EOxHub includes robust data visualization capabilities for both raster and vector data based primarily on eoapi. These are powered by titiler-pgstac and PgSTAC, which together enable dynamic tiling and rendering of STAC-compliant assets directly from storage based on pre-defined collection-level metadata fields.
It exposes a FastAPI based interface, supporting image formats such as PNG and JPEG, and standard interfaces like WMTS.
Future tutorials for eoAPI will become available in the tutorial section once possible.
Functionality¶
Catalog Your Data¶
PgSTAC is an optimized Postgres schema to index and search large-scale STAC collections.
Ingesting the existing STAC items to the database can be done in multiple ways:
- Manually via pypgstac as
pypgstac load items - Manually if transaction extension is enabled, then STAC data can be pushed to the API endpoint directly using POST/PUT requests.
Make it Searchable¶
This service utilizes stac-fastapi to publish and manage metadata describing their datasets, enabling machine-readable search, query, filter and cataloging across collections.
Visualize Raster Data¶
titiler-pgSTAC is a TiTiler extension that connects to pgSTAC to support large-scale dynamic mosaic tiling for visualizing STAC collections and items.
Visualize Vector Data¶
Utilizing tipg - Vector Tiling Service for OGC Features and OGC Tiles specifications.
