2.6. Recorded Data
The ADV data acquisition software records data in an efficient binary file format. Note
: A differ-
ent file format is used for autonomous data collection with the ADVField internal recorder. See
the ADVField Operation Manual for a description of all data file formats.
At the start of data acquisition, the data acquisition software records several internal configura-
tion settings, as well as the user-specified data collection parameters. In the boundary adjustment
mode, the software records the last measured distance to the boundary. With each sample, the
program records a binary record containing velocity data (three components), SNR data (three
values, one for each receiver), correlation data (three values, one for each receiver), and the cur-
rent value of the event counter. If the ADV has the optional compass/tilt, temperature, or pres-
sure sensors installed, data from any of these installed sensors will also be recorded with each
sample. All the information contained in these data files can be accessed by the data conversion
programs discussed in Section 3.
