Example sources#

Public endpoints and thin fetch presets for testing host quirks — not a product catalogue. Prefer the presets in Quick start where they apply; use from_url for everything else. Stay polite: identifiable User-Agent where required, and do not raise concurrency past a host’s documented ceiling.

OpenStreetMap raster tiles (XYZ)#

  • Template: https://tile.openstreetmap.org/{z}/{x}/{y}.png

  • Prefer XYZConfig.for_openstreetmap(zoom=...).

  • OSMF wants an identifiable User-Agent and polite use — the preset applies fixed limits (max 2 in-flight, ~2 req/s, no AIMD).

  • Open data; include © OpenStreetMap contributors when displaying.

Environment Agency Lidar DTM (WCS)#

  • URL: https://environment.data.gov.uk/spatialdata/lidar-composite-digital-terrain-model-dtm-1m/wcs

  • CoverageId: 13787b9a-26a4-4775-8523-806d13af58fc__Lidar_Composite_Elevation_DTM_1m

  • Prefer WCSConfig.for_ea_dsp(...) with this coverage id.

  • The CoverageId comes from GetCapabilities (often UUID__LayerName) — never assume the URL path slug is the id.

  • Preset AIMD: start 8, ceiling 10, floor 4, ×0.75 pressure, sustained-403 circuit breaker. For county-scale cold mosaics, keep max_concurrent_requests ≤ 10.

NASA GIBS Blue Marble (XYZ)#

  • Template: https://gibs.earthdata.nasa.gov/wmts/epsg3857/best/BlueMarble_NextGeneration/default/GoogleMapsCompatible_Level8/{z}/{y}/{x}.jpeg

  • Path is {z}/{y}/{x} (row before col), not OSM {z}/{x}/{y}.

  • Use XYZConfig.from_url with that template. JPEG colour mosaics keep RGB bands (y, x, band).

  • Public; coordinate if you exceed roughly 1M tiles / 24h. Layer is hardcoded in the path — another GIBS product needs its own template from GetCapabilities.

USGS 3DEP elevation (WCS)#

  • URL: https://elevation.nationalmap.gov/arcgis/services/3DEPElevation/ImageServer/WCSServer

  • CoverageId: DEP3Elevation

  • Use WCSConfig.from_url(..., coverage_id="DEP3Elevation", crs=EPSG:3857) — no fetch preset.

  • DescribeCoverage supplies native CRS and subset axes (ArcGIS x/y in EPSG:3857). GetCoverage is often multipart/related; decode unwraps the GeoTIFF part.

Environment Agency Vegetation Object Model (WMS)#

  • URL: https://environment.data.gov.uk/spatialdata/vegetation-object-model/wms

  • Use WMSConfig.from_url(..., layers=...) — no fetch preset; thin GetMap adapter.

  • Layer id is year-suffixed (e.g. Vegetation_Object_Model_2022 from GetCapabilities — confirm the year).

  • Transparent GetMap PNG decodes to 4 bands (RGBA), not 3.

OS Maps API ZXY (needs key)#

  • Template: https://api.os.uk/maps/raster/v1/zxy/Road_3857/{z}/{x}/{y}.png?key=…

  • Useful for real HTTP 429 throttle behaviour. Attribution required. Do not commit keys.

Other XYZ (restricted)#

Google Satellite (http://mt0.google.com/vt/lyrs=s&hl=en&x={x}&y={y}&z={z}) can exercise XYZ wiring, but usage is restricted — prefer the open sources above for docs, demos, and production.
