Assessment

Every 360° scene we capture is analyzed against established methodologies—NPS Visual Resource Inventory, USDA erosion standards, River Access Planning Guidelines. The result is structured, queryable data for every single viewpoint: condition ratings, measurements, feature inventories, risk assessments, and recommendations.

The Scale of Data

A 10-mile trail captured at 50-foot intervals produces roughly 1,000 scenes. Each scene is a full 360° panorama—six cube faces covering every direction. Each face is analyzed independently, then synthesized into scene-level findings.

A single scene generates 50-100 discrete data points: condition grades, severity ratings, feature classifications, dimensional estimates, risk flags, recommendations. Multiply that across 1,000 scenes and you're looking at 50,000-100,000 individual observations for one trail.

This is documentation at a resolution that field crews can't match manually. Every culvert, every erosion feature, every accessibility barrier—located, classified, measured, and rated. Queryable. Exportable. Defensible.

Filter by condition rating to surface every Grade D or worse location. Query for active gully erosion. Map all scenes with ADA barriers. Export everything as GeoJSON for your GIS. The data structure is designed for action, not just reporting.

Per-Scene Output

Condition grades (A-F), severity ratings, dimensional estimates, feature classifications, risk flags, confidence scores, and prioritized recommendations with cost categories.

Six-Face Analysis

Front, right, back, left, up, down—each face assessed for relevant conditions. Directional findings (erosion on left bank, hazard ahead) preserved in the data.

Measurement Estimation

Known camera heights and reference objects enable dimensional estimates: rill depth, gully width, bank height, slope angles, affected area extent in meters.

Indexed & Searchable

Full-text search across all findings. Filter by grade, feature type, severity, or custom tags. Locate specific conditions across entire trail systems in seconds.

Putting Data to Work

Structured data is only valuable if it drives decisions. Scene-level assessment feeds directly into maintenance workflows, planning processes, compliance documentation, and funding applications.

Maintenance Prioritization

Sort all scenes by condition rating. Export a work list of every location graded D, E, or F with GPS coordinates, issue description, and estimated repair category.

  • Prioritized punch lists by severity
  • GPS coordinates for field crews
  • Photo documentation attached
  • Cost category estimates for budgeting

Grant Applications & Compliance

Quantified condition data strengthens funding requests. Before/after documentation for NPDES, 319 grants, RTP funds, and state programs.

  • Baseline condition documentation
  • Quantified deficiency counts
  • Progress tracking over time
  • Exportable reports for submissions

Capital Improvement Planning

Aggregate condition scores across trail systems to justify CIP budgets. Identify systemic issues. Plan multi-year improvement programs with data.

  • System-wide condition summaries
  • Segment-level scoring for prioritization
  • Cost projection inputs
  • Board/council presentation materials

Asset Management Integration

Feed scene data into existing asset management systems. Link conditions to specific trail segments. Track deterioration rates over time.

  • Segment-level condition scores
  • Deterioration trending
  • Lifecycle cost modeling inputs
  • Work order generation

Risk & Liability Management

Document known hazards systematically. Track response actions. Establish defensible records of condition awareness and remediation efforts.

  • Hazard inventory with timestamps
  • Response action documentation
  • Condition change tracking
  • Insurance and claims support

Accessibility Compliance

Identify ADA barriers across trail systems. Prioritize accessibility improvements. Document compliance efforts for Title II/III requirements.

  • Barrier identification by type
  • Surface and slope assessments
  • Improvement prioritization
  • Transition plan documentation

Post-Event Assessment

Rapid re-assessment after storms, floods, or fire. Compare pre/post conditions. Document damage for FEMA, insurance, or emergency funding.

  • Before/after comparison
  • Damage extent quantification
  • Emergency repair prioritization
  • Disaster assistance documentation

Contractor Scoping & Verification

Provide detailed specs for bid packages. Document conditions before work begins. Verify completed repairs against original assessments.

  • Detailed scope documentation
  • Pre-construction baselines
  • Post-construction verification
  • Contract compliance records

Field Verification Workflows

Push flagged locations to mobile devices. Field crews verify conditions, add notes, confirm or adjust ratings. Close the loop between remote assessment and ground truth.

  • Mobile-ready location lists
  • Side-by-side imagery comparison
  • Field notes and photo capture
  • Verification status tracking

Environmental Monitoring

Track erosion progression, vegetation changes, invasive species spread, and riparian conditions over time with repeat assessments.

  • Change detection between surveys
  • Erosion rate estimation
  • Vegetation recovery tracking
  • Long-term trend analysis

Public Reporting & Transparency

Share condition data with stakeholders and the public. Support bond measures with documented needs. Justify closures or reroutes with evidence.

  • Public-facing condition dashboards
  • Community meeting materials
  • Bond/levy support documentation
  • Trail closure justification

Planning & Design Input

Inform trail reroutes, new construction, and rehabilitation design. Identify problem areas before breaking ground. Avoid repeating past failures.

  • Problem area identification
  • Drainage pattern documentation
  • Existing condition baselines
  • Design constraint mapping
