safeguarding
since survey can be an expensive process sensible precaution should be taken to ensure that the work is not compromised, safeguarding is concerned with the protection of work . observations which are written down in the field must be in a permanent , legible, unambiguous and easily understood form so that others may good sense of the work .
observations and other data should be duplicated at the earliest possible stage , so that if something happens to the original work the information is not lost .
this may be by photocopying field sheets, or making backup copies of computer files . whenever the data is in a unique from or where all forms of the data are same place, then that data is vulnerable to accidental destruction.
in the case of acontrol survey , the protection of survey moments is most important since the precise coordinates of a point which no longer exists or cannot be found are useless.
