Open geospatial serving, made visible
One engine.
Seven visible paths.
Tellurion routes vector features, cloud-optimized rasters, multidimensional arrays and streamed 3D content, then exposes CQL2 filtering, STAC catalog views and server-rendered maps. This gallery puts a human interface in front of every machine endpoint.

Choose the data, then inspect the protocol.
Each entry begins with a visual experience and keeps the raw OGC API or 3D Tiles resource one deliberate step deeper.
Roads as queryable features and tiles.
A 5,603-feature OpenStreetMap sample served from GeoPackage through OGC API Features and Mapbox Vector Tiles.
Open the vector viewer → 02 / COG RASTERLand cover, read by range and rendered.
An attributed ESA WorldCover sample authored as a Cloud Optimized GeoTIFF and rendered into PNG tiles.
Open the raster viewer → 03 / ZARRTwo slices of one multidimensional field.
Deterministic Zarr v2 arrays with `[time, y, x]` shape, fixed leading indexes and a transparent limitation boundary.
Compare the Zarr slices → 04 / 3D TILESFootprints become streamable 3D.
Synthetic polygons move through vector tiling and extrusion into GLB content inside a 3D Tiles 1.1 tileset.
Orbit the 3D scene → 05 / CQL2Filter live features with a real expression.
A bounded query workbench sends CQL2 text to the GeoPackage driver and maps the returned GeoJSON.
Run a CQL2 query → 06 / STACTrace WorldCover from source to live tiles.
ESA WorldCover STAC → preserved COG and class metadata → Tellurion STAC/Features/raster Tiles.
Inspect the harvest path → 07 / MAPS + STYLESRender one bounded map on the server.
A CRS84 window becomes an 800 × 500 PNG, with a switch between the collection default and a named MapLibre style.
Request the rendered map →Evidence discipline
Show what works. State what it proves.
Versioned Tellurion 0.3.0 artifacts are checksum-verified. Generated fixtures are deterministic and dependency-light.
3D Tiles 1.1 is identified as an approved OGC Community Standard; draft-inspired API routes are not labelled conformant.
Demo code, Tellurion software, OpenStreetMap data and ESA WorldCover each retain their own terms and attribution.

This gallery connects current Tellurion work with the broader engineering path behind GeoID and years of open-source geospatial development.
