Autonomous Aerial Roof & Facet Estimator

Bridge the gap between raw geospatial data and field operations. Enter an address to synthesize high-resolution satellite geometry, Google Solar API roof pitch data, and computer vision into an instant, multi-angle surface breakdown.

Under the Hood: Multi-API Synthesis

Standard vision models cannot infer scale without reference anchors. We orchestrate raw building geometry, pitch vectors, and vision intelligence into a single automated pipeline.

01. INGEST

Places & Geocoding

Parses the raw address string into clean, normalized rooftop latitude and longitude coordinates, isolating the exact structural parcel.

Input: "123 Elm St..."
Output: lat, lng, place_id
02. GEOMETRY

Solar API Vectors

Pulls LiDAR-derived building footprint data: individual roof segment facets, pitch angles, azimuth bearings, and flat unadjusted square meterage.

Solar Data: pitchDegrees, azimuth
Facets: roofSegmentStats[]
03. VISION AI

Satellite & Street AI

Static multi-angle captures are passed to a vision model to detect material types (architectural vs 3-tab), obstructions (skylights, chimneys), and overhanging trees.

Detected: Shingle (Architectural)
Obstacles: 1 Chimney, 2 Vents
04. FORMULATION

Nuxt Trade Engine

Calculates sloped surface area multipliers, converts sq ft into trade squares (100 sq ft = 1 square), and applies customizable waste contingency margins.

Output: 28.4 Squares
Waste (+15%): 32.66 Squares
Security: Server-Side Proxied Endpoints (Zero Client API Key Leakage)
Response Latency: ~1.8s Aggregated Execution

Standard 2D aerial maps miss the slope angle. Calculating the true 3D pitch prevents the typical 10–18% material under-ordering deficit.

System Architecture & Standards

Why This Architecture Matters for Enterprise Tools

Building client-facing automated utilities requires more than stitching third-party APIs together. Here is why we architected this pipeline using Nuxt server engine proxies, zero-trust credential handling, and sub-second edge compute.

Server-Side Key Isolation & Zero-Trust

Commercial APIs like Google Solar and Maps charge per query. Exposing API keys directly in client-side JavaScript leaves them vulnerable to extraction, quota depletion, and unauthorized scraping.

  • All external calls routed through Nuxt Nitro server routes
  • Keys stored exclusively in server environment variables
  • Origin validation and CORS restrictions enforced

Edge Throttling & In-Memory Caching

Public utilities must balance instant accessibility with cost predictability. We integrate IP-based bucket throttling and transient caching for repeated geographic queries.

  • Token-bucket rate limiting per IP address
  • LRU cache for high-density parcel coordinate lookups
  • Prevents bill shocks and robotic query cycling

Nuxt & Vite Instant Hydration

Heavy single-page applications often choke under mathematical and visual rendering loads. Nuxt combines static shell generation with reactive Vue 3 composition modules.

  • Zero-bloat bundle size with tree-shaken SVG icons
  • Sub-second cold starts powered by Vite compilation
  • Reactive pitch multipliers recalculate instantly

Hybrid AI & Deterministic Math

AI models are prone to hallucinations when asked to perform raw geometric calculations. We treat AI as an observational classifier and rely on strict deterministic algorithms for measurements.

  • Vision AI classifies material & surface obstructions
  • Strict trigonometry calculates 3D pitch multipliers
  • Audit-ready outputs that contractors can verify
