Remote sensing products derived from radar satellite data are developed for global monitoring of the hydrosphere. Depending on the instrument, for example Synthetic Aperture Radar (SAR) or Scatterometer (SCAT), the recorded data shows diverse characteristics which enables a great number of applications. With the launch of new satellites with advanced instruments (e.g. Sentinel 1, foreseen launch date around 2013), this range of applications is expected to be extended. Further, existing processing algorithms may have to be adapted or even new algorithms may have to be developed to process the new data. Hence, the interplay of data retrieval and data processing is a steady dynamic process. During the processing from low level- (level 1, raw data) to high level products (level 2, level 3; geophysical products regularly sampled in space and time), various software packages and auxiliary data may be used.
Information about the products characteristics (from acquisition to processing), called metadata, serves as an important source of information for both developers and third-party users. The International Organization for Standardization (ISO) provides metadata standards for describing geographic information. Within the European Union (EU), another important guideline for describing spatial data is the directive for the creation of a geodata-infrastructure in the European Community, called INSPIRE (Infrastructure for Spatial Information in Europe).
The objective of this master thesis is to investigate methods for managing products and the corresponding metadata, and to provide this information for third party users, taking into account the mentioned standards for geographic metadata. The approach is based upon implementing standard compliant XML files, and the design of a relational database for the purpose of metadata storage and management.
