OASIS: AI-Assisted Geospatial Analysis System | Technical Architecture and Workflow Record

OASIS is an AI-assisted geospatial analysis system designed for raster-based analytical workflows. Its architecture combines a user-facing frontend, a backend runtime, workspace data and artifact management, and bounded access to external model services for controlled analytical assistance.

This record presents the technical architecture and workflow logic of OASIS. It describes the system’s approach to request interpretation, metadata-aware planning, validation, execution control, artifact persistence, provenance, and downstream analytical reuse across its main modules.

The record includes a technical system overview, an interface-oriented frontend overview, and a short demonstration video.
