Satellite Imagery as a Valuable Tool for the New Common Agricultural Policy 2023–2027 

On 1 January 2023, the new Common Agricultural Policy for years 2023–2027 entered into force. Hand in hand with the provided subsidies goes the necessity for monitoring and controls, which falls to the individual Member States. Therefore, an efficient, reliable, and cost-effective source of data is needed. Such source is Very High Resolution (VHR) satellite imagery. It allows you to conduct in-depth analysis of plant and soil conditions, map land use at wide scales with incredible detail and accuracy, and ensure that agricultural goals are being met. Read more about how exactly VHR satellite imagery can assist you with the New CAP – based on our 20 years’ experience with the programme.

About the new CAP

The new Common Agricultural Policy (CAP) is the EU’s long-standing framework for supporting agriculture and rural development across its member states. The current CAP period, spanning from 2023 to 2027, represents a shift towards a more sustainable and environmentally conscious approach to agricultural practices. It is aiming to support farmers, help tackle climate change, and maintain rural landscapes across the EU. To achieve this, the policy presents 10 key objectives: 


  1. To ensure a fair income for farmers. 
  2. To increase competitiveness. 
  3. To improve the position of farmers in the food chain. 
  4. To take climate change action. 
  5. To promote environmental care. 
  6. To preserve landscapes and biodiversity. 
  7. To support generational renewal. 
  8. To foster vibrant rural areas. 
  9. To protect food and health quality. 
  10. To foster knowledge and innovation. 


One of the defining features of the current CAP is its strong emphasis on sustainability and precision agriculture. By leveraging technology, such as remote sensing, the policy aims to optimise resource utilisation, reduce environmental impact, and increase agricultural productivity. Since EUSI has 20 years of experience in assisting member states and other stakeholders with CAP-related activities, as well as the highest-quality satellite imagery, we have established processes that are highly effective in meeting these goals.

The role of satellite imagery in CAP

Satellite imagery plays a crucial role in monitoring and evaluating agricultural activities, enabling more targeted and data-driven decision-making processes. Very High Resolution (VHR) imagery enables the precise mapping of land parcels, crop types, vegetation health, soil moisture and more, allowing for better management of agricultural resources and targeted interventions where needed.  

“In optical satellite imagery, Very High Resolution refers to sub-meter resolution. For precise mapping and crop identification, you need 30–50 cm resolution.”

Benjamin Schumann, Earth Observation Support Specialist at EUSI

The integration of satellite data into the CAP’s implementation framework is expected to increase transparency, accountability, and the overall effectiveness of the policy’s measures. By providing comprehensive and up-to-date information, VHR satellite imagery empowers stakeholders, from policymakers to farmers, to make informed decisions and adapt their practices accordingly.

Having extensive experience with CAP and related programmes, we have found VHR satellite imagery especially helpful for these applications: 

  • vegetation classification 
  • soil analysis 
  • large-scale collections 
  • landscape features and biodiversity 
  • CwRS (Controls with Remote Sensing) programme 

Vegetation classification: learn the type, health and age of plants from a single image

You can use 8-band satellite imagery to accurately classify crops based on their type, health, and growth stage, and utilise this data for the distribution and control of financial support from the EU. How does it work? 

8-band imagery

Human eye can see the colour bands in the wavelength spectrum of 400–700 nm (nanometres). However, satellite sensors can display more; they show the wavelengths that are invisible to human eyes, such as near-infrared or red edge. While some satellite providers deliver imagery with four bands, EUSI is the only provider in Europe and North Africa who offers eight bands. (Additionally, EUSI delivers bands captured in the short-wave infrared (SWIR) domain, which is valuable for soil analysis – read more about it later in the article.) 

  • Human eye: the visible spectrum – coastal, blue, green, yellow, red  
  • 4-band imagery: blue, green, red, and NIR1 (near-infrared) 
  • 8-band imagery: coastal, blue, green, yellow, red, red-edge, NIR1, NIR2 
  • SWIR: 8 bands in the short-wave infrared spectrum 


In the image below, move the slider to compare a 4-band image (red and NIR1) and an 8-band image (red edge and NIR1):

8-band satellite imagery for vegetation classification

When a plant is illuminated by the sun, part of the energy is absorbed and part is reflected, which we can represent by a curve called a spectral signature. The spectral signature is visible only in multispectral satellite imagery. 

For each plant, the signature is slightly different, depending on chlorophyll activity, plant type, age, and health, allowing you to determine the characteristics of crops important for subsidy controls. However, it is strongly dependent on location – it will differ across terrain types, altitudes, and geographical regions. For example, in one area, bright red might mean strong and healthy plants, whereas in another area, bright red might signify trees attacked by bark beetle. Therefore, in order to conduct vegetation classification, you must be familiar with the specific region and always combine multispectral imagery with a ground sample. 

Thanks to this, you gain objective and accurate information about plant species and field sizes. This data can be used to distribute subsidies and control farmers’ declarations in a precise and discreet way, without the farmer knowing they are being controlled. 

See the image below to compare different resolutions and 4 vs 8 bands: 

To carry out controls, you upload the results of image analysis in a database which already contains information based on what the farmers declared. The database will crosscheck the data and notify you if there is a discrepancy – in which case you perform further checks like field visits. This method is more accurate, objective, and discreet than relying on the manual control of farmers’ declarations. 

Analysing soil with SWIR imagery: moisture, health, and carbon content

Just like 8-band imagery, SWIR (Short-Wave InfraRed) satellite images reveal wavelengths that are invisible to the human eye. SWIR can be used to monitor soil moisture content, which is crucial for agriculture. Not only because the shortage or overabundance of water may mean the plants will die, but also because knowing the levels of soil moisture can help predict natural disasters, manage irrigation, determine whether a field is prepared for agricultural processing, and further optimise farming activities.1

Why not just use soil moisture sensors? The advantage of satellite imagery is that it can map large areas in a single image, allowing you to replace physical soil analysis with a faster and more economical solution.  

Multispectral imagery shows soil organic carbon levels

Furthermore, multispectral imagery is a valuable tool for topsoil mapping. By analysing multispectral imagery, scientists can map soil organic carbon levels, nutrient concentrations, and other vital soil traits with incredible accuracy and detail.  

Soil organic carbon (SOC) is a key indicator of soil health and fertility. Higher SOC levels are associated with better soil structure, water retention, nutrient cycling, and productivity for crops. Thanks to SOC mapping, farmers can identify areas prone to degradation or in need of carbon sequestration efforts, optimise fertiliser inputs, and comply with regulations. That leads to reducing not only costs but also agricultural impacts.2  

Satellites are especially valuable for this application thanks to two factors: 

  • high revisit rate (the newly launched Maxar WorldView Legion satellites significantly increase the revisit rate, making it possible to collect the area even multiple times a day) 
  • unprecedented spatial resolution (3.7 metres SWIR with the Maxar constellation, or pan-sharpened multispectral up to 30 cm). 

Large-scale collections with near real-time delivery

For region- or even country-wide collections, remote sensing is a cost-effective method that can cover a large area, including a large number of small zones, in a matter of minutes. For example, the Maxar WorldView-3 satellite can collect over 7,000 km2 in a single pass. That’s an image 66 km wide, stretching all the way from the Italian cities of Milan to Genoa, from Salzburg to Linz in Austria, or from Oxford to Cambridge in the UK.  

The large image strips and quick delivery times mean that you can receive all your data within important growth cycles. Whereas with aerial or drone imagery you have to stitch together images collected at different times and during different weather conditions, satellites bring a homogenous overview.  

The imagery is directly downlinked in near real-time and available within hours through our recently upgraded ground station in Munich, Germany. Flexible planning can be adjusted up to 15 minutes before each collection including change of AOI and sensor, and priority tasking can be activated for rapid collection. We guarantee a 15% or lower cloud cover. 

Using Maxar’s top-of-the-class satellites, we offer resolutions up to native 30 cm. In these VHR images, you can see details such as individual plants, hedges, cattle, and field boundaries. With access to a proprietary HD technology, imagery can be additionally processed to provide 15 cm resolution over entire strips.

Our VHR satellite imagery can support you in accurately identifying Good Agricultural and Environmental Conditions (GAECs), crop type, land cover type, land maintenance, landscape elements and landscape feature quantification. In addition, our data can be used for the independent control of your LPIS reference system.  

Monitoring landscape features and biodiversity

One of the key objectives of CAP is to contribute to reversing biodiversity loss. For that, collaboration with farmers is needed. “Farmers play a vital role in preserving biodiversity. They are among the first to feel the consequences when biodiversity is lost but also among the first to reap the benefits when it is restored,” says the EU Biodiversity Strategy for 2023. “At the same time, certain agricultural practices are a key driver of biodiversity decline. This is why it is important to work with farmers to support and incentivise the transition to fully sustainable practices.” 

The target is to bring back at least 10% of agricultural area under high-diversity landscape features. Farmers can achieve that by (re)introducing riparian vegetation, hedges, buffer strips, terrace walls, or non-productive trees, or ponds. Numbers speak clearly: 

  • Restoring only 15% of ecosystemsin priority areas cancut extinctions by 60%.3 
  • Forest restoration and better farm practices could curb the pollution of water supplies for 81% of cities globally.4
  • Approximately 12 million hectares of severely eroded croplands in the EU contribute to an annual loss in agricultural productivity of 1.25 billion Euros.5 


VHR (Very High Resolution) satellite imagery can significantly help with monitoring the implementation of sustainable practices and evaluating their impact. In images with 30 cm resolution, you can see individual trees, vegetation patches, small water bodies, or migration corridors for wildlife species.

“At least 25% of the EU’s agricultural land must be organically farmed by 2030.”

Example from Romania

To protect the sensitive habitat of Romania’s Hartibaciu region, Muncons SRL deployed WorldView-2 high-resolution satellite imagery with an integrated GIS solution and web portal to develop a land management plan. 8-band images were used for automatic and semi-automatic habitat classification, including land, water courses, infrastructure, and developed areas such as buildings, roads and industrial zones, and the supplemental web portal included interactive maps of endangered species distribution, areas of vegetation, agriculture, preservation lands and environmental hazards. Thanks to this solution, the World Wildlife Fund was able to save a significant amount of money because fewer field specialists were required to complete the project. Read the case study. 

CwRS Programme: Controlling agricultural subsidies

The European Commission has encouraged using Controls with Remote Sensing (CwRS) to control agricultural subsidies granted under the EC’s Common Agricultural Policy. After the real-life evaluation in 2003 and the successful operation in 2004, the EC’s Joint Research Centre now provides VHR satellite data to EU Member States for their CwRS-based subsidies. 

EUSI helped initiate the programme in 2004 and has been a reliable contributor since, with success rates close or equal to 100% every year. We have the benefit of operating our own ground station in Munich, Germany, which, in combination with manual satellite tasking based on real-time weather conditions, leads to the speedy delivery of data for distribution to the EU Member State administrations. We are able to deliver the imagery in near-real time, thereby assisting and enabling the administrations to manage their own deadlines. 

  • In 2013, we had 100% success over a total of 213 control sites. About half the sites were collected within 7 days of the collection window start time, and the rest within 15 days of the window opening. 
  • In 2015, the demand for imagery for the CwRS programme increased by more than 40% reaching 497,000 km² across 950 control sites. We collected more than half of the sites within 14 days of the window opening and about one third within 7 days – with a 100% success rate. 
  • In 2017, cloudy weather over Latvia, the UK, and Ireland made the operation particularly challenging. But once again, EUSI finalised the collection of nearly half a million square kilometres of satellite imagery for the CwRS programme with a 100% success rate. 
  • In 2019, EUSI had 714 acquisition windows for each of the 628 agricultural zones spread all over Europe using Maxar‘s WorldView-2, WorldView-3 and GeoEye-1 sensors. Despite weather challenges, we managed to collect images for approximately 63% of the zones completely cloud-free. 
  • Acquiring a total of 361,991 square kilometres, 2020 was the fourth year in a row that we proficiently completed the collection with a success rate of 100%. 
  • In 2021, manual weather assessments contributed to the high success rate of the collection over zones with an average cloud cover of 0.6%. 

“Direct tasking allows EUSI to minimise cloud cover, increase collection efficiency, enable customer flexibility and shorten delivery times.”

Nicole Enghuber, Earth Observation Support Specialist at EUSI
