 - `/data/raw/raw_lidar`: This is the raw pre/post storm aerial LIDAR which was taken for the June 2016 storm. `.las` files are the raw files which have been processed into `.tiff` files using `PDAL`. Note that these files have not
 been corrected for systematic errors, so actual elevations should be taken from the `processed_shorelines` folder. Obtained November 2018 from Mitch Harley from the black external HDD labeled "UNSW LIDAR".
 - `/data/raw/profile_features`: Dune toe and crest locations based on prestorm LIDAR. Refer to `/notebooks/qgis.qgz` as this shows how they were manually extracted. Note that the shapefiles only show the location (lat/lon) of the dune crest and toe. For actual elevations, these locations need to related to the processed shorelines.
+- `/data/raw/profile_features_tom_beuzen`: This mat file contains dune toes and crests that Tom Beuzen picked out for each profile. This is used as a basis for the toe/crest locations, but is overridden from data contained in `/data/raw/profile_features_chris_leaman`.
+- `/data/raw/profile_features_chris_leaman`: An excel file containing manually selected dune toes, crests, berms and impacts by Chris Leaman. The values in this file should take preceedence over values picked by Tom Beuzen.
