Survey3 is available in both a wide angle lens version (Survey3W) and narrow angle lens version (Survey3N). Both lenses are non-fisheye and extremely low distortion, which provide great results when aerial surveying or in other applications. The Survey3W is similar in field of view to most DJI cameras (Mavic, Phantom, Inspire X3) and the medium FOV on a GoPro Hero. The Survey3N provides a 2X optical fixed zoom over the Survey3W, providing 2X higher ground sample resolution (GSD).


Survey3 cameras each come with an external GPS receiver to provide instant geo-tagging with every captured image. By upgrading to our Advanced V2 GPS option (+$40USD) you will gain better positional accuracy, especially in your altitude measurements. Once the camera has GPS lock you will hear 6 beeps. Locating the GPS receiver with a clear view of the sky and not obstructed (such as underneath a drone) provides better location accuracy.


Survey3 supports the ability to receive a PWM signal to not only trigger the cameras to capture a photo, but also to have the camera go into USB Media Transfer mode. This allows you to have the camera always connected to a computer (such as a drone companion computer) and mount/unmount the camera's SD card. Once mounted you can extract the images, process them and save them to a more easily accessible storage device.


With Survey3 we also introduced our new triple-band multispectral filters:


Orange+Cyan+NIR (OCN)

Red+Green+NIR (RGN)

NIR+Green+Blue (NGB)



Spectrum Peak Spectrum Width Filter Model Image Channel
475nm 15nm NGB 3
490nm 36nm OCN 2
550nm 15nm NGB, RGN 2
615nm 42nm OCN 1
660nm 15nm RGN 1
725nm 23nm RE 1
808nm 50mm OCN 3
850nm 30mm NGB, RGN, NIR 1,3,1


The OCN & RGN filters are often used for indices such as NDVI, GNDVI, OSAVI, TVI, CVI, etc. The NGB filter is often used for the ENDVI index. We also provide a visible light color (RGB), rededge (RE) and near infrared (NIR) filter option.
