geolibre-wasm (Python)
Run the geolibre-rust geospatial
tool suite (the whitebox_next_gen tools plus GeoLibre's own) from Python. The
tools are a single WebAssembly (WASI) module executed in-process via
wasmtime, so there is no
native install, no GDAL, and no server — just pip install.
This mirrors the JavaScript geolibre-wasm/tools API (list_tools,
list_manifests, run_tool), so the two stay in sync.
The import package is
geolibre_wasm(the distribution isgeolibre-wasm), matching the npm package name and avoiding a clash with the separategeolibreapplication package.
Install
pip install geolibre-wasm
On first use the runtime (geolibre-cli.wasm, ~20 MB) is downloaded from the
matching GitHub release and cached under ~/.cache/geolibre/. To use a local
copy instead, set GEOLIBRE_WASM=/path/to/geolibre-cli.wasm or pass
wasm_path= to any call.
Usage
Inputs are placed under /work; the tool reads/writes there and any new files
come back as bytes. Each input value may be bytes, an http(s) URL
to download, or a local file path -- the same for raster and vector inputs:
res = gl.run_tool(
"write_geoparquet",
args=["--input=/work/in.geojson", "--output=/work/out.parquet"],
input={"in.geojson": "https://example.com/data/cities.geojson"}, # fetched for you
)
This downloads the whole file (no HTTP range reads). Works for cog.tif,
data.parquet, data.fgb, data.geojson, etc.
Paths are sandboxed. Every path inside
argsrefers to the tool's/workfilesystem, not your host disk.inputfiles are placed at/work/<name>, andres.fileskeys are paths relative to/work. Do your ownopen()/write()against host paths (e.g./content/...on Colab) on the Python side, never insideargs.
import geolibre_wasm as gl
# Discover tools (each manifest carries a "source": "geolibre" | "whitebox")
tools = gl.list_tools()
manifests = gl.list_manifests()
# Raster: compute slope from a DEM
dem = open("dem.tif", "rb").read() # read from host disk
res = gl.run_tool(
"slope",
args=["--input=/work/dem.tif", "--output=/work/slope.tif", "--units=degrees"],
input={"dem.tif": dem}, # -> /work/dem.tif
)
assert res.exit_code == 0, res.stdout # surfaces tool errors
open("slope.tif", "wb").write(res.files["slope.tif"]) # key is relative to /work
# Reproject (warp) to a target EPSG
res = gl.run_tool(
"reproject_raster",
args=["--input=/work/dem.tif", "--output=/work/wgs84.tif", "--epsg=4326"],
input={"dem.tif": dem},
)
# Vector: GeoJSON -> GeoParquet (Hilbert-sorted, bbox covering, ZSTD by default)
gj = open("cities.geojson", "rb").read()
res = gl.run_tool(
"write_geoparquet",
args=["--input=/work/in.geojson", "--output=/work/out.parquet"],
input={"in.geojson": gj},
)
open("cities.parquet", "wb").write(res.files["out.parquet"])
Tools that write a directory tree (e.g. raster_to_tiles) return nested keys:
res = gl.run_tool(
"raster_to_tiles",
args=["--input=/work/dem.tif", "--output_dir=/work/tiles", "--min_zoom=16", "--max_zoom=18"],
input={"dem.tif": dem},
)
for path, data in res.files.items():
# e.g. "tiles/16/9559/32767.png"
...
