## What is viDoc?

The viApps becomes a real surveying and documentation device in connection with a viDoc Hardware. You can position yourself globally or locally on your construction site for daily documentations and surveying work. The app communicates with its own correction data service (e.g. SAPOS) and allows you to measure with centimeter accuracy. The algorithmic compensation functions must ensure the position accuracy. With the app you confirm a full-fledged GNSS rover with single point measurement function, stake out function, distance and area measurement.
The app allows you to take photos with time data tracking for guided documentation. By exporting this data locally, it is possible to keep construction diaries and guidelines. The Photos can be used for photogrammetric model calculations.

In addition to this, a cloud processing service is offered for 3D point cloud models. Active target tracking is used here. These are the pass points, which are also signaled as black and white target marks, can be safely recognized and seen with the help of AI. Through this you will hear extremely 3D models with absolute coordinates. Please be sure that the used service provider is able to work with this generated informations.

Use the data manager to import and export data. The Layerstructure gives you the chance to handle you measured data.
