Hardcopy (USA) and field coordinate data (GSA1 and GSA2) were developed in an electronic tabular format. A shapefile was created from this event theme.
To develop locations for transects to measure beach processes
2006-05-01T00:00:00
GSA added nine new profiles to large gap areas
To better understand beach processes and quantify beach erosion and accretion
2014-03-05T00:00:00
GSA added three new profile locations to large gap areas
To better understand beach processes and quantify beach erosion and accretion
2017-04-12T00:00:00
The GSA staff added a new transect on July 27, 2023 labeled DI28.
This transect is to replace DI29 transect due to erosion on Dauphin Island has eroded DI29 to the road and there is no more beach to measure on DI29 transect.

Accuracy of these data is based upon accuracy of the Alabama Department of Transportation (ALDOT) Continuously Operating Reference Stations (CORS). Accuracy is also based on distance from CORS towers and internect connect to the CORS ip address along with the number and configuration of GLONASS and GPS satellites used on the day of surveying each transect.
Satellites are checked periodically during the day of surveying the transects along with connection to CORS ip address.
