Guidelines for the FAIRt publication of Terrestrial Laser Scanner Data in Geomorphic Research

Résumé

The increasing dissemination of data from Terrestrial or Permanent Laser Scanning (TLS/PLS) topographic surveys in geomorphology requires the establishment of clear recommendations for their publication. The work presented here proposes a framework to ensure that published datasets comply with the FAIRt (Findable, Accessible, Interoperable, Reusable, trustworthy) principles, with a particular attention on the documentation of the processing steps. This facilitates the evaluation of the relevance of published point clouds and their reuse. Central to this proposal is a set of structured metadata that is essential to document acquisition conditions, methodological choices and processing parameters in order to understand how the published cloud was obtained and what it can be used for. The framework presented in this article is organised into three distinct parts: the essential perimeter of publication, without which the cloud cannot be exploited, pre-processing and processing. These recommendations are accompanied by concrete examples of datasets to illustrate their implementation. To ensure the long-term interoperability of distribution, it is recommended that the LAS format be used as the standard for TLS clouds, associated with a GeoJSON file of metadata. This approach constitutes a component of a long-term preservation process, which is based on the use of open sharing and storage platforms. This standard is therefore intended to be a support tool for researchers, structuring publication practices while remaining open to adapt to future technological and scientific developments. Designed for TLS acquisitions, it could be extended to photogrammetric point clouds if specific photogrammetric processing information is provided.
