The purpose of this point shapefile is to provide the parsed data from the raw HYPACK (VER 9.0.5.17) navigation files. The parsed data will contain latitudes, longitudes, and depth values. The depth values are particularly necessary to fill depth data gaps in the continuous resistivity profile GPS data.
donav: files=`ls *.RAW | cut -d. -f1` for file in $files do awk -f awkit $file.RAW > $file.navdep doneThe AWK script "awkit" simply extracts any line of information in the HYPACK file that contains either the string "GPGGA" or "SDDBT" and writes this information to a new file with the extension navdep.
awkit: { if ($0 ~ /GPGGA|SDDBT/) { print $0 } }This process step and all subsequent process steps were performed by the same person - VeeAnn A. Cross. Person who carried out this activity:
