Do the programs and gadget that transfer GPS-info to, e.g., cameras,
also transfer information of the geodetic datum used when recording this
particular set of coordinates? If not, the accuracy is less than 2 km.
Many field collectors seem to be unaware of the importance of the
geodetic datum. When reviewing taxonomy papers that include geographic
coordinates with great details I always demand the datum [e.g. EUR50,
WGS84 or RT (if in Sweden)] mentioned, or fewer digits included. It
often turns out that authors don't know what I am talking about!
