Hazards | Use cases

Climate hazards

Monitor floods, droughts, and wildfires to minimize damage and enhance resilience. Identify the extent and impact of flooding, track landscape susceptibility to drought, and plan mitigation measures. After wildfires, determine burned areas, assess vegetation loss, and monitor regeneration. Optimize protection and recovery efforts based on data-driven insights.

Floods

Mitigate the effects of floods, predict their course, and design and monitor protective measures

Create or update flood maps for your area and identify impacts on flooded land
Accurately predict the dynamics, frequency, and intensity of flood peaks based on flood risk data models
Assess the effectiveness of flood control measures

Our clients receive actionable insights into:

Extent of flooding – based on data from optical and SAR images taken during the flood
Development, dynamics, frequency, and intervals of flood peaks – based on analysis of historical satellite images
Flood depth – derived from digital terrain models or hydraulic modeling
Susceptibility – modeling results serve as the basis for multi-factor risk assessments including vulnerability factors and populations and infrastructure exposure to floods

Drought monitoring

Measure rainfall, optimize drought remedial interventions, and track their effectiveness

Monitor and evaluate rainfall regularly and adapt to trends in agricultural or forested land use
Observe the impact of drought on vegetation or economic production
Identify drought-prone areas and optimize remedial actions for resulting damage
Select the most suitable locations for interventions, determine priorities, and monitor the effectiveness of measures taken

We use EO-based vegetation cover indicators that enable regular monitoring of drought risk and assessment of its spatiotemporal distribution and severity.

Our clients receive tailored services for monitoring crop production damage caused by drought or other meteorological phenomena.

Burned area detection

Gain insights into wildfire spread and damage, design preventive measures and monitor regeneration

Immediately after a fire, identify the exact extent of the burned area and quantify vegetation loss
Comprehensively assess impacts on soil cover and adapt new planting to changed conditions
Monitor the rate of regeneration in affected areas
Use data to prevent forest fires

We detect and evaluate changes between pre- and post-event satellite images, providing fast and reliable information on the extent of burned areas.

Specialized vegetation indices can help determine the degree of vegetation damage.

Vegetation regeneration processes are evaluated based on time series of satellite data after fire events.

Retrospective inventorization

We use advanced methods like change detection, machine learning, and InSAR to assess the extent, intensity, and progression of disasters or potential hazards. Archival satellite imagery allows for retrospective analysis of past occurrences and their impacts. Our findings are delivered as a product or used to model territorial susceptibility and contribute to multi-factor risk assessments, accounting for vulnerability and exposure to natural hazards.

Proactive monitoring

We monitor optical and radar satellite images to detect precursors to catastrophic events. These detections dynamically recalibrate susceptibility models and parameterize disaster probability scenarios. Monitoring proceeds in phases, with evaluation frequency tailored to client needs.

Choose how to get results

We deliver mapping and measurement results in formats and protocols customized to customer requirements: as spatial data with a time component, through the InSARviz online platform (interactive visualization tool for satellite SAR interferometry), through your API, or as a technical report with maps.

Artificial corner reflectors

We allow you to take or refine InSAR measurements in locations where surface characteristics, vegetation, and other influences would normally hinder standard InSAR deformation mapping.
