Survey3 Cameras

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 the Survey2, 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 GPS option (+$30USD) 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.

New to Survey3 is the ability to send 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). 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 indice. We also provide a visible light color (RGB), rededge (RE) and near infrared (NIR) filter option.

Our most popular Survey3 model for assessing plant health is the Survey3W Orange+Cyan+NIR (OCN, NDVI).
