   This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.

3. Free stationing - Wikipedia

   en.wikipedia.org/wiki/Free_stationing

   The pole of this local polar coordinate system is the vertical axis (pole O) of the total stations. The polar coordinates (r,f) with the pole are transformed using surveying software on a data collector to the Cartesian coordinates (x,y) of the known points. The coordinates for the position of the total station are then calculated. [5]

4. Total station - Wikipedia

   en.wikipedia.org/wiki/Total_station

   A total station or total station theodolite is an electronic/optical instrument used for surveying and building construction. It is an electronic transit theodolite integrated with electronic distance measurement (EDM) to measure both vertical and horizontal angles and the slope distance from the instrument to a particular point, and an on ...

7. Theodolite - Wikipedia

   en.wikipedia.org/wiki/Theodolite

   The modern theodolite has evolved into what is known as a total station where angles and distances are measured electronically, and are read directly to computer memory. In a transit theodolite , the telescope is short enough to rotate about the trunnion axis , turning the telescope through the vertical plane through the zenith ; for non ...

8. Grading (earthworks) - Wikipedia

   en.wikipedia.org/wiki/Grading_(earthworks)

   Section through railway track and foundation showing the sub-grade. Grading in civil engineering and landscape architectural construction is the work of ensuring a level base, or one with a specified slope, [1] for a construction work such as a foundation, the base course for a road or a railway, or landscape and garden improvements, or surface drainage.

9. Level (optical instrument) - Wikipedia

   en.wikipedia.org/wiki/Level_(optical_instrument)

   The complete unit is normally mounted on a tripod, and the telescope can freely rotate 360° in a horizontal plane.The surveyor adjusts the instrument's level by coarse adjustment of the tripod legs and fine adjustment using three precision levelling screws on the instrument to make the rotational plane horizontal.
