# Georeferencing of BLK ARC Scans Collected During the BLK ARC-UI Outdoor Missions

Scans collected with BLK ARC during autonomous outdoor missions with the GA03 GNSS antenna (BLK ARC-UI) can be now georeferenced using the positioning information collected and stored in the B2G file.

With this feature, it is possible to have the global coordinates available for each point of the processed point cloud.

## **Workflow Overview**

To import BLK ARC scans containing georeferenced data into Cyclone REGISTER 360 PLUS, follow the steps below:

1. Download the job from BLK ARC using the Data Manager.
2. Drag and drop the data contained in the job folder into Cyclone REGISTER 360 PLUS.

3. (Optional) Use the map to visualize the scans on a satellite map:
  1. Click **Show Geo Image Bar** to visualize the satellite view.
  2. Locate your site and click **Get Image**.
  3. Click **Place by Geo Coordinates** to automatically place the scan according to the global coordinates.
  4. Double-click the SiteMap to centre the view.
  5. Select the **Coordinate System** in the Import Options and define other Import and Registration settings.
  6. Select **Auto Cloud** in Import settings to automatically align multiple scans.
4. Import the data.

## **Alternative Workflow**

If the global coordinates are **not read upon the first import of the raw data** into Cyclone REGISTER 360 PLUS, it is required to import scans twice using specific import settings mentioned in the workflow below:

1. Download the job from BLK ARC using the Data Manager.
2. Navigate to **Settings | General** and define Import settings in Cyclone REGISTER 360 PLUS. Ensure SLAM recalculation upon the import is enabled by choosing one of the settings below:
  1. **BLK: Re-Run SLAM**
  2. **BLK: Use Re-Observation**

3. Drag and drop the job folder into Cyclone REGISTER 360 PLUS and import the data.
4. Remove the imported scan from the project or delete the project altogether.
5. Import **the same** B2G file again:
  1. Drag and drop the B2G file into Cyclone REGISTER 360 PLUS.
6. (Optional) Use the map to visualize the scans on a satellite map.
  1. Click **Show Geo Image Bar** to visualize the satellite view.
  2. Locate precisely the environment and click **Get Image**.
  3. Click **Place by Geo Coordinates** to automatically place the scan according to the global coordinates.
  4. Double-click the SiteMap to centre the view.
7. Select the **Coordinate System** in the Import options and define other Import and Registration settings.

> [!NOTE]
> **Note**: SLAM recalculation is not mandatory this time to retrieve the GNSS data.
  1. Select **Auto Cloud** in Import settings to automatically align multiple scans.
8. Import the data.
