How satellite advice works in Karnataka
Watch is free for any field in Karnataka. You need WhatsApp and your field's location; nothing is installed in the field.
1.2 km × 0.9 km · each square 10 m
A real Sentinel-2 view of farmland near Katol, Maharashtra. The same 10 m view is available for any field in Karnataka.
Your own field
We read the Sentinel-2 pixels inside your field boundary and compare them with your field's own history, so the message is about your field, not your district.
Through the monsoon
When cloud hides the field for weeks, Sentinel-1 radar still shows standing water and the growth trend, and the message says what it could not see.
Water and weather timing
The village forecast and FAO-56 crop-water methods help time irrigation and field checks, week by week.
How each message is computed, and what the satellite cannot see: methods and evidence.
