Data from : A long-term dataset of topography and nearshore bathymetry at the macrotidal pocket beach of Porsmilin, France
The archived multi-sensor dataset detailed here presents the results of topographic and bathymetric surveys at Porsmilin, a macrotidal pocket (embayed) beach situated in Brittany, in northwest France. The Porsmilin beach survey program was launched in January 2003 by the Institut Universitaire Européen de la Mer (IUEM/Univ. Brest) and is continuing today in the framework of the French coastal observation service SNO-DYNALIT. The dataset contains over 16 years of beach profile surveys and a large collection of recurring high-resolution subtidal and subaerial digital elevation models (DEMs) obtained using various survey methods. The dataset is accompanied by time-series of inshore waves and water levels, and enriched metadata, that will facilitate its future reuse in coastal research.
The dataset is structured as follows, with separate metadata (child records) for 1) beach profiles, 2) topographic DEMs, 3) bathymetric DEMs, 4) fusion DEMs, 5) orthophotos, 6) inshore waves and 7) astronomical tides.

- Statement
-
For allowing topographic surveys using RTK-GNSS (real-time kinematic global navigation satellite system), including data georeferencing and verification, geodetic survey marks (cast metal disks) were installed on stable ground (e.g., bedrock reef and human structures). The arrangement of survey marks evolved over the course of the monitoring program but it typically included one survey mark used as GNSS base station and a minimum of two for data verification. Fixed coordinates for the base station were obtained using long-static averaging with a tripod (~240 min), over several periods of time, and were post-processed in comparison with two nearby IGN GNSS stations. Topographic surveys are generally carried out during spring low tides to increase survey coverage.
- Description
-
Coordinates used for the dataset are metric and referenced to the legal coordinate systems for metropolitan France, i.e., RGF93-Lambert 93 horizontal and NGF-IGN69 vertical (EPSG:5698). Elevation zero (m-NGF) corresponds to approximately 0.5 m below mean sea level (MSL).

- Description
-
Codes for browsing through the database and plotting selected survey products are made available with the dataset. Code is written in MATLAB (R2018b). Although MATLAB is a proprietary language, the .m files can be read with a text viewer.
