This data publication presents the anonymized original answers of the ICGEM user survey “Analysis and Future Plans with the SAMDAT Project”. In total, 112 respondents completed the survey. Data collection started on the 1st of September and ended on the 31st of October 2024. The survey was announced on the ICGEM website, and the questionnaire was integrated directly into the website. A separate page was developed explaining the survey purpose. Respondents were contacted via the ICGEM users mailing list, the geodesy mailing list, and LinkedIn. Responses were collected anonymously from the beginning.

The objective of the survey is twofold: firstly, to ascertain the current user experience with the portal and, secondly, to identify potential areas for improvement of the service. The analysis identifies various user groups in order to find out how ICGEM can best serve the needs of a diverse range of geoscientific applications. It is crucial to comprehend user expectations, since ICGEM is dedicated to demand-driven development. Furthermore, the survey offers users the chance to indicate their priorities for planned features and extensions of the ICGEM platform within the SAMDAT project.

The associated report (Torhov et al., 2025) presents the analyses of user feedback gathered from the global user community of the ICGEM Service (International Centre for Global Earth Models). ICGEM serves as a pivotal resource for gravity field modelling, serves as primary resource for global gravitational models and offers an array of interactive tools. Through the recently launched SAMDAT project, ICGEM continues to improve it service and web presentation. New gravity field functionals, datasets and improved metadata are planned to be introduced in alignment with community needs. This user survey was an important first step to collect feedback on the current and upcoming service portfolio of ICGEM. Survey data was collected through a questionnaire to assess scientific applications, uncover feature expectations, and identify opportunities for improvement. The results confirm ongoing project activities and set new directions such as in data representation, documentation and outreach.
