to be on imagery (both synthetic and natural), and gridded data such as digital elevation models. This project will be conducted in cooperation with the Open GIS Consortium (OGC). Part 6 of the OGC Abstract Specification: The Coverage Type and its Subtypes (OGC 98-106R2) will be used as the base document. Work can begin immediately; completion will be necessary to support the final development of other geographic information standards. | | 其 它 | 立项时间：1999年3月 立项文件：N 617 N 699 |
