"Recommendation A10. Global Positioning System receivers used for
recording the latitude / longitude of recovered debris must all be
calibrated the same way (i.e., using the same reference system), and
the latitude / longitude data should be recorded in a standardized
format."

The solution I've used is to extract data as directly as possible from
the GPS receiver straight into a GIS. Interim format can be GPX files,
for instance. In other words, keep the data native to GPS/GIS. Excel
isn't appropriate to the job in these cases.

This gets around the "calibration" problem. Pencils & spreadsheets
cause similar problems.

Rather than reporting data (haphazardly, apparently), the searchers
should've submitted their devices for data extraction by GIS types.
