128 Trimble M3 Total Station User Guide
The Trimble M3 total station supports two data formats for downloaded recorded
internal memory data: M5 format and Nikon raw format.
There is also a simple text file format for point number/name list and point code list.
The data output from the Trimble M3 total station can be used with the Trimble Total
Control
™
software (TTC), Trimble Geomatics Office
™
software (TGO), the
TerraMod el
®
(TM) software, and the Trimble Data Transfer utility.
Trimble surveying instruments are used for measurement functions with different data
processing requirements.
The Trimble M3 total station allows densely packed internal measurement and result
data lines to be output in various formats.
This chapter describes the structure of data format and the type identifier of measured
and calculated values.
B
Tip – All instruments have a serial interface which ensures the data exchange.
B.8 M5 data format
The point identification in the M5 data format is 27-digit, of which 12 digits are used as
point numbers and 5 digits are used as the point code in the Trimble M3 total station.
The original Zeiss M5 data format is the common standard for the current TTrimble
M3 total stations, the Trimble 3300, and all former Elta
®
surveying systems.
All five data blocks are preceded by a type identifier. The three numerical data blocks
have a standard layout comprising 14 digits. In addition to the decimal point and sign,
they accept numeric values with the specified number of decimal places.
The information block is defined by 27 characters. It is used for point identification (PI)
and text information ( for example TI).
The address block is comprised of five digits ( from address 1 to 99999).
B8.1 The M5 data line
The data line of the M5 format consists of 121 characters (bytes). The multiplication of
this figure by the number of addresses (lines) stored shows the size of the project file in
bytes.
Blanks are significant characters in the M5 file and must not be deleted.
The example describes an M5 data line at address 176 with coordinates (YXZ)
recorded in unit m. The point identification of marking 1 is DDKS S402 4201. Column
119 includes a blank (no error code).
