Water is one of the most important variables in viticulture. Too little water can reduce berry size, accelerate canopy stress, and suppress yield. Too much irrigation can dilute fruit quality, increase disease pressure, and waste increasingly expensive water resources. Yet despite its importance, vineyard water dynamics are still often monitored using sparse measurements and manual field observations.

TerraView™ ET Intelligence was built to change that.

Transforming Earth Observation into Vineyard Intelligence

Using freely available Sentinel-2 satellite imagery, SWEEP cloud workflows, and machine learning models, TerraView™ transforms Earth observation data into operational vineyard water intelligence.

The goal is simple: Help growers better understand vineyard water dynamics across entire blocks — from space.

What Is ET?

Evapotranspiration (ET) represents the combined movement of water through:

• Evaporation from soil and surfaces
• Transpiration through plant canopies

ET is closely linked to:

• Plant water use
• Canopy activity
• Vine stress
• Irrigation demand

ET Indicators and What They Tell Us

High ET often corresponds to:

• Active transpiration
• Healthy canopies
• Strong physiological activity

Low ET may indicate:

• Water limitation
• Drought stress
• Canopy decline
• Heat-related stomatal closure

For vineyards, ET patterns can reveal:

• Irrigation variability
• Moisture stress hotspots
• Changing canopy water demand through the growing season

Why Sentinel-2?

One of the most exciting aspects of TerraView™ ET Intelligence is that it uses freely available Sentinel-2 imagery.

Sentinel-2 provides:

• 10–20 m multispectral imagery
• Global coverage
• ~5 day revisit frequency
• Calibrated surface reflectance products

This makes Sentinel-2 extremely powerful for operational vineyard monitoring. For many vineyards, Sentinel-2 provides enough spatial detail to:

• Monitor vineyard blocks
• Quantify canopy vigor
• Estimate moisture dynamics
• Identify spatial stress patterns

Most importantly: Because the imagery is free, TerraView™ can scale operational intelligence workflows without relying entirely on expensive commercial imagery subscriptions.

How TerraView™ ET Intelligence Works

TerraView™ uses SWEEP cloud workflows to automate vineyard ET intelligence generation. The workflow includes:

1. Vineyard Geometry Input

Users upload:

• Vineyard block polygons
• GeoJSON files
• Shapefiles
• Or draw vineyard boundaries directly

2. Sentinel-2 Scene Retrieval

SWEEP automatically:

• Searches Sentinel-2 archives
• Filters cloudy scenes
• Selects high-quality imagery
• Retrieves data for the reporting period

3. Spectral Analysis

TerraView™ computes:

• NDVI (Normalized Difference Vegetation Index)
• NDMI (Normalized Difference Moisture Index)
• NDWI (Normalized Difference Water Index)
• SAVI (Soil-Adjusted Vegetation Index)
• Moisture-related predictors

These layers capture important vegetation and water dynamics.

4. ET Model Inference

Machine learning models estimate relative ET patterns using:

• Multispectral Sentinel bands
• Vegetation indices
• Temporal dynamics
• Canopy moisture indicators

5. Operational Intelligence

The workflow generates:

• ET maps
• Vineyard stress zones
• Block summaries
• Temporal trends
• Management insights

ET Intelligence Is About Patterns

Absolute ET estimation is difficult and often requires:

• Weather stations
• Thermal imagery
• Energy balance models
• Extensive calibration

TerraView™ instead focuses on operational relative ET intelligence.

In practice, growers often care most about:

• Where anomalies exist
• Which blocks differ from the vineyard norm
• How conditions are changing through time

Relative ET intelligence is often far more operationally useful than uncertain absolute estimates.

Heat Waves, Water Stress, and Climate Change

As heat waves become more frequent, vineyard water monitoring is becoming increasingly important. Extreme heat can rapidly alter:

• Transpiration
• Canopy water demand
• Vine physiology
• Moisture stress dynamics

Satellite-derived ET intelligence provides a scalable way to monitor these changes across entire vineyards. TerraView™ can help identify:

• Moisture stress hotspots
• Declining canopy vigor
• Irrigation response variability
• Persistent stress zones during extreme conditions

What Growers Receive

TerraView™ ET deliverables may include:

• ET intelligence maps
• NDVI and moisture summaries
• Vineyard stress indicators
• Temporal ET trends
• Block-level analytics
• Monthly vineyard intelligence reports

Reports are automatically:

• Processed in the cloud
• Rendered into operational dashboards
• Uploaded to S3
• Distributed through automated workflows

Built on SWEEP Cloud Workflows

TerraView™ ET Intelligence is powered by SWEEP.

SWEEP orchestrates:

• Satellite processing
• Raster analytics
• Cloud-native workflows
• Automated report generation

This architecture allows TerraView™ to:

• Scale operational vineyard monitoring
• Automate monthly intelligence products
• Deliver consistent analytics across many vineyards simultaneously

Open Models and Reproducible AI

The TerraView™ ET model is available on Hugging Face.

This includes:

• Model checkpoints
• Inference workflows
• Example notebooks
• Documentation

The Future of Vineyard Intelligence

TerraView™ ET Intelligence is only the beginning.

Future workflows may integrate:

• Sap flow sensing
• Distributed microclimate monitoring
• Berry counting
• Irrigation optimization
• ET forecasting
• AI-assisted vineyard recommendations

The long-term vision is a vineyard intelligence platform that combines:

• Earth observation
• Field sensing
• AI
• Cloud workflows

into a unified operational decision-support system.
