The purpose of this dataset is to provide the raw continuous resistivity profile data collected by the USGS on May 15, 2009 in Greenwich Bay, Rhode Island using the AGI SuperSting system.

The batch processor was dohold.

files=`ls *.gps | cut -d. -f1` for file in $files do awk -f awkhold $file.gps $file >> may15_09_gps.txt doneUnder Cygwin, all of the hold files were concatenated into a single comma-delimited text file and a header line added to the file. The header line added to the text file was: gpstime, longitude, latitude, depth_m, temp_c, line. Using ArcMap 9.2 - Tools - Add XY Data, the comma-delimited text file was added as an event theme to ArcMap. No erroneous points were detected. Person who carried out this activity:
