The Open Geospatial Consortium (OGC) is excited to announce the formation of the OGC GeoZarr Standards Working Group (SWG). The new SWG will develop a Zarr encoding for geospatial gridded data in the form of Zarr conventions.<\/p>\n\n\n\n

Zarr is a cloud-native data format for n-dimensional arrays that enables access to data in compressed chunks of the original array. Zarr facilitates portability and interoperability on both object stores and hard disks. <\/p>\n\n\n\n

As a generic data format, Zarr has increasingly become popular to use for geospatial purposes. As such, in June 2022, OGC endorsed Zarr V2.0<\/a> as an OGC Community Standard<\/a>. The purpose of the GeoZarr SWG is to have an explicitly geospatial Zarr Standard (GeoZarr) adopted by OGC that establishes flexible and inclusive conventions for the Zarr cloud-native format that meet the broad requirements of the geospatial domain. These conventions aim to provide a clear and standardized framework for organizing and describing data that ensures unambiguous representation.<\/p>\n\n\n\n

The objectives of GeoZarr conventions include:<\/p>\n\n\n\n

    \n
  1. Compatibility: Ensuring easy compatibility with popular mapping and data analysis tools such as GDAL, Xarray, ArcGIS, QGIS, and other visualization tools, enabling seamless integration into existing workflows.<\/li>\n\n\n\n
  2. Dimensions: Supporting multi-dimensional data, such as hyperspectral and altitude information, to address broad geospatial data requirements.<\/li>\n\n\n\n
  3. Data Discovery: Providing metadata for discovering, accessing, and retrieving the data, including composite products made of multiple data arrays.<\/li>\n\n\n\n
  4. Mixing Data: Facilitating the combination of different types of geospatial data, including satellite images, elevation maps, and weather models, to create comprehensive and informative datasets.<\/li>\n\n\n\n
  5. Flexibility: Allowing scientists and researchers to work with heterogeneous data types and projections in their preferred software and programming languages, promoting flexibility and adaptability in geospatial data processing and analysis.<\/li>\n<\/ol>\n\n\n\n

    In addition to the encoding of geospatial data and metadata, the GeoZarr Standard will provide a multi-dimensional alternative to the two-dimensional Cloud-Optimized GeoTiff format (COG – adopted by OGC in May 2023)<\/a>, which has lately gained popularity due to its serverless capabilities. These capabilities will allow for inherent support of traditionally server-based functions, such as visualization (similar to OGC API – Maps<\/a>), data subset access (analogous to OGC API – Coverages<\/a>), and symbology (equivalent to OGC API – Styles<\/a>). These aspects are planned to be incorporated as optional profiles (e.g. conformance classes).<\/p>\n\n\n\n
