Site Survey Metadata

2 files exist:
1) gps_site_surveys.csv
2) levels_site_surveys.csv


***********************************
gps_site_surveys.csv reports topographic data that was acquired with a kinematic, survey-grade GPS unit.
Field data was collected in static mode and post-processed to be corrected with base-station data 
collected at benchmark at either Lake Fryxell or Lake Bonney camp.

In gps_site_surves.csv, data is organized in the following columns:
Site - Plot location, noting in general, the waterbody to which the plot is adjacent
Location_ID - within-plot notation (#X) where the # represents which of 4 parallel transects along the wetted zones that were sampled, and X is the letter representing the sampling site along the transect.
northing_(m) - northing in meters, UTM
easting_(m) - easting in meters, UTM
elevation_(m) - elevation in meters, relative to EGM 96 approximates sea level
comments - comments on specific locations within the 4 transects at each plot (site)


***********************************
levels_site_surveys.csv reports local topographic data for plots that were too far away from a base station
to reliably collect data with survey-grade GPS.  Thus, an engineering level and taper were used to acquire
this data.

In the levels_site_surveys.csv, data is organized in the following columns:
Site - Plot location, noting in general, the waterbody to which the plot is adjacent
Location_ID - within-plot notation (#X) where the # represents which of 4 parallel transects along the wetted zones that were sampled, and X is the letter representing the sampling site along the transect.
dist_fr_shore_(m) - lateral distance, from the shoreline along the slope, in meters
transect_distance_(m) - easting in meters, UTM
elevation_(m) - level, relative to elevation of the autolevel, which was not moved during any survey
