CoastSeg: Beach transects and beachface slope database v2.0
Coastal shoreline-normal transects, to support shoreline extraction from satellite imagery, and tidal correction of CoastSeg-derived shoreline time-series and other shoreline data, as well as miscellaneous analyses of coastal shoreline data.
These data work with the software package CoastSeg https://github.com/SatelliteShorelines/CoastSeg. More details are available on the project's website https://satelliteshorelines.github.io/CoastSeg/
These transecst are not comprehensive in coverage, representing the best available data known to us at this time, and are provided to the user as a courtesy, but each user has the option (and is encouraged) to develop and use their own transects.
Transects data
1. id: unique ID code
2. slope: beach face slope, for tidal correction of transect-based data3. distance: distance in degrees between slope datum location and transect location4. feature_x: transect location x5. feature_y: transect location y6. nearest_x: nearest slope location x7. nearest_y: nearest slope location y
Note that beach slopes are not available for every transect location. A value of NULL is used in those (relatively rare) locations.
Beach face slope and transect data have been derived from:
