Carlson SurvCE RW5 Format

This document outlines the Carlson SurvCE RW5 format in detail. The format is a comma separated 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 Carlson SurvCE 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.
