COMPARATIVE ANALYSIS AND CHANGE DETECTION
Visual Time Comparator and Work-Progress Verifier (Dual-View)
A tool for directly comparing orthophotos, inspection footage, and thermal audits over time (Time-Lapse & Split-Screen). Verify construction progress, the quality of warranty-defect remediation, and thermal-retrofit effectiveness.
Interactive Split-Screen: Baseline vs Current State
Upload a reference dataset (T0) and a dataset from a subsequent stage (T1), then use the precision slider to verify deviations, volume growth, or the elimination of structural defects.
Reference State (Before / Stage T0)
Drop an orthophoto file, RGB footage, or source thermal image
Formats: .JPG, .PNG, .WEBP (up to 50 MB)
Verified State (After / Stage T1)
Drop the as-built file, current state, or as-built thermal image
Formats: .JPG, .PNG, .WEBP (up to 50 MB)
Project Confidentiality Guarantee (Client-Side Processing)
Split-screen rendering happens 100% locally in your browser's memory. Files are never uploaded to any external server or archived in the cloud — the full integrity of your trade secrets and NDA clauses is preserved.
REAL-WORLD APPLICATIONS
What do engineers and site managers actually use it for?
Milestone Verification
Compare job-site orthophotos month over month. Check earthworks progress, steel structure assembly, and material stock levels without a site visit.
Thermal-Retrofit Effectiveness
Compare radiometric heat maps before and after insulation repair. Document the elimination of thermal bridges on facades and roof surfaces.
Defect Remediation Control
Precise confirmation that repair work has been carried out (e.g. roofing membrane repair, skylight sealing, concrete joint pointing) to an evidentiary standard.
Need cyclical investment monitoring with automated reporting?
Under a dedicated AeroPRO contract we run cyclical photogrammetric missions with 3–5 cm RTK repeatability. All comparison layers, orthophotos, and point clouds are published to your Client Portal.
