  • You will receive an email and notification in the Agremo app when the satellite images are ready
  • Maps with cloud coverage over 30% of the field will not be generated
  • Satellite images are 10×10

  • Maps with cloud coverage over 30% of the field will not be generated.
  • Satellite images are 10×10.

How to Access Satellite Maps?

  1. Open field list
  2. Click on the field where satellite maps are generated
  3. Click on the map with the satellite icon in the thumbnail view
  4. Select Stats -> Show analysis results

The analysis number in the field list represents the number of generated satellite maps.

Utilize Satellite Maps

  1. Go to the MAP VIEW tab
  2. The Stats panel consists of general map information, VI histogram, list of VI, and a table with VI values.
  3. Choose a season to filter maps.
  4. Click on the map (box) in the chart with the exact dates of the generated map and NDVI values.
  5. Download the result using the “get result” button.
  6. Download a report to generate a CSV file and PDF report with a comparison of current and previous map VI values.
  7. Click on “share reports” to share data.
  8. Squares in the “Generation date” chart represent a single satellite map, with average NDVI values shown.

Alert System 

  1. Go to the ALERT SYSTEM tab.
  2. Maps with alerts are highlighted in red in the chart.
  3. Click on the map with the alert to access the map with VI values.
  4. Download the report using the “get alert report” button for a comparison of two maps and differences in NDVI values.
  5. Agremo provides two different alerts: Vegetation Emergence Alert and Vegetation Index Drop Alert

 

  • Vegetation Emergence Alert (example)

Understanding Vegetation Indices

Vegetation indices are crucial tools in precision agriculture, providing insights into plant health, growth stages, and environmental conditions.

Here’s a guide to some commonly used indices which you will have with  Agremo:

1. MSAVI (Modified Soil-Adjusted Vegetation Index)

  • Purpose: Assess plant development and uneven growth.
  • Accuracy: Provides accurate data even in low vegetation or plants lacking chlorophyll.
  • Values:
    • 0.2 to 0.4: Seed germination stage.
    • 0.4 to 0.6: Leaf development stage.
    • 0.6: Apply NDVI instead.
  • Usage: Ideal for the early season

2. NDVI (Normalized Difference Vegetation Index)

  • Purpose: Measure vegetation density or biomass
  • Values:
    • Negative: Clouds, water, rocks, bare soil
    • 0.10: Sparse vegetation
    • 0.10: Dense vegetation
  • Usage: Suitable for the growing stage

3. RECI (Red Edge Chlorophyll Index)

  • Purpose: Estimate chlorophyll content in leaves
  • Values: Responsive to chlorophyll content and nitrogen nourishment
  • Usage: Most useful during active vegetation development but not suitable for harvesting season

4. EVI (Enhanced Vegetation Index)

  • Purpose: Evaluate plant health, vegetation density, and biomass
  • Benefits: Enhances sensitivity to high biomass areas and minimizes atmospheric interference
  • Values: 0.20 to 0.80 indicate healthy vegetation
  • Usage: Growing stage

5. NDRE (Normalized Difference Red Edge Index)

  • Purpose: Assess plant health, particularly in permanent or later-stage crops
  • Values:
    • 0.2 to 0.6: Unhealthy or immature crops
    • 0.6 to 1: Healthy, mature, ripening crops
  • Usage: Maturity and pre-harvest stages

6. NDMI (Normalized Difference Moisture Index)

  • Purpose: Detect moisture levels in vegetation
  • Values: Range from -0.2 to 1, indicating varying levels of canopy cover and water stress
  • Usage: Throughout the growing season

7. NDWI (Normalized Difference Water Index)

  • Purpose: Measure surface water presence
  • Values:
    • 0.2 to 1: Water surface
    • 0.0 to 0.2: Flooding, humidity
    • -0.3 to 0.0: Moderate drought, non-aqueous surfaces
    • -1 to -0.3: Drought, non-aqueous surfaces
  • Usage: Throughout the growing season

Each index offers unique insights into different aspects of vegetation health and growth, empowering farmers to make informed decisions for optimal crop management.
