Hi, I'm Samuel Appiah Kubi 🌍🛰️

Incoming Copernicus Master in Digital Earth (GeoDSc track) | GeoAI & Advanced InSAR Engineer

I build production-grade, open-source Python frameworks at the intersection of spatial deep learning (GATs, PINNs) and physical Earth Observation invariants.

Core Deep-Tech Engines (Staged Release / Intensive Testing)

  • ps-gnn — DOI: 10.5281/zenodo.22706887 Re-engineering Persistent Scatterer (PS) target selection by reframing point cloud identification as spatial node classification via an 8-head Graph Attention Network (GAT). Status: Staged Release — Closed Beta

  • pyunwrap-insar — DOI: 10.5281/zenodo.22209219 A physics-informed neural network engine (AmbiguityNet) that resolves complex radar phase-unwrapping boundaries by enforcing discrete integer ambiguity matrices $K$ through straight-through estimator rounding layers. Status: Staged Release — Closed Beta

Ingestion & Production Pipelines

  • pygeofetch — DOI: 10.5281/zenodo.22087230 A programmatic federated data-access layer spanning 24 providers with built-in pre-download burst screening (PreflightGate) and a native, pure-Python Windows-compatible InSAR processing chain. Status: Stable — Public Production

  • pygeovision — DOI: 10.5281/zenodo.22258220 An enterprise-ready GeoAI engine supporting 49 automated task pipelines, chainable preprocessing analytics, and an audited model registry (Prithvi-EO-2.0, DINOv3) driven by an LLM-backed natural language query interface (GeoAgent). Status: Staged Release — Closed Beta

Scientific Validation Campaigns

  • Mexico City Subsidence Project End-to-end programmatic SBAS time-series analysis over a 502.5 GB / 67-scene Sentinel-1 SLC stack on a single machine. Mapped extreme urban subsidence vertical velocities up to −35.5 cm/year while preventing 360 GB of redundant downloads via intelligent orbital track pre-filtering.
