This is a repository of GNSS data files for stations of interest to the NASA Langley GIS Team.

Currently this consists of the NASA Langley base stations, the NASA Langley subsidence stations and several NOAA stations(sewells pt, yorktown, and kiptopeke)

Archived log files are available in a directory structure similar to that used by NOAA/NGS for CORS.

YYYY/DDD/<stationname>/<datafiles>

Where YYYY is the 4 digit year(eg 2015) and DDD is the day of the year(eg 001-366).
