Trustworthy, reproducible and open science requires the digital availability of well-documented, findable, accessible, interoperable and reusable data. Due to the high relevance of geodetic data beyond the geodesy (e.g., in geophysics, hydrology, oceanography, glaciology and climatology), it is essential to provide them in citable form that allow the provision of proper credit and attribution for the data producers and their institutions.
The assignment of digital object identifier (DOI) can provide such credit and additionally support data discovery in the internet. The registration of a DOI requires the provision of at least a minimum set of descriptive metadata in machine-readable form (following international standards) that complements disciplinary, contextual metadata and documentation. The objects assigned with DOIs are persistently archived at research data repositories and are fully citable in scholarly literature.
Since 2019, the GGOS Committee on DOIs for geodetic data is developing recommendations and guidance for the consistent use of DOIs for geodetic data across all services of the International Association for Geodesy (IAG). While the first version of metadata recommendation was developed for GNSS data, many general remarks are valid for data from other techniques.
Once the DOIs are registered, it is important to ensure that the data assigned with DOI are properly cited. This is an especially large challenge for geodetic data due to their high granularity and international character. It is common practice to provide data products representing different processing levels (e.g., ultra-rapid, rapid, final products) or products representing different levels of aggregation (e.g., solutions measured by stations are combined by regional analyses centers, the latter are later combined to one global best-fit solution that represents the final solution for one geodetic service). Only the citation of each object contributes to a combination product ensures that credit is given to all researchers and institutions involved. The challenge has different facets of which the technical implementation seems to be the smallest (the DataCite Metadata Schema has dedicated metadata properties to make digital connection between data, software and scholarly literature). Larger challenges lie in the practical citation of hundreds of DOIs in research articles (most journals do not accept it) or data publications and the more educational task to enable researchers to properly cite the data they used.
