1.1.2 ECDA-related data elements to cover a wide variety of data capture needs are presented. Not all fields need to be used in all applications. The purpose of this standard is to provide a standard field naming and unit format convention (i.e., data dictionary) for using the various ECDA indirect inspection data elements.
1.1.3 This standard presents an open format that is intended to accommodate the widest probable range of variables that might be required to document an ECDA survey and subsequent investigation. It is not necessary to enter data or comments in all of the data fields–only those applicable to the current study or those necessary to meet operator requirements. This format also acts as a checklist to remind the surveyor(s) of necessary information to be gathered.
