Export formats

  • GRDC Export format (ASCII text),

    line-based text format especially developed to share GRDC discharge data, and associated metadata. It provides a series of time-value-pairs. The header of file provides observation metadata like station, water body, co-ordinates, upstream catchment size, etc. as well as time-series metadata and provenance information.

  • GRDC Statistics format (CSV text),

    line-based, text format especially developed to share GRDC primary statistics data, and associated metadata. Statistical values of the same type like yearly values, long-term values or seasonal values are compiled in one file. The header of file provides observation metadata like station, water body, co-ordinates, upstream catchment size, etc. as well as processing information.

  • WaterML2 format (XML),

    standard exchange format for hydrological time-series. Times series are provided as time-value-pairs, along with observation and time series metadata. A brief summary of WaterML2 is given at: http://waterml2.org/ .

    Please note: WaterML2 format is primarily developed for automatic processing, for example with Python, and not for viewing. However, you can open a wml2 file in your browser or use an XML-editor to examine your wml2 data.

  • ZRXP exchange format (ASCII text),

    line-oriented text format used particularly for data exchange between WISKI systems. It provides a series of time-value-pairs and encrypyted data quality information. The corresponding column definition and time-series information is in the file header.

  • Catchment polygons are provided as GeoJSON files, an open standard format to share geographic features. GeoJSON is supported by various mapping and GIS software products as well as open source mapping tools. Please note, that catchment polygons do not exist for all GRDC stations particularly for those which came to the GRDC dataset after 2011, when majority of polygons were delineated.
