Makhana Pond Water Spread Monitoring
Pond area, algae bloom Makhana
Mission briefing
Makhana Pond Water Spread Monitoring sits in the special bihar mithila stage of the crop cycle. It runs on a mavic 3m + rgb carrying rgb + ms, and in Bihar the window is kharif at a frequency of monthly. Expect roughly 200ha/hr per sortie, and stand the drone down outside the wind <8m/s envelope — flying past it wastes chemical and risks drift onto neighbouring plots. Readings are interpreted through NDWI water index, so the payload has to output those bands rather than plain RGB. Pond area, algae bloom Makhana On a easy-difficulty mission like this, the cost driver is not the drone — it is the number of return trips and the pilot hours around them, which is what the payback maths on the economics page turns on.
