easysnowdata.terrain.dem.search

easysnowdata.terrain.dem.search(aoi: Any = None, *, product: str | None = None, source: str | None = None, resolution: int | None = None, ellipsoidal: bool = False, **kwargs: Any) → GeoDataFrame

Return the DEM tiles covering aoi as a GeoDataFrame of STAC items.

Parameters:

• aoi – Any form easysnowdata.aoi.parse_aoi() accepts.

• product – Any product with a STAC route: "copernicus-dem" (default), "nasadem", "srtm", "3dep", "alos-dem" or "gedtm30".

• source – A STAC source of that product, the product’s default when None: "planetary-computer", "earth-search" (Copernicus) or "opentopography". Earth Engine routes have no tile search.

• resolution – The DEM resolution in metres where a product offers more than one (Copernicus 30/90, 3DEP 10/30).

• ellipsoidal – The WGS84-ellipsoid copy of SRTM or ALOS World 3D (source="opentopography" only).

• **kwargs – Passed to easysnowdata.providers.stac.search(). OpenTopography’s catalog is static, with no search API, so it takes none.

Returns:

geopandas.GeoDataFrame – One row per tile, filterable and accepted back by load().
