– 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.
For example:
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
At the moment, a minimal subset of the specification is supported, consisting of
the OC
, BP
, LS
and SS
record types.
Carlson Record Information¶
The format is a comma separated ASCII file containing record types, headers, recorded data and comments. The format is based on the Tripod Data System 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 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 Tripod Data System specification is modified to provide enhanced functionality, the added or modified data will reside in comment records to avoid incompatibility with existing software.
Each record is made of one line of text, with comma-separated fields of ASCII text format:
AH,DC%s,MA%s,ME%s,RA%s
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 called an (ENUM). The “Notes” field is introduced by
the --
code and contains a description of the record.
In practice, each point has a unique number and can be referenced for various purposes from other records.
Sideshot records (SS
) reference the Occupy point record in the``OP``
field.

TOPS is capable of converting raw measurement data into local coordinates, by performing a sequential processing of all records in their order.
Known limitations¶
- Support for measurements is still incomplete, here is a list of TODO:
- add all missing code
- get comments
- add the possibility to customize code
