Architectural Overview

Backend

The backend is composed of a set of stateless microservices that communicate over gRPC. Services include:

Tile Service – serves pre‑generated image tiles to clients
Metadata Service – provides layer descriptors and acquisition metadata
Analytics Service – executes computationally intensive tasks such as NDVI calculation
Auth Service – handles user authentication and token issuance

Stateful components, such as the user session manager, are stored in a distributed key‑value store that guarantees eventual consistency.

Frontend

The frontend architecture follows a component‑based model. Core components are:

GlobeRenderer – the WebGL canvas that displays the globe
LayerManager – controls the visibility and order of data layers
UIController – provides controls for camera manipulation and layer selection
EventBus – facilitates communication between components

State is managed using a Redux‑style store that ensures a single source of truth for the application.

Data Pipelines

Data ingestion follows an ETL (Extract‑Transform‑Load) approach. Raw imagery is extracted from satellites or suppliers, transformed into standardized formats, and loaded into the object store. A subsequent step generates tiles for each zoom level. The entire pipeline is orchestrated by a workflow manager that monitors progress and handles failures.

Security and Compliance

Security measures include:

Transport Layer Security (TLS) for all data in transit
Encrypted storage at rest using server‑side encryption
Fine‑grained access control enforced by the Auth Service
