This polyline shapefile provides the boat's XY position, water depth, and water temperature during the collection of continuous resistivity profile data in Greenwich Bay, Rhode Island in May 2009. This shapefile also acts as an archive of this dataset.

The batch processing script was called dohold.
dohold:
files=`ls *.gps | cut -d. -f1` for file in $files do awk -f awkhold $file.gps $file >> may14_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.
This processing step and all subsequent processing steps were performed by the same person - VeeAnn A. Cross. Person who carried out this activity:
gpstime, longitude, latitude, depth_m, temp_c, lineThis text file was then imported to ArcMap 9.2 using Tools -AddXY Data. The X field is longitude, Y field is latitude, and the coordinate system as defined as WGS84. This "Event Theme" was converted to a shapefile by right-mouse clicking on the layer - Data - Export Data. Data sources used in this process:
