Are drawings or photographs uploaded to a server?
No. Image sources are processed locally in your browser while you work and are not uploaded to the JustMeasure server.
Is JustMeasure CAD software?
No. JustMeasure does not replace CAD. It focuses on preparing, calibrating and measuring image-based sources.
Do I need to install anything?
No. JustMeasure runs in a web browser.
Do I have to pay a subscription?
No. JustMeasure uses perpetual licenses, not monthly or annual subscriptions.
How many devices can I use the license on?
One license can be used on up to three devices.
Can I open a project from the PRO version in Basic?
Yes, if the project does not use any feature available only in PRO. If it contains a PRO-only feature, Basic will refuse to open the project.
How accurate are the measurements?
There is no single universal accuracy percentage. The result depends on the quality of the source, the corrections applied, calibration and the precision with which measurement points are placed.
Does a cadastral tab need calibration?
No. Cadastral geometry is georeferenced in S-JTSK / EPSG:5514 and uses metres directly as coordinate units.
Is measurement from the cadastral map as accurate as a land survey?
No. JustMeasure measures directly on the supplied cadastral geometry, but the result is limited by the accuracy of the source ČÚZK data. A cadastral map is not a substitute for a land survey and should not be used as the sole basis for legally determining a property boundary.
