carlson_rw5 – Carlson SurvCE Raw Data File Format (RW5)

New in version 0.4.

Carlson RW5 is an exchange format used by the Carlson SurvCE software.

The official documentation about the format is provided on the Carlson website.

RW5 is a rich format for raw data about the entire field operation of total stations and even GPS. At the moment, a minimal subset of the specification is supported, consisting of the OC, BP, LS and SS record types.

Each record is made of one line of text, with comma-separated fields:

OC,OP111,N 16556174.237,E 942130.662,EL 16.404
BK,OP111,BP108,BS0.00000,BC0.00000
LS,HI5.684,HR5.500
SS,OP111,FP108,AR0.00000,ZE0.00017,SD3.3566,--FENCE1

The first field is a two-letter code of the type of record. All the following fields are composed with 1- or 2- letter field codes (such as OP, N `` or ``FP) and numeric values. The “Notes” field is introduced by the -- code and contains a description of the record.

Sideshot records (SS) reference the Occupy point record in the OP field. In practice, each point has a unique number and can be referenced for various purposes from other records.

TOPS is capable of converting raw measurement data into local coordinates, by performing a sequential processing of all records in their order.
