FlyCRE Wildfire Intelligence
California Wildfire Risk Assessment and Fuel Modification Intelligence
Multispectral, Thermal & Visual Property Assessment
Wildfire risk isn’t always visible.
FlyCRE combines high-resolution aerial mapping, multispectral vegetation analysis, radiometric thermal imaging, and historical change detection to provide a more complete view of fuel-modification conditions across commercial properties and portfolios. FlyCRE serves cities, fire agencies, HOAs, and commercial property teams in wildland urban interface communities across California.
1) High-Resolution Visual Mapping
3) Radiometric Thermal Imaging
2) Multispectral Vegetation Analysis
4) Historical Change Detection
Illustrative analysis.
A Defensible Space Inspection Is Only the First Layer
Fuel-modification conditions do not remain static. Vegetation regrows, dead material accumulates, irrigation performance changes, and maintenance can gradually depart from an approved plan. Large properties, steep slopes, perimeter areas, and difficult terrain can also be challenging to inspect and document consistently from the ground. FlyCRE creates a comprehensive aerial record that helps stakeholders identify visible concerns, investigate vegetation-condition patterns, document completed work, and monitor change over time.
Four Layers. One Complete Property Record.
High-Resolution Visual Mapping
Document visible vegetation density, apparent fuel continuity, defensible-space conditions, emergency access routes, slopes, property perimeters, and maintenance conditions.
See the entire property—not just isolated ground-level viewpoints.
Multispectral Vegetation Analysis
Capture information beyond ordinary visible light to identify relative patterns of vegetation vigor, stress, decline, and inconsistent landscape treatment. Multispectral analysis can highlight areas that warrant closer inspection before changes become readily apparent.
Reveal vegetation-condition patterns beyond standard aerial imagery.
Radiometric Thermal Imaging
Map apparent surface-temperature differences and identify unusual thermal patterns, irrigation inconsistencies, heat-retaining areas, and locations requiring targeted investigation.
Add a surface-temperature layer that helps direct attention to areas requiring further evaluation.
Historical Change Detection
Compare repeat inspections to document vegetation regrowth, completed maintenance, recurring concerns, and seasonal or year-over-year changes.
Move from a one-time snapshot to a repeatable record of changing property conditions.
The advantage is not four separate images. It is four aligned layers connected to the same property locations.
From Aerial Data to Property Intelligence
FlyCRE transforms coordinated sensor data into organized, location-based findings that property teams can review, assign, document, and compare over time.
01
Define the Scope
Identify the property, structures, fuel-modification zones, defensible-space areas, access routes, and inspection objectives.
02
Capture the Property
Collect coordinated visual, multispectral, and thermal datasets using a structured aerial workflow.
03
Align the Layers
Connect the captured datasets to the same property locations.
04
Analyze Conditions
Identify visible concerns, vegetation-condition patterns, thermal anomalies, and areas requiring closer evaluation.
05
Deliver the Record
Organize findings into clear, geolocated, decision-ready documentation.
06
Track Change
Repeat inspections to document maintenance, regrowth, recurring concerns, and changing conditions.
Decision-Ready Fuel Modification Documentation
Depending on the property and defined scope, deliverables may include:
- High-resolution aerial property maps
- Multispectral vegetation-condition maps
- Radiometric thermal imagery
- Geolocated observations
- Fuel-zone and defensible-space documentation
- Annotated areas requiring follow-up
- Before-and-after comparisons
- Prioritized maintenance observations
- Portfolio-level summaries
- Timestamped inspection records

Changes occurring between inspection cycles
Aerial intelligence helps property teams direct ground inspections and maintenance resources to the locations that need attention. It does not eliminate the need for qualified ground verification.
Fuel Modification Is Not a One-Time Project
A one-time inspection captures one moment. FlyCRE establishes a repeatable historical record. Consistent seasonal or annual inspections help property teams verify completed work, identify regrowth, monitor recurring concerns, and maintain visibility across large properties and portfolios. California defensible space requirements under PRC 4291, local fire authority fuel modification plans, and the state's new Zone 0 ember-resistant zone rules all assume conditions are maintained over time, not verified once. Repeat aerial capture gives you a timestamped record of brush clearance, thinning, and irrigation condition across every zone, inspection after inspection.

Document completed work and compare corrected areas with previous observations.
Apply a consistent inspection and reporting process across multiple properties.
Longitudinal Documentation
Create timestamped records that support maintenance planning, vendor oversight, and institutional risk management.
Move Beyond the Checklist
Visible inspection shows what the property looks like. Multispectral analysis adds vegetation-condition patterns. Thermal imaging adds surface-temperature intelligence. Historical monitoring shows how conditions change. One property. Four synchronized layers. One decision-ready record. See the risk before fire season does.
Inspection Scope
FlyCRE assessments document visible, spectral, and thermal conditions present at the time of data collection. Multispectral and thermal observations identify patterns and anomalies for further evaluation; they do not independently determine actual fuel-moisture content, combustibility, wildfire probability, or fire-code compliance unless supported by an appropriately calibrated and validated methodology. FlyCRE assessments do not replace inspections, approvals, certifications, or compliance determinations issued by CAL FIRE, a local fire authority, an authority having jurisdiction, or another appropriately qualified professional. Requirements must be evaluated against the property’s approved fuel-modification plan and applicable local regulations.
California Defensible Space and Fuel Modification FAQs
What are defensible space Zones 0, 1, and 2 in California?
Zone 0 is the ember-resistant zone within 5 feet of a structure. Zone 1 extends from the structure to 30 feet, and Zone 2 extends from 30 to 100 feet or to the property line. Requirements vary by jurisdiction and by local fire authority fuel modification plans. FlyCRE documents conditions across all zones in a single aerial capture.
​
What is a fuel modification zone?
A fuel modification zone is a strip of land, commonly 100 to 170 feet, where vegetation is modified or maintained to slow an approaching fire and give firefighters defensible ground. Many California communities in the wildland urban interface have recorded fuel modification plans that HOAs and property owners are responsible for maintaining.
​
How often should fuel modification zones be inspected?
Local fire authorities commonly inspect annually, and vegetation conditions change season to season. Repeat aerial capture before and after maintenance work, and before peak fire season, creates a documented timeline of conditions rather than a single snapshot.
​
​Does an aerial assessment replace a fire authority inspection?
No. FlyCRE assessments document conditions and support your maintenance and compliance efforts. Compliance determinations are made by your local fire authority. Our deliverables help you prepare, verify completed work, and maintain records.
