Method

From orbit to field decision

We combine Sentinel-2 satellite imagery with agronomic threshold calibration to identify precisely where and when your vineyard needs attention.

ESA Sentinel-2 Acquisition

European Space Agency Copernicus imagery at 10 m resolution — openly licensed, globally available, every 5 days. Cloud-filtered and atmospherically corrected via Google Earth Engine. Covers every vineyard region on earth: Austria, Italy, France, Moldova, but equally New Zealand, Australia, South Africa, Chile, and Argentina. Season timing adapts automatically to hemisphere — Northern or Southern.

ESA COPERNICUS · GOOGLE EARTH ENGINE · GLOBAL

Multi-Index Computation

Six spectral indices computed per block: NDVI (canopy density), NDRE (chlorophyll/nitrogen proxy), NDMI (leaf moisture), EVI (soil-corrected biomass), BSI (bare soil exposure), NDWI (water content verification).

QGIS + PYTHON PROCESSING

Percentile Calibration — No Customer Data Required

We calibrate against your estate's own Sentinel-2 history — up to 8 years of archive data, publicly available at no cost. Each block is evaluated relative to itself, not against global averages. A Sangiovese block at altitude has structurally different NDVI values than one in the valley — percentile calibration accounts for this automatically. Known stress years (2003 heat, 2017 frost, 2022 drought) are identifiable directly in the archive — no yield records needed. All we need from you is your vineyard boundary polygon.

Actionable Field Report

A prioritised report with spatial maps, trend analysis, disease risk assessment, irrigation decision support, and drone waypoints for targeted scouting. Delivered as PDF within 48 hours.

DECISION SUPPORT DOCUMENT

NDVI

Vegetation Index

Primary canopy density and biomass indicator. Reliable from budburst through flowering.

PRIMARY: April – June

NDRE

Red-Edge / Chlorophyll

Detects nitrogen deficiency and physiological stress 1–2 weeks before NDVI shows decline.

PRIMARY: July – harvest

NDMI

Moisture Index

Leaf water content via SWIR bands. Most reliable irrigation trigger at Sentinel-2 resolution.

CRITICAL: flowering, véraison

EVI

Enhanced Vegetation

Corrects for soil background. Stable in April when canopy cover is below 50%.

VALIDATION: all season

BSI

Bare Soil Index

Rising BSI + falling NDVI signals canopy loss — defoliation, hail, or disease damage.

ALERT: if rising after June

OSAVI

Soil-Adjusted Index

Corrects for mixed-pixel conditions in 10 m imagery. R² 0.84–0.87 vs. UAV multispectral.

PREFERRED for block means

Field Validation

Estate A, Central Europe — flowering alert detected 10 days early

Spring 2026. Sentinel-2 multi-temporal analysis across a 39 ha estate. Varieties: Fetească Neagră, Rară Neagră, Cabernet Sauvignon.

Between May 16 and May 26, the satellite detected a simultaneous decline across four indices — NDVI (−0.056), EVI (−0.050), NDMI (−0.049), NDRE (−0.031) — coinciding precisely with the onset of flowering. A single-index decline could indicate normal anthesis effects. A four-index simultaneous decline during the highest-risk disease window of the season is an actionable stress signal.

The report identified 29 priority drone waypoints, quantified a 4× performance ratio between best and worst blocks (NDVI 0.181–0.716), and triggered an immediate irrigation decision assessment based on NDMI trending toward the coulure risk threshold.

"The report provided a level of spatial detail and index interpretation we had not seen from satellite analysis before. The multi-index approach caught patterns we would have only discovered during field scouting." — Director of R&D, undisclosed estate · 2026

UAV PROGRAMME · WORLDWIDE

The satellite tells you where to fly.
We give you everything to fly it right.

Sentinel-2 identifies stress zones at 10 m resolution. A multispectral drone at 3–10 cm GSD resolves individual vine rows. Maply bridges both worlds — from training your team to delivering flight-ready data and hardware solutions, anywhere in the world.

01

Training

Three-level programme from UAV basics to full satellite-to-drone workflow integration. Delivered on-site anywhere in the world or remotely. DJI-compatible. Includes EU and local regulatory frameworks.

Differentiation

Why Maply does this differently

⊕

Multi-index, not just NDVI

Most reports show one index. We compute six simultaneously. A stress event confirmed by NDVI, NDRE, NDMI, and EVI together is not a false alarm — it is a field emergency.

◈

No sensitive data required

We need one thing from you: your vineyard boundary polygon. No yield records, no historical harvest data, no agronomic logs. Calibration runs entirely on the public Sentinel-2 archive — 8 years of your estate's own satellite history, already available.

◻

No agronomic overreach

We are geospatial engineers, not agronomists. We identify where stress exists and how severe it is. Field decisions stay with your team and your crop protection advisor.

◯

Drone-ready output

Every report includes prioritised waypoints for UAV inspection. We tell your drone where to fly — you collect the row-level detail Sentinel-2 cannot resolve.
