# BLK ARC: Invalid Global Coordinates Upon Import

## Summary

When importing BLK ARC scans, containing georeferenced data, the global coordinates may not be read upon the first import of the raw datainto Cyclone REGISTER 360 PLUS.

## Workaround

The recommended workaround is to import scans twice using specific import settings mentioned in the workflow below:

1. Download the job from BLK ARC using Data Manager.
2. Navigate to **Settings | General** and define Import settings in Cyclone REGISTER 360 PLUS. Ensure SLAM recalculation upon 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 visualise the scans on a satellite map:
  1. Click **Show Geo Image Bar** to visualise 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.
  1. Select **Auto Cloud** in Import settings to automatically align multiple scans.

> [!NOTE]
> **Note**: SLAM recalculation is not mandatory this time to retrieve the GNSS data.
8. Import the data.
