Raw Data</p>
<p>12.1	File Format</p>
<p>Carlson SurvPC RW5 Format</p>
<p>This section outlines the Carlson SurvPC RW5 format in detail. The format is a comma delimited ASCII file containing record types, headers, recorded data and comments.</p>
<p>The format is based on the RW5 raw data specification, with the exception of angle sets. Angle sets are recorded as BD, BR, FD and FR records to allow reduction of all possible data that can be recorded by Carlson SurvPC using the Set Collection routine. Essentially, these records are identical to a sideshot record.</p>
<p>With the exception of the aforementioned angle set records, if the RW5 specification is modified to provide enhanced functionality, the added or modified data will reside in comment records to avoid incompatibility with existing software. SurvPC writes latency in the GPS notes record of the RW5 file.</p>
