NGV/Survey3d is a customizable web application to collect data, in 3D, while offline.

Switch to offline mode, then:
- navigate the scene;
- see all defects, filter them;
- add or edit defects;
- fill in your form;
- load pictures;
- ... and synchronize to your backend when back online.

The application can be fully customized with:
- your collection areas;
- your 3d tilesets;
- your imagery;
- your form properties and its rules;
- your backend APIs;
- your authentication system.

Many tools are available:
- measures;
- coordinates in local projection;
- clipping polygons.

The solution is opensource, based on CesiumJS.
We are actively developing it with the support of our clients.
