2.5 Media summaries

Acoustic and image data are all summarized at the organization level in the corresponding Recordings and Camera Deployments tabs. This allows you to navigate through each data type to gain more insight about where / when data were collected and which locations were surveyed across projects and years by comprehensively managing thre media. 

You’ll immediately notice that the summaries for these data are different. Why is this? A few reasons:

  • Data collection
    • Cameras can be set to motion capture and / or time-lapse (take pictures at regularly defined times)
    • ARUs are pre-set to a schedule for when and how long they will record
  • Data volume—the unit of measurement here is a “single” media unit (one image vs one minute of audio)
    • A single image file is usually < 1 MB
    • A single uncompressed audio file (i.e. CD quality) around 10-minute in duration is usually ~100 MB (100x as large)
  • Survey design
    • With cameras, even though a subset of images may be tagged by a user, all images are uploaded to WildTrax from an image set
    • With ARUs, the amount of data collected at a single location outweighs the ability for a human to process all acoustic information. Therefore, a subset of recordings is chosen to be processed

With these considerations in mind, WildTrax groups the information from cameras to indicate the start and end date which is effectively called a camera image set. Since ARU data is typically never fully uploaded or processed in WildTrax, this information is simply presented with the recording date and time at which the recording occurred.

  • You can click on the for any row of data in either the recordings or camera deployments tab to display overview information for each media type.
  • Clicking on the project name will take you directly to the camera or ARU task so you can hear the audio or look at candid critter snapshots.

Within the recordings tab you can find summaries of the following information:

  • Location
  • Recording date
  • Task count (how many times the task was processed)
  • Audio length (seconds)

Clicking on the will show the projects the recording is associated with.

You can delete recordings by clicking on the  and selecting . If the button is greyed out it means there are still tasks and / or tags associated to the recording. You will need to delete these in the project first before removing the media. 


Clicking on the button in the recordings tab will allow you to select one option from the dropdown to . The spreadsheet will provide you some information on the follow in order to create tasks more easily in projects. 

If you have multiple methods or users assigned to the recording, the list will populate with a scroll bar.


Within the camera image sets tab you can find summaries of the following information:

  • Location
  • Start date
  • End date
  • All image count
  • Motion image count
  • Task count

Clicking on the will show the projects the recording is associated with.


Let’s end the chapter with the Map tab and wrap everything up about organizations. We’ll then move on to Projects.
