Reading Africa From Orbit: Turn Free Satellite Data Into a Farm-Advisory Service
Turn free satellite data into a paid farm-advisory service — the data and NDVI, the limits, ground-truthing, pixels into advice, the tools and the business. Orientation, not agronomic advice; the data is free, the advice is the business.

What you'll gain
Public satellites give away vast amounts of high-quality imagery of every farm in Africa, every few days, for free — and almost no one pays for the pixels. They pay for timely, interpreted, actionable advice. This course is the honest playbook for building an Earth-observation farm-advisory business, and it is clear from the first line: the data is free, the advice is the business, and this is orientation and capacity-building — not a guarantee of a contract, a customer or accurate predictions, and not agronomic, financial or investment advice. You learn what the free data actually is — the Sentinel satellites and Landsat, and coarse-but-frequent MODIS — and the three properties (spatial, temporal and spectral resolution) that decide what any dataset can and cannot do. You learn to read the pixels: why optical sensors fail under cloud and radar sees through it, and the vegetation indices — above all NDVI — that turn light into a signal of vegetation vigour over time. And you learn the honesty at the core of the field: that satellite data is a proxy, not ground truth; that NDVI is not yield; and that a low patch on a map tells you where and when something changed, never why — only ground-truthing tells you the cause. You learn the use cases an EO advisory actually sells (crop monitoring and anomaly detection, within-field variability, moisture and drought, timing, area estimation, and the objective triggers behind index insurance), that the value is the interpreted, delivered decision rather than the map, and that delivery is half the product. You learn the free and low-cost tools (Google Earth Engine, QGIS, Sentinel Hub, Python or no-code paths), the skills you truly need, and the business — the models, and the honest money reality that the data is free but ground-truth, compute, delivery and customer acquisition cost, and that willingness-to-pay usually sits with aggregators (cooperatives, agribusinesses, insurers, lenders, government), not individual smallholders. It closes with the classic mistakes and the line between honest advisory and a scam — the guaranteed-yield and guaranteed-return schemes that dress themselves in satellite and AI language — with a red-flag grammar and the discipline that defeats them. Two Nigerians travel with you: Ada, who builds the analysis and advisory engine, and Musa, who ground-truths and delivers the advice. Where a price, spec or accuracy could not be fixed, the course tells you to confirm it live and to ground-truth and partner with agronomists rather than inventing it. This is orientation and capacity-building, not a guarantee of a contract and not agronomic, financial or investment advice.
