Agricultural Land Monitoring application
Rural Support Service (RSS) of the Republic of Latvia employs satellite data in daily
practice not only for classification of agricultural crops and monitoring purposes,
including identifying areas where a pond or building has been excavated to exclude
the possibility of receiving area-based payments for such fields, but also for mapping
flood-affected and burnt areas in grassland fires. Image below represents the detected
area of grassland fire.
RSS already has the following functionality implemented:
• Convenient access to the latest Sentinel-2 cloud-free composite image
mosaics and Sentinel-1 data, ensuring up-to-date and readily available satellite
imagery.
• Normalized Burn Ratio (NBR) calculations using Sentinel-2 images taken
before and after a grass fire, enabling change detection and generating burned
area masks for specific regions as needed. These masks are then converted
into vector format. Currently, the masks undergo manual analysis and manual
adjustments to eliminate false positive responses caused by cloud shadows,
melting snow moisture, and soil erosion.
• Delineation workflow for flooded agricultural lands (after heavy rains, melting
snow) using both Sentinel-2 and Sentinel-1 data. The processing workflow
includes calculation of water index using multispectral values, radar
backscatter values and thresholding to create a water area mask. Water masks
are generated at the start and end of specific time periods of interest and are
compared to extract the flooded areas by identifying the changes between the
two time points. Currently, the process is not tailored to effectively handle the
processing of large-scale areas.
• Test workflows in Google Earth Engine (GEE) for faster acquisition of the
results.
Improvements: During the course of the project RSS is planning to make the following
improvements to the service:
• Implement automation in the production of burned area masks across
extensive areas, incorporating enhanced functionality to minimise false
positives.
• Usage of the combined advantages of Sentinel-2 and Sentinel-1 data for
accurate delineation of flooded areas.
• Implement automation in the production of flooded area masks.
• To provide a service to any end user with the flexibility to define the specific
conditions for processing Sentinel-1 and Sentinel-2 data algorithms according
to their requirements.
Benefits of the achieved results
Both burnt and flooded agricultural land maps ensure objective and consistent
assessments of agricultural lands affected by those risk factors. By employing
standardised image processing techniques and analysis, the maps generated provide
reliable and comparable information across different locations and time periods. The
satellite or aerial imagery captures the actual conditions on the ground, providing a
reliable record of the affected areas. This objectivity can help mitigate disputes and
provide a basis for objective analysis and decision-making. As new satellite images
become available over time, it becomes possible to track changes in the extent and
severity of flooding, monitor water recession, and assess the recovery progress of
affected agricultural lands. These timely updates support ongoing monitoring efforts
and adaptive management strategies. This complies with CAP recognizing need
for risk management through insurance or support for the farmers through
different development and financial assistance programmes.
Information content:
1) burnt area map delineating agricultural lands affected by grassland fires,
2) flooded agricultural land map.
Both maps will be prepared in raster and vector format.
