## Convert Images

Raw images from Basler cameras are automatically decoded. SpatialExplorer has a built-in image converter located in the Tools menu bar, Tools → Convert Images to convert raw images only from Basler cameras for your own use (e.g. loading them into Pix4D or PhotoScan).

It is very important that you do not omit or add even a single image, as the association between exposures captured by the navigation system and image files would break, causing mis-projections in the point cloud.

## Edit Camera Events

The Edit Camera Events option in SpatialExplorer provides a detailed list view of the position and time metadata of all the images associated with the .plp.

SpatialExplorer allows you to import an image list into Agisoft PhotoScan. You will need to export the data as a .csv for use in Agisoft Photoscan. This is done by clicking on the “Export” option and selecting “Export current receptor to CSV file.”

Additionally, you can export the camera data for use in Pix4D by clicking on the “Export” option and selecting “Export current receptor to Pix4D.”

You can also remove camera events with the “Remove Single Event” button. Removing camera events destroys the association between images and events. photos and events.&#x20;

### Write Georeference data into EXIF headers <a href="#write-georeference-data-into-exif-headers" id="write-georeference-data-into-exif-headers"></a>

This option will allow you to write the georeference data from your trajectory (preferably a post-processed trajectory) into the images. If using a post-processed trajectory, make sure it is selected from the drop-down Trajectory menu.

![Selecting post-processed trajectory to georeference image data](/files/-LpV9opodZV9DLJ_TbiS)

When ready, select the 'Write georeference data into EXIF headers...' to include the georeference data into the images.

A dialog window will prompt you for overwrite confirmation to overwrite the image metadata. Make sure you have a backup of all the photos.

## Convert Ladybug Frame Information File to TerraPhoto Timing List

This utility will convert the Ladybug timestamps generated in LadybugCapPro into a timing list in order to use the captured images in Terraphoto.

![How to Access Convert Ladybug Frame Info to TerraPhoto Timing List in SpatialExplorer 5.X](/files/-LtBUCrlcsEdvkVL1koS)

Select the corresponding .txt file containing the Ladybug camera frame information.

![Open text file with Ladybug Frame Info](/files/-LtCGIq_gjODRzxHAtcY)

Confirm the date (Month and day) in UTC time that corresponds to the mission acquisition.

![Confirm the UTC Mission Date of the text file](/files/-LtCH5Mc3kBV4DmfmoVn)

Next select the amount of image files to associate with the events in the Ladybug frame information file. Once the image files are associated with the text file, it will create a TerraPhoto timing list.

## Overwrite EXIF Orientation

The EXIF specification defines an Orientation Tag to indicate the orientation of the camera relative to the captured scene. This can be used by the camera to indicate the orientation automatically with an orientation sensor. SpatialExplorer allows the user to indicate the orientation manually without actually transforming the image data itself via the “Overwrite EXIF Orientation” option.

![How to access Overwrite EXIF Orientation in SpatialExplorer](/files/-LVo4bl8iO765xi2ZdET)

Select the images that you wish to overwrite the EXIF orientation. This can be a single image or multiple images.

![Select images which require EXIF orientation overwrite](/files/-LVo7oNHJByXlNyPU3FM)

Before proceeding you must backup the images. Any changes to the EXIF orientations will be permanent. We highly recommend making a copy of the camX folder before proceeding. Once you’ve created a backup of the images, select the header angle and direction by which the images will be rotated. Click the “OK” button to overwrite the EXIF orientation metadata.

## Create Camera Sessions From Data

This utility allows for the re-creation of a camera session from multiple sources.
