# Recorded Datasets

Recorded datasets capture everything collected during a scan, from images and sensor data to control points and quality maps into a single, time-stamped folder. This page explains the structure and contents of that `datasets_rec/<date-time>` folder, so you know exactly where to find anchors, images, sensor data, calibration files, and other key information needed for processing and use in NavVis IVION.

While scanning, images and sensor data are recorded. From the moment you start scanning until you press **Finish**, everything is written to one Dataset, which is a folder containing a number of individual files.

- For each Recorded dataset, a corresponding folder is created named `datasets_rec/<date-time>`.
- A Recorded dataset contains the following folders and files:

| **Folder/File** | **Description** |
| --- | --- |
| `anchors/` | Contains text files with control point information. |
| `anchors/anchors.txt` | Contains the timestamps and names of [Control Points](/v1/docs/control-points-3) entered during the scan. See also [Dataset Control Point Info File](/v1/docs/control-points-reqs). |
| `anchors/anchor_poses.txt `or `anchor_poses.csv` | Contains the measured poses of control points. See also [Control Point Poses File](/v1/docs/control-points-reqs#creating-a-control-point-coordinates-file-poses). |
| `anchors/anchor_poses_recorded/txt` | Contains the poses for [Control Points](/v1/docs/control-points-reqs) as recorded during the scan. |
| `cam/` | Contains captured images. |
| `cam/info.list` | Lists the `*info.json` files created inthe `info/` folder. |
| `info/*.json` | An `*info.json` file (see [Capture Location Info Files](/v1/docs/capture-location-info-files)) is created for each successful capture event (all six cameras have captured an image). |
| `internal/` | Contains internal system information such as calibration data, offsets, and trajectories. |
| `internal/bags/` | Contains bag files with recorded sensor data. |
| `logs/` | See [Logs](/v1/docs/logs). |
| `maps/` | Contains quality map images for the recorded data in different resolutions (see [Quality Map](/v1/docs/quality-map)). |
| `dataset.json` | Contains the dataset name entered by the operator, the version layout (dataset identifier), and statistics such as the mapped area and mapping duration. |
| `sensor_frame.xml` | See [Calibration file](/v1/docs/dataset-artifacts-1#calibration-parameters). |
| `sensor_frame.xml.sig` | Digital signature of the calibration file |
| `qualitymap_rec.png` | Quality map for the Recorded dataset |
| `trolley.cer` | Security certificate for your device. |

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.

Aggregate of data recorded during mapping with a NavVis mapping device. The data needs to be processed to be consumable by applications like NavVis IVION.
