So I bought a Drone Nerds phantom 4 with camera modified for NDVI . According to their documentation, it only records light in the Red (660 nm and NIR bands. They tell me to capture images in RAW so that they can be processed properly using QGIS before using an image stitching software. However, pix4d capture will only shoot in jpg, same for DroneDeploy app. DJI ground station might work.
Am I correct that I need to shoot in RAW?
Am I correct that the image will only have two bands?
Am I correct that pix4d and drone deploy apps are insufficient?
