# Generated Artifacts for each Dataset

The subsequent artifacts are generated by the NavVis software for each separate Dataset.

### 2D Geo-Registration Maps

2D geo-registration maps are generated during post-processing for every Dataset and are output in 10 cm and 2 cm resolutions. These maps provide outlines of the mapped site and serve as basis for refinement in drawing programs. A pixel represents a square of the specified resolution.

### 2D X-Ray Maps

2D x-ray maps are generated during post-processing for every Dataset. These images are rendered from different viewpoints (top-down and side views) with a resolution of 5 cm / pixel. As a result, they provide useful information about mapped buildings and interior structures.

### Beacons

During mapping, the mobile mapping system captures signals from Bluetooth beacons. During post-processing, this information is written to `bluetooth_beacon.csv` in the form of tupels containing the following information:

- The timestamp (in seconds) when the signal was received
- The position of the mobile mapping system x, y, z (in meters) relative to the Dataset's origin
- The orientation of the mobile mapping system relative to the dataset's origin (as a quaternion w, x, y, z)
- The intensity of the signal received in decibel milliwatts
- Data sent by the beacon, starting from the last four bytes of the iBeacon prefix.

### Calibration Parameters

The file `sensor_frame.xml` stores the calibration parameters of the mobile mapping system including cameras, laser scanners, and electrical devices.

> [!CAUTION]
> **Warning:** This is a critical file. Do not modify, rename, or move it to a different location.

### Logs

The `logs` directory contains log files recorded during mapping (in the `datasets_rec` folder) and during data processing (`datasets_proc` and `datasets_web`). The information in these files is important for [Troubleshooting](/v1/docs/technical-support).

A dataset is a piece of a site, the result of a continuous recording with a NavVis mapping device or the result of an imported point cloud. Datasets can contain panoramic images and point clouds.
