– Sokkia SDR 33¶
New in version 0.4.
Sokkia SDR33 is a format used by older models such as Sokkia SET 5F.
The format supports is based on fixed-position fields, with one record per line. SDR33 supports both polar (“raw”) measurements and cartesian coordinates (Northing, Easting, Elevation).
The first four characters of a line are useful to separate the various type of measurements:
prism height is marked by code
03NM
polar measurements are marked by the
09F1
codecartesian measurements are marked by
08TP
base stations are marked by
02TP
, because their coordinates are entered by hand as cartesian coordinates
It is uncommon for polar and cartesian measurements to be found in the same dataset.
