Visualize, Analyze Landsat, Sentinel and Planet Imagery

GeoPard Satellite Imagery & Vegetation analysis Raw satellite image vs Upsampled vs Contrast Stretching. Field and Regional level.

Earth Observation starts with solid data preparation, including obstacle detection (clouds, shadows) and advanced imagery processing.

GeoPard provides access to a 30+ years archive of processed, calibrated and cleaned satellite image data with comprehensive views calculated against every satellite image.

This allows you to monitor crop development including retrospective analysis and condition assessment, scout for areas with different levels of growth, detect anomalies, and compare your farm with neighboring fields and areas.

We compared and implemented raw Sentinel-2 imagery with an upsampled version (<1m resolution) enhanced through contrast stretching across 20 satellite imagery indices.

All are available in the GeoPard basic monitoring package.

Satellite imagery Provided by GeoPard

Provider	Satellites	Coverage	Global	Frequency	Raw pixel	GeoPard pixel
USGS/NASA	Landsat 5-9	Since 1988	Yes	Every 8 days (2 satellites)	30m	1m
ESA	Sentinel-2	Since 2015	Yes	Every 5 days	10m	1m
Planet Labs	PlanetScope	Every day, since 2020	Yes	±Every day	3.7m	1m

• Real-Time Indices: GeoPard calculates indices in real-time for both full scenes (Sentinel-2 and Landsat) and at the sub-field level.

• Contrast Stretching: Available for each provider, with recalculated indices based on the Area of Interest (AOI) statistics.

• Zoning and Analytics: Imagery supports advanced multi-layer zoning and equation-based analytics, enhancing precision in agronomic decision-making.

It could be utilized for:

• Accurate change detection and anomalies early detection

• Crop monitoring

• Damage assessment (flood, hail, lodging)

• Yield prediction

• Variable rate application maps based on multi-layer zoning or agronomic Equations/Formulas

• Deforestation detection

Controls and Filters

GeoPard solution has the following controls and filters to manage satellite data:

1. Compare layers – allows comparing criteria analytics side by side in a split view

2. Cloud drop-down list with the following values:

• Cloud-free – shows only cloudless images

• Partially cloud – adds partially cloud images

• All images (default) – shows all available satellite image

3. Provider filter – allows filtering images by a provider (Sentinel, Planet, or Landsat)

4. Month and Year filters – allow filtering satellite images by month or year

5. Satellite monitoring section – shows satellite images, which can have the following values:

• Date

• Cloud indicator (partially cloud or cloudy, if you selected this option)

• For cloud-free images, it displays the NDVI index calculated from the image

• Provider name (Sentinel, Planet, or Landsat)

On the field map, you have the following controls:

1. Set of indices

2. Crop by boundary

3. Hide/Show layer

4. Zoom to field

5. Zoom to my location

6. 3D/2D view

7. Zoom in

8. Zoom out

9. Map source (Bing or Mapbox maps)

10. New - Contrast Image - colors based on the statistics for a chosen index within the field boundary
