7.2. Measurement Site Information
Measurement Site Information, commonly referred to as “Metadata”, should be
documented before any measurements are performed with the FlowTracker2 instrument.
In most organizations, FlowTracker2 measurements are related to a measurement site
and secondary data sets and it’s essential that the information collected is accurate. The
measurement site information that should be collected during a field measurement
exercise is listed in Table 7:3.
Unique entry fields were developed in the FlowTracker2 software for the measurement
site information defined in this section. The dedicated fields ensure that information is
captured correctly and assigned to respective variables, which promote good data
management practices.

Organizations that make use of hydrological databases, unique monitoring site
identifiers and import routines, would find the Site Number very useful to automatically
link the data to a specific monitoring site during the import process.
