# Mapping Settings for LR1

## Mapping Settings for LR1:

You must update the LR1’s sensor and lens specifications as detailed below when conducting a mapping mission in IGC. This is to ensure proper overlap of images. 

1. In the IGC app on the ground control station, open the Survey / Mapping mission interface by tapping the 'Plan' icon in the menu on the left side of the screen.

| Sensor       | 35.70 mm | 23.80 mm |
| Image        | 9504 px  | 6336 px  |
| Focal Length |          | 35 mm    |

{% hint style="info" %}
Note: The focal length settings correspond to the provided lens.&#x20;
{% endhint %}

5. You may now proceed to plan and run mission as normal.&#x20;

{% hint style="info" %}
The LR1 will not automatically center on NADIR. You may need to manually set the camera to NADIR prior to running your mission.
{% endhint %}
