autoanton

Irrigation water balance calculator for wheat fields. Uses WAPOR-3 satellite data (AETI, rainfall, reference ET), Supabase irrigation records, and crop coefficients to compute daily water deltas per field.

Setup

1. Clone the repo

git clone https://github.com/shorbaji/autoanton.git
cd autoanton

2. Install dependencies

uv sync

3. Authenticate with Google Cloud

WAPOR-3 raster data is fetched from Google Cloud Storage. Authenticate with:

gcloud auth application-default login

4. Configure Supabase

Create a .env file in the project root:

SUPABASE_URL=https://your-project.supabase.co
SUPABASE_PUBLISHABLE_KEY=your_publishable_key

5. Required data files

• fields.geojson — field boundaries (16 fields, A-1 through D-4)
• kc.csv — crop coefficient (Kc) values by date and field

Both are included in the repo.

Usage

Open ai.ipynb and run the cells. The notebook fetches data, caches it locally under data/, and calculates the water balance:

from utils import fetch_aeti, fetch_ret, fetch_rainfall, fetch_irrigations, fetch_kc, calculate_water_delta

planting_date = datetime.date(2025, 12, 10)

aeti = fetch_aeti(planting_date)
rainfall = fetch_rainfall(planting_date)
ret = fetch_ret(planting_date)
kc = fetch_kc()
irrigations = fetch_irrigations(field_ids=list(range(37, 53)), field_names=field_names)

water_delta = calculate_water_delta(irrigations, kc, rainfall, ret)

Satellite rasters are cached in data/aeti/, data/rainfall_pcp/, and data/ret/ so subsequent runs skip the download.
