How Scout Map works

Scout Map is a free, interactive map of viticultural potential. It lets you check whether a given location is suitable for a vineyard - without leaving home.

How to use it

1. Open the map - go to map.vineyardelf.com/a/scout
2. Click on the map - pick the location you are interested in
3. Review the results - the app fetches the data and displays a score

What Scout Map analyzes

🏔️ Topography (digital elevation model)

• Elevation above sea level - every 100 m means roughly 0.6°C less
• Slope - 5-15° is optimal (cold air drains away)
• Aspect - S/SW/SE gives the best sun exposure

🌍 Soil (ISRIC SoilGrids)

• Soil type - sandy-loam is best for grapevines
• pH - optimal 6.0-7.5
• Composition - sand-to-clay ratio

🌡️ Climate (Open-Meteo ERA5)

• Growing degree days - at least 1000°C for most varieties
• Frost days - fewer than 3 days/year = low risk
• Rainfall - optimal 500-800 mm per year

🍇 Registered vineyards

• Existing vineyards - see where grapevines are already grown, based on the official vineyard register
• Popular varieties - which varieties grow in the region

Scoring 0-100

The algorithm rates each location on a 0-100 scale:

• 80-100 - excellent potential (green)
• 60-79 - good potential (yellow)
• 40-59 - moderate potential (orange)
• 0-39 - poor potential (red)

Features

📍 Point collection

You can save multiple locations to compare them:

1. Click “Add to collection” on the selected point
2. Repeat for other locations
3. Compare the results in the “Collection” section

🔗 Sharing

• Copy link - copy the URL with the coordinates to your clipboard
• Share - send it via SMS, WhatsApp or other apps
• The link contains all saved points

🖨️ Printing

Print a report with the list of points, coordinates and location descriptions.

Data sources

Limitations

• The data is indicative - before buying a plot we recommend field surveys
• Soil can vary locally - it is worth analyzing a sample
• The microclimate may differ from regional data

Next steps

Once you find a promising location you can:

1. Install a Scout sensor - collect real data across a season
2. Contact us - we will help with the analysis
