This section outlines the FAST Survey RW5 format.
File Format
FAST Survey RW5 Format
This document outlines the FAST Survey RW5 format in detail. The format is a comma delimited ASCII file containing
record types, headers, recorded data and comments.
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 FAST Survey using the Set
Collection
routine. Essentially, these records are identical to a sideshot record.
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.
