Satellite Imagery
agronome.ai provides satellite imagery for every field with a defined boundary. View vegetation health indices, track changes over time, and compare aerial and satellite perspectives.Data sources

Available layers
| Layer | Bands | What it shows |
|---|---|---|
| Natural Color | RGB | True-color aerial view |
| NDVI | (NIR - Red) / (NIR + Red) | Vegetation health and density |
| EVI | Enhanced vegetation index | Vegetation health in dense canopy |
| CIR | NIR, Red, Green | Color infrared — healthy vegetation appears bright red |
Viewing imagery
- Navigate to a field’s Analyze tab
- Select a date from the timeline
- Choose a layer type (Natural Color, NDVI, EVI, CIR)
- Use the opacity slider to compare with the base map
Tile caching
Satellite tiles are cached in two layers for performance:- Redis — hot cache for recently viewed tiles (TTL-based)
- Google Cloud Storage — persistent cache for all requested tiles
