Total Open Station

Total Open Station in action

What it does

Total Open Station (TOPS) downloads survey data from total stations on your computer, from almost any operating system.

Data you download can be archived as is, and exported to exchange formats (CSV, DXF, GeoJSON, ...) for use in CAD or GIS software.

The program is written with simplicity in mind, it is very small and fast.

Total Open Station is a stand-alone Python application. It comes already packaged in Debian, Ubuntu, Linux Mint and OpenSUSE. Others (including Windows users) can get it from the Python package index, or install it directly with:

pip install totalopenstation
More detailed instructions are available in the user documentation (please note we are updating the documentation to the most recent version).

Using it

  1. start the program
  2. connect your total station with a serial or serial-to-USB cable
  3. insert the serial connection parameters like baudrate and bytesize
  4. download your data...

That's it. You can review raw data immediately, save it to an ASCII file for later processing, or export directly to an exchange format.

If you have a lot of data to process, or you're more technically inclined, the same features are available as command-line programs or a programming library (just import totalopenstation in your app).
