We need to survey about 23,000+ Hectares of agriculture land and wondering what drone options we got given
(a) We have to survey really large area and small amount of time.
(b) We need to scan whole area say 3-4 times in a 8 months, over the season of crop to record growth.
(c) RGB + NDVI camera is good enough for now.
(d) Drone which is easy to repair, as I am sure there will be many crashes during operations..
Would it make more sense for to assemble it our own given we would need bunch of them, and we would need quick turn around time in case of repair/crash...
