Raw Data Files
A raw data file is an ASCII text file that is automatically generated
whenever a new job is created on Survey Pro and cannot be created
using any other method. It has the same file name as the current job
file (the job name), followed by the *.RAW extension.
A raw data file is essentially a log of everything that occurred in the
field. All activity that can create or modify a point is written to a raw
data file. Survey Pro never "reads" from the raw data file – it only
writes to the file. Since a raw data file stores all of the activity that
takes place in the field, it can be used to regenerate the original job
file if the job file was somehow lost. This process requires the TDS
Survey Link software.
Since a raw data file is considered a legal document, it cannot be
edited using any TDS software other than appending a note to it
using the View Raw Data screen. Editing a raw data file would
invalidate all of its contents and is not supported in any way by TDS.
When viewing a raw data file on a PC using a simple text editor or on
Survey Pro using the View Raw Data screen, the file is shown
unaltered, which can appear somewhat cryptic. When viewing the file
from within Survey Link, the codes are automatically translated on
the screen to a format that is easier to understand.
