Introduction
Standard Overview
QX/T 237-2014 specifies the types and description methods of the core metadata of the Fengyun polar-orbiting series of meteorological satellites, and is applicable to the full life cycle management of satellite datasets. The standard is formulated with reference to GB/T 19710-2005 "Geographic Information Metadata", and contains 8 normative appendices and 12 code tables.
Core metadata types
| Metadata subset | English abbreviation | Required | Main content |
|---|---|---|---|
| Metadata entity information | MD_Metadata | Required | Identifier, language, creation date, etc. |
| Data resource identification | MD_Identification | Required | Satellite name, observation instrument, orbital parameters |
| Data quality | DQ_DataQuality | Optional | Quality level, abnormal event record |
| Reference system | RS_ReferenceSystem | Optional | Coordinate system, projection method |
Key technical elements
Satellite observation instrument codes
Appendix B.4 of the standard defines the abbreviations of 19 observation instruments carried by the FY-3 satellite, such as:
- MWTS: Microwave thermometer
- IRAS: Infrared spectrometer
- SEM: Space environment monitor
Data quality grading
Quantitative evaluation is achieved through the dqGrade element, and the processing process of abnormal events needs to be recorded in the lineage element.
Implementation Suggestions
Metadata Description Specifications
1. FY-3D satellite data should fully fill in the orbit parameter entity (MD_orbParm), including:
- semiMajorAxis
- orbital inclination
- ascension
2. Archival information should indicate the media type (tape/disk) and retention period
Standard Evolution Analysis
Compared with the 2005 version, the 2014 version adds:
- Accuracy requirements for satellite altitude (satHeight)
- Data dump record (translationRecord) field
- Ultraviolet ozone detector (SBUS) and other new equipment coding
