After a long day of topographical surveying, the surveyor connects the Sokkia SET 530 to the office laptop via a 7-pin to 9-pin serial cable. ProLink 1.15 is launched, and the data is downloaded at 9600 baud to a .GSI file, ready for plotting in AutoCAD Civil 3D.

Following the merger of Topcon and Sokkia, software development transitioned to the MAGNET suite. MAGNET Office provides native, cutting-edge support for all legacy SDR formats alongside modern GNSS and robotic total station data processing. It handles CAD drafting, surface modeling, and corridor design natively. 2. Sokkia Link

It supports a wide range of Sokkia instruments, including SDR series, Total Stations (SET), and GPS/GNSS receivers.

: Version 1.15 was released on February 18, 2008 , and remains the most prevalent version in use for legacy Sokkia equipment support.

The "story" of is a trip down memory lane for the surveying industry, representing a pivotal era when field data first began to transition smoothly into the digital office environment.

Running the .exe in Windows XP (Service Pack 3) compatibility mode often resolves "Run-time error" issues common with older 16-bit or 32-bit applications.

Here is a typical daily workflow using Sokkia ProLink Version 1.15.

ProLink processes raw field observations—such as horizontal angles, vertical angles, and slope distances—and reduces them into definitive 3D coordinates (X, Y, Z or Northing, Easting, Elevation). Additionally, if surveyors use descriptive feature codes in the field (e.g., "EP" for Edge of Pavement, "TRE" for Tree), ProLink can interpret these codes to automate layer management during the CAD export process.
