Survey2 Cameras
We offer 6 different filter options for the Survey2 cameras.
Choose one of the filters below for more information.
Visible RGB
This camera captures Visible Light RGB color similar to our eyes. Most of the time this camera is used as a reference image to compare with the results from the other cameras, but it can also be used for many other uses such as 3D photogrammetry. The images from this camera can be processed in any ortho-mosaic generating program.

NDVI Red + NIR
This camera has a dual-band filter that captured reflected Red light in the RGB sensor's red channel and reflected Near Infrared light in the RGB sensor's blue channel. You can thus use this single camera to compute the NDVI indice, though the contrast in the resulting index image will not be as "accurate" as using the separate Red and NIR camera models. The images from this camera can be processed in any ortho-mosaic generating program.

Near Infrared (NIR)
This camera captures the reflected NIR light in the RGB sensor's red channel. This camera is used in many different indices such as NDVI, ENDVI, SAVI, etc. The images from this camera can only be processed in any ortho-mosaic generating program that uses a shared DSM between image sets (such as Pix4D).

Red
This camera captures the reflected Red light in the RGB sensor's red channel. This camera is used in many different indices (such as NDVI, EVI, SAVI, etc) and to combine with the Green and Blue cameras to make a RGB Visible Light color reference image. The images from this camera can only be processed in any ortho-mosaic generating program that uses a shared DSM between image sets (such as Pix4D).

Green
This camera captures the reflected Green light in the RGB sensor's red channel. This camera is used in many different indices (such as GNDVI, GVI, etc) and to combine with the Red and Blue cameras to make a RGB Visible Light color reference image. The images from this camera can only be processed in any ortho-mosaic generating program that uses a shared DSM between image sets (such as Pix4D).

Blue
This camera captures the reflected Blue light in the RGB sensor's blue channel. This camera is typically used to compute indices such as EVI and to combine with the Red and Green cameras to make a RGB Visible Light color reference image. The images from this camera can only be processed in any ortho-mosaic generating program that uses a shared DSM between image sets (such as Pix4D).
