Automating Catastrophe Exposure Reviews: From Policy Schedules to Geospatial Reports in Minutes - Catastrophe Modeler (Property & Homeowners, Specialty Lines & Marine)

Automating Catastrophe Exposure Reviews: From Policy Schedules to Geospatial Reports in Minutes — Built for the Catastrophe Modeler
Catastrophe modelers live under constant deadline pressure. One week it’s pre-bind due diligence on a coastal Property & Homeowners schedule; the next, it’s a Specialty Lines & Marine accumulation refresh for port terminals ahead of reinsurance placement. The bottleneck is rarely the cat model itself — it’s the messy, inconsistent inputs trapped across property schedules, declarations pages, coverage summaries, and reinsurance submissions. Extracting clean locations, peril terms, deductibles, and limits from these documents and then geocoding them fast enough for a decision window is where time vanishes.
Doc Chat by Nomad Data removes that bottleneck. It reads entire policy schedules and submissions at once, extracts locations from policy schedules with precision, automates geocoding for insurance policies through your preferred geocoding provider, and generates geospatial exposure reports in minutes. Purpose-built for insurance, Doc Chat’s AI-powered agents transform document chaos into standardized, model-ready SOVs and maps you can trust for AI for catastrophe exposure analysis, capacity management, and reinsurance negotiations.

The Catastrophe Modeler’s Reality in Property & Homeowners and Specialty Lines & Marine
In Property & Homeowners, you’re reconciling COPE details and peril sublimits across thousands of addresses that arrive as spreadsheets, PDFs, and scanned attachments. Street names are abbreviated in fifteen different ways, construction details sit in footnotes, and critical modifiers like roof shape or secondary water resistance hide in a coverage summary appendices or endorsement lists. One missing deductible or untagged coastal risk can swing PML and AAL, jeopardize rate deployment, or undercut reinsurance negotiation leverage.
In Specialty Lines & Marine, the problem doubles in complexity. Schedules might list vessels by IMO number, terminals by UN/LOCODE, containers by yard or berth, and cargo by voyage with rolling timestamps. Accumulations must be calculated across ports, terminals, cargo storage yards, and transit corridors. Perils include windstorm, storm surge, earthquake, flood, wildfire, and, for marine, port-specific exposures and stacking constraints that change with tides and operational schedules. Parsing a reinsurance submission to build an exposure bordereau that reflects the real footprint is a race against the clock.
How the Process Is Handled Manually Today
Most catastrophe exposure reviews still lean on manual steps. Teams open PDFs of declarations pages, copy-paste tables from property schedules, and reconcile contradictory coverage summaries. Then comes the hunt for missing COPE, ded/limit tables, and peril-specific sublimits.
Typical manual workflow:
- Collect SOVs, declarations pages, coverage summaries, endorsement lists, and reinsurance submissions via email and portal uploads.
- Standardize headings and column names by hand; re-key fields like TIV, limits, deductibles, occupancy, and construction where needed.
- Google for addresses that fail to geocode, reconcile suite numbers, PO boxes, intersections, and rural route designations.
- Split multi-risk entries into separate rows; backfill peril tags (wind, flood, earthquake, wildfire, hail, storm surge) from policy language.
- Run records through a geocoder; QC coordinate bias and rooftop vs. parcel centroids.
- Build a shapefile or GeoJSON to visualize clusters and accumulation; export CSVs to feed modeling platforms.
- Re-iterate when a new endorsement arrives or the broker emails a “final-final” schedule two hours before the cat committee meets.
This is painstaking and slow. It introduces human error at exactly the worst time — right before pricing, capacity, or renewal deadlines. It also diverts modelers from the work that matters: analyzing hazard interactions, portfolio accumulations, and treaty structures.
AI for Catastrophe Exposure Analysis Requires More Than OCR
Basic OCR can’t solve these pain points. The problem isn’t just reading text; it’s interpreting insurance-specific context buried across hundreds of pages, then assembling it into reliable, standardized, model-ready data. In other words, web scraping is about location; document scraping is about inference. For a deeper view into why this difference matters, see Nomad Data’s article, Beyond Extraction: Why Document Scraping Isn’t Just Web Scraping for PDFs.
Catastrophe exposure analysis compounds that complexity. Deductibles may be specified per building, per location, per occurrence, or as percentage-of-value with minimums and maximums that vary by peril. Sublimits, aggregates, and occurrence caps often live in coverage summaries or endorsement riders, not in the main schedule. Marine schedules may use non-standard references — a terminal nickname, a berth number, or a voyage leg — that must be mapped to a physical footprint before any model can run. The AI has to read like a seasoned cat modeler and apply consistent rules across an inconsistent document universe.
From Documents to Decisions: How Doc Chat Automates Cat Exposure Reviews
Doc Chat applies a suite of insurance-tuned agents to your document stack and delivers clean, geocoded, model-ready exposure data — fast. It is specifically designed to extract locations from policy schedules, standardize them, and automate geocoding for insurance policies using your chosen geocoding vendor or internal service. Then it assembles the geospatial outputs modelers and reinsurance teams rely on.
What Doc Chat Ingests
- Property schedules and Statements of Values (SOVs) across spreadsheets, PDFs, and scanned attachments
- Declarations pages, coverage summaries, endorsements, binders, subjectivities
- Reinsurance submissions and exposure bordereaux
- Marine cargo, hull, and terminal schedules; voyage manifests; terminal maps and UN/LOCODE references
- Engineering/inspection reports with COPE detail (roof age, roof geometry, fire protection, brush clearance)
What Doc Chat Extracts and Normalizes
- Location identifiers: full address, city, state/province, postal code, country; for marine: port/terminal, berth, yard, and vessel/IMO
- Coordinates: latitude/longitude, precision flag (rooftop, parcel, street centroid), geocoder confidence
- COPE: construction type, occupancy, protection class, number of stories, year built/retrofit, secondary modifiers
- Values and limits: TIV, blanket limits, occurrence/aggregate sublimits, peril-specific limits and deductibles
- Coverage nuances: waiting periods, percentage deductibles with min/max, special territories or distance-to-coast clauses
- Associations: policy number, insured name, location ID, building IDs, risk groupings for aggregation
Geocoding and Geospatial Reporting
Doc Chat connects to your preferred geocoder via API (or uses an internal service) to convert normalized addresses and marine references into reliable coordinates. The system marks confidence levels and provides exception queues for addresses needing human attention (e.g., ambiguous rural routes, intersections, or terminal nicknames). It then produces geospatial outputs you can use immediately:
- Cleaned, deduplicated SOV with coordinates and quality flags
- GeoJSON/Shapefile/CSV for mapping and model ingestion
- Accumulation heatmaps and proximity analyses (e.g., distance to coastline, floodplain overlays via your GIS layers)
- Peril-tagged rollups, AAL/PML input files, and treaty exhibits aligned to your modeling platform templates
Because Doc Chat is designed for real insurance work, you can ask it questions like, “List all locations within 1 mile of the coastline with TIV > $10M and wind deductible < 2%,” or “Show me all terminal accumulations with cargo and hull in the same UN/LOCODE.” It returns summarized answers with page-level citations and links back to the source documents for instant verification.
Special Focus: Marine and Specialty Accumulations
In Specialty Lines & Marine, accumulation analysis depends on translating operational references into mappable exposure. Doc Chat understands the language of terminals and voyages, so “Berth 7, South Wharf” and “Yard D, Gate 3” become coordinates. It pairs reinsurance submission exhibits with cargo/hull schedules and maps vessels by IMO to their last-known or intended berth to create time-bound exposure snapshots. This is especially valuable when reinsurers ask for port-level accumulation breakdowns with peril tags (wind, surge, quake) ahead of treaty placement.
Doc Chat’s specialty handling includes:
- Port and terminal normalization using UN/LOCODE and your internal location dictionaries
- Voyage parsing for in-transit cargo exposures mapped to legs and ETAs
- Time-sliced accumulation reporting (at 6/12/24-hour windows) to align with reinsurer exhibits
- Terminal stacking logic and co-located asset identification (hull + cargo + terminal property)
From Policy Schedules to Geospatial Reports in Minutes
For Property & Homeowners and Specialty Lines & Marine, Doc Chat converts unstructured documents into decision-ready geospatial outputs in minutes, not days. Typical outputs include:
- Standardized SOV with complete COPE, peril-specific deductibles/limits, and coordinates
- Peril accumulation dashboards by county/CRESTA/zone/port/terminal
- Distance-to-coast distributions and threshold exceedance counts
- GeoJSON/Shapefile layers for immediate visualization in GIS tools
- Model-ingestion templates aligned to RMS, Verisk/Touchstone, and AIR file formats
- Reinsurance-ready exhibits: per-occurrence and aggregate views with treaty-specific columns
You keep full control of your modeling and hazard layers; Doc Chat accelerates and improves the “documents-to-data” pipeline and packages outputs the way your team and counterparties expect to see them.
What Changes When You Automate Geocoding for Insurance Policies
When a catastrophe modeler plugs Doc Chat into the submission workflow, several things happen immediately:
- Cycle time collapses. A 5,000-row schedule that used to take days to standardize and geocode is ready in under an hour, often minutes.
- Accuracy improves. Coordinates come with confidence flags. Ambiguous or low-confidence entries are queued for quick human follow-up, eliminating silent location drift that distorts accumulations.
- Coverage clarity increases. Deductibles and sublimits are pulled from coverage summaries and endorsements, linked back to source citations so underwriters and reinsurers can validate quickly.
- Negotiation improves. Reinsurance partners get consistent, defensible exhibits faster — often the difference between competing terms.
This is why leading carriers discover that the “simple” data-entry part of exposure work is an outsized opportunity for automation. For a broader perspective on this theme, see AI's Untapped Goldmine: Automating Data Entry.
How Doc Chat Works Under the Hood
Doc Chat isn’t a generic summarizer. It’s a set of insurance-trained, purpose-built agents optimized for volume, complexity, and auditability:
- Volume: Ingest entire exposure and policy files — thousands of pages or tens of thousands of rows — without adding headcount. Reviews move from days to minutes.
- Complexity: Extract peril-specific terms buried in endorsements and summaries, apply rules for min/max percentage deductibles, and flag special territories or coinsurance that affect loss modeling.
- The Nomad Process: We train Doc Chat on your playbooks, SOV templates, and preferred modeling formats, delivering a solution tailored to your workflows.
- Real-time Q&A: Ask natural-language questions across the entire submission set and get instant, citation-backed answers.
- Thorough & complete: Doc Chat surfaces every reference to coverage, liability, or damages relevant to exposure modeling — so nothing critical slips through.
Because catastrophe teams require defensibility, every extracted field carries lineage back to the page and paragraph it came from, making audits and reinsurance discussions faster and less contentious.
Business Impact: Time, Cost, Accuracy, and Negotiation Power
Implementing Doc Chat in catastrophe workflows reliably produces quantifiable gains:
- Time savings: Reduce schedule standardization and geocoding from days to minutes. Portfolio accumulation refreshes that once consumed a week drop to half a day — including QC and exception handling.
- Cost reduction: Fewer manual touchpoints, less overtime, and the ability to scale to seasonal spikes without temporary staffing.
- Accuracy improvements: Consistent extraction of peril terms, deductibles, and sublimits, with geocode confidence and exception queues that reduce silent biases in accumulation.
- Better reinsurance outcomes: Data-defensible exposures, delivered faster, strengthen negotiating leverage and minimize friction with treaty partners.
- Happier teams: Cat modelers spend time analyzing hazard and portfolio dynamics instead of wrangling documents and addresses.
These outcomes are consistent with the broader transformation we’ve seen across insurance operations — where AI alleviates document bottlenecks and unlocks higher-value work. For an example of how speed and explainability drive adoption in complex claims contexts (and by analogy, complex exposure contexts), see Reimagining Insurance Claims Management: GAIG Accelerates Complex Claims with AI.

Case Vignette: From Three Days to Thirty Minutes
A cat modeling team supporting both Property & Homeowners and Marine lines faced a common crunch: a 4,800-location homeowners schedule and a 600-line marine terminal & cargo submission arriving within 48 hours of a treaty meeting. Historically, standardizing the homeowner schedule, fixing addresses, and geocoding took two days. Marine exposures introduced another day of mapping terminal nicknames to coordinates and pairing cargo with time windows.
With Doc Chat, the team processed both files in ~30 minutes of system time and ~35 minutes of QC. Doc Chat:
- Extracted address, TIV, peril ded/limits from scattered endorsements and summaries
- Geocoded to rooftop or parcel with confidence flags and exception queues
- Mapped terminal nicknames to UN/LOCODE and berth footprints
- Produced GeoJSON layers and RMS/AIR-ready CSVs
The treaty analytics team had defensible exhibits, complete with page-level citations back to source documents, enabling a data-first negotiation that won improved terms.
Addressing Edge Cases and Real-World Messiness
Catastrophe exposure work is full of difficult records. Doc Chat handles these scenarios with explicit logic and transparent exceptions:
- Ambiguous addresses: Multiple candidate geocodes are ranked with confidence scores; low-confidence records route to an exception queue for review.
- PO boxes and rural routes: Doc Chat issues a “needs-physical-address” alert, citing the page reference. When available, it leverages context (e.g., inspection reports) to resolve a physical location.
- Terminal nicknames and voyage legs: Mapped against your internal dictionaries and UN/LOCODE references; Doc Chat flags unmapped names for quick human confirmation.
- Peril-specific terms: Percentage deductibles with min/max and special territories are calculated and normalized per your rules, with citations.
- Mixed units and currencies: Automatically standardized to your modeling defaults with original-unit retention for audit.
Explainability and Audit-Readiness
Every extracted value contains a breadcrumb trail back to the source page and paragraph. That means modelers, underwriters, actuaries, and reinsurers can validate quickly — without re-reading hundreds of pages. When exposure exhibits travel to treaty partners, Doc Chat’s citations reduce negotiation friction. This “show your work” approach is core to adoption and mirrors the explainability standard covered in our claims transformation work: Reimagining Claims Processing Through AI Transformation.
Security, Compliance, and Data Governance
Doc Chat is designed for insurers’ security needs: SOC 2 Type II controls, document-level access management, and full audit trails across ingestion, extraction, and export. Outputs can be restricted to internal networks or delivered via secure integrations to your data lake, modeling platform, or GIS server. Page-linked citations allow compliance and audit teams to verify every field.
Frequently Asked Questions from Catastrophe Modelers
Can Doc Chat really extract locations from policy schedules at scale?
Yes. Doc Chat ingests entire files — thousands of pages or tens of thousands of rows — and standardizes inconsistent schedules. It ties each extracted value to a citation in the source property schedule, declarations page, or coverage summary so you can verify instantly.
Does Doc Chat automate geocoding for insurance policies?
Yes. Doc Chat integrates with your geocoder via API or uses a Nomad-provided service. It records geocode precision and confidence, routes low-confidence records to exception queues, and preserves original input for full traceability.
What about marine terminals, vessels, and port accumulations?
Doc Chat normalizes terminals using UN/LOCODE and your internal dictionaries, maps vessel references via IMO numbers, and builds time-sliced accumulation views for Specialty Lines & Marine reinsurance exhibits.
How long does implementation take?
Most teams are live in 1–2 weeks. We start with drag-and-drop pilots, then connect your geocoder, define outputs, and encode your peril rules. No data science effort required from your team.
Can Doc Chat export to my modeling platform?
Yes. We generate CSV templates aligned to your RMS, Verisk/Touchstone, or AIR import formats, alongside GeoJSON/Shapefile for GIS. We follow your schemas and naming conventions.
How do you handle ongoing changes — new endorsements or updated schedules?
Doc Chat watches for updates, re-runs extraction and geocoding, and refreshes outputs. Change logs highlight what moved so modelers can re-run only what’s necessary.
Strategic Payoffs for Reinsurance Negotiations
At renewal, speed and defensibility win. Doc Chat equips catastrophe modelers and reinsurance analysts with:
- Faster submissions: Complete, clean, geocoded exposures packaged in reinsurer-friendly exhibits.
- Transparent support: Page-linked citations that resolve questions on the spot.
- Scenario flexibility: Rapidly re-cut accumulations by geography, peril, or treaty term to evaluate options in real time.
- Better outcomes: When data arrives fast and verified, pricing and terms typically improve.
The Bigger Picture: From Bottlenecks to Breakthroughs
The document-to-data pipeline has historically throttled catastrophe analysis. With modern, insurance-specific AI, that constraint falls away. Modelers can interrogate exposures instead of cleaning them. Underwriters can press ahead with confidence in modeled results. Reinsurance teams can negotiate on facts, not approximations.
This shift mirrors what we’ve detailed across insurance: when you eliminate the manual friction of document work, everything else accelerates. For a broader perspective on the paradigm shift in high-volume document review, see The End of Medical File Review Bottlenecks — the principle is the same, even if the domain differs.
