Who builds PLN System?
Jonas Liubinas, a professional land surveyor working in Lithuania. The product is built by someone who did the field work first, not by a software team that researched the industry afterwards.
Why build survey software instead of using an existing tool?
Survey work carries location, instruments, vehicles, calibration dates, and crew availability. Generic project software models none of them, so companies bridge the gap with spreadsheets and messaging apps.
Where is PLN developed and hosted?
In the European Union, by a Lithuanian company, billed in euro. It is priced for small and medium survey firms rather than per seat.
