Catastrophe Response & Large-Loss Mapping

Insurance | Catastrophe Response & Large-Loss Mapping

When disaster affects an entire area, every decision needs the bigger picture.

Major fires, floods and severe storms can affect multiple properties, essential infrastructure and entire communities.

When damage is widespread, insurers, loss adjusters, engineers and recovery teams need to understand its scale, location and impact across the wider site.

Iprosurv combines aerial imagery, photogrammetry and three-dimensional mapping to create coordinated digital records that support major-loss assessments and recovery planning.

Wennington village fire: aerial documentation supporting an understanding of damage across multiple properties and the surrounding area.

The Challenge

When the damage is widespread, isolated photographs cannot tell the whole story.

A major-loss event may affect numerous properties, roads, services and other assets across an extensive area.

Emergency activity, debris, damaged structures, floodwater and restricted access can make early inspections difficult.

Different insurers, loss adjusters, engineers, contractors and property owners may need information about the same location for different reasons.

Drone mapping can create a consistent visual and spatial record, helping those involved understand the extent of visible damage and coordinate the next stages of assessment and recovery.

Questions That Matter

How extensive is the damage?

Understand the distribution of visible damage across the affected site.

Which properties and assets are affected?

Use mapped imagery to identify buildings, land and relevant infrastructure.

Can everyone work from the same evidence?

Provide a consistent visual reference for authorised stakeholders.

Can the scene be recorded before clearance?

Document accessible conditions before demolition and recovery works change the site.

Catastrophe Mapping Applications

From widespread storm damage to complex multi-property losses.

Professional aerial surveys can help document the extent of an incident and provide useful information for organisations responsible for loss assessment and recovery.

01 / Major Fire

Large Fire & Multi-Property Damage

Map affected buildings, adjoining structures and surrounding areas once the location is safe and authorised for survey activity.

02 / Severe Weather

Storm & Wind Damage Mapping

Document damaged roofs, buildings, fallen trees, access routes and other visible impacts over suitable areas.

03 / Flood Events

Flood Extent & Property Impact

Capture visible flood boundaries, affected properties, infrastructure and surrounding terrain at the time of survey.

04 / Commercial Loss

Industrial & Commercial Incidents

Produce coordinated imagery of warehouses, factories, commercial premises and surrounding operational areas.

05 / 3D Evidence

Digital Reconstruction & Modelling

Create suitable orthomosaics and textured 3D models that support examination of complex sites and spatial relationships.

06 / Infrastructure

Roads, Utilities & Surrounding Assets

Document accessible visible damage to roads, infrastructure and nearby assets for review by responsible specialists.

07 / Shared Evidence

Multi-Stakeholder Information

Organise data so insurers, loss adjusters, engineers and authorised recovery teams can review consistent site records.

08 / Recovery Monitoring

Clearance & Reinstatement Mapping

Conduct planned repeat surveys to document visible changes during debris clearance, demolition and reconstruction.

From Response to Recovery

Mobilise. Map. Share. Support recovery.

Major-loss mapping requires careful coordination, safe operating arrangements and data that is organised around the needs of the people making decisions.

01. Coordinate

Establish site authority, survey scope, operational restrictions and the information required.

02. Capture

Collect appropriate aerial photographs and mapping imagery for subsequent processing.

03. Deliver

Provide organised evidence and further mapping where ongoing recovery monitoring is required.

Technology in Action

One incident. Multiple perspectives. A clearer digital record.

High-resolution imagery: Captures site-wide context and visible damage details.

Orthomosaic mapping: Produces a georeferenced overhead record from suitably overlapping photographs.

Photogrammetry: Creates textured three-dimensional representations of accessible captured surfaces.

LiDAR: Supports suitable spatial surveys using laser-generated point-cloud data.

Optical zoom: Allows targeted visual examination from appropriate stand-off positions.

Repeat surveys: Help document visible changes during clearance and recovery.

The combination of technologies depends on the site, the required level of detail and whether validated spatial measurements are needed.

Digital Evidence Explained

RGB Imaging

Detailed aerial photographs for visual documentation.

Orthomosaic Mapping

A georeferenced overhead record of the surveyed area.

3D Photogrammetry

Textured models allowing users to explore the recorded scene.

LiDAR Point Clouds

Three-dimensional spatial data for suitable technical workflows.

Shared Digital Records

Structured information for controlled multi-stakeholder review.

Understanding Catastrophe Mapping

Can a 3D model help insurers understand a major-loss site?

Yes. A properly produced digital model can provide a consistent visual representation of captured areas, making complex damage easier to examine and discuss.

What the Model Can Support

Review of site layout, visible property damage, relationships between structures and changes during recovery.

What Requires Professional Assessment

The cause of loss, structural stability, hidden damage, liability, policy coverage and repair costs.

Important:
A detailed 3D model is not automatically survey-grade. Measurements require suitable control, accuracy checks and validation.

Iprosurv in Action

A devastated village. One shared digital picture.

Our Wennington village-fire project shows how aerial mapping and 3D reconstruction can help numerous stakeholders understand the same major-loss site.

Real Project | Wennington Village Fire

Mapping damage across multiple properties

Following a devastating fire that destroyed multiple village properties, Iprosurv deployed a DJI Mavic 3E to capture the affected area.

Using DJI Pilot 2, the team planned the aerial mapping mission and processed the resulting imagery into a textured 3D model using gNext Labs software.

The model provided a common visual reference for more than 20 interested parties, including insurers, loss adjusters, engineers and demolition specialists.

What the Data Supported

Rapid documentation

Recording visible site conditions while recovery decisions remained important.

Large-area coverage

Capturing the affected properties within a wider geographic context.

3D reconstruction

Creating an accessible visual representation of the damaged area.

Shared evidence

Providing one consistent reference for multiple interested parties.

Recovery coordination

Supporting discussions about loss assessment, demolition and subsequent work.

Why it matters:
Major-loss events often involve numerous organisations. A shared digital record helps those parties discuss the same location using consistent visual information.

Why It Matters

A clearer overview when many decisions depend on the same evidence.

Drone mapping can complement traditional loss assessment by improving site visibility, reducing some access requirements and supporting more coordinated information sharing.

Understand the Full Extent

Site-wide imagery shows how visible damage is distributed across multiple properties and surrounding areas.

Reduce Unnecessary Exposure

Remote surveys may reduce the need for some personnel to approach damaged or difficult-to-access structures.

Coordinate Stakeholders

Shared records support communication between insurers, adjusters, engineers and recovery organisations.

Planning a Major-Loss Survey

Safe mobilisation and a clear evidence plan come first.

Catastrophe sites can be dynamic, hazardous and subject to emergency restrictions. Inspection objectives and safe operating arrangements should be confirmed before deployment.

Incident coordination:
Confirm site control, permissions and any emergency-service restrictions.

Airspace:
Check for flight restrictions, emergency aircraft and other aviation requirements.

Safety:
Assess unstable structures, debris, hazardous materials and other site hazards.

Coverage:
Establish the properties, land and infrastructure to be documented.

Accuracy:
Define survey control and validation where measurements are required.

Data security:
Agree access rights, confidentiality and retention requirements.

Recovery:
Consider whether repeat surveys will be needed during clearance and reinstatement.

Planning Considerations

What should insurers and loss adjusters consider?

How large is the loss area?

A single commercial facility, several properties or a wider community.

Who controls access?

Establish authority from the relevant site controller.

What evidence is required?

Overview imagery, detailed inspections, mapped data or 3D models.

Who needs the results?

Identify recipients and secure methods of delivery.

When will the site change?

Consider emergency repairs, demolition and debris clearance.
