What's in a name?

The dioptra is the original survey instrument developed by Greek Astronomers for use in measuring angles. This tool was used extensively to assist in the growth of the Greek Empire.


What Our Clients Are Saying

I have worked with Dioptra on simple survey work and very complex survey work. Whether the project required a simple survey for purchase due diligence, or a complex topographic survey with dozens of obstacles, Dioptra has the skills and technology to provide what we need. It’s a pleasure working with Dioptra. I will use them again and would recommend them to a friend or peer.

Dioptra consistently displays leadership and innovation in assisting the City of Chubbuck with GIS asset management and LIDAR data collection/mapping. The products they deliver increase our operational efficiencies and reduce potential construction conflicts.

Rodney Burch PLS, City of Chubbuck Public Works Director

The staff at Dioptra are always very responsive and professional. Dioptra continually meets or finishes below the anticipated project budget while delivering quality work. I would not hesitate to continue to work with Dioptra on future projects.
