CoastSeg: Beach transects and beachface slope database v2.0

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 data
3. distance: distance in degrees between slope datum location and transect location
4. feature_x: transect location x
5. feature_y: transect location y
6. nearest_x: nearest slope location x
7. 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:
