geolibre

GeoLibre in Jupyter: the full GeoLibre GIS app as an anywidget, with a leafmap-style Python API.

The widget embeds the complete GeoLibre app (menus, panels, processing tools) inside a notebook cell. State syncs both ways through a single .geolibre.json project, so data you add from Python appears in the UI, and edits you make in the UI are readable back from Python.

Install

pip install geolibre

Or with conda from conda-forge:

conda install -c conda-forge geolibre

Quickstart

from geolibre import Map

m = Map(center=(-100, 40), zoom=4)
m.add_geojson("https://example.com/data.geojson", name="Data")
m

Add more data and drive the view:

m.add_tile_layer(
    "https://tile.openstreetmap.org/{z}/{x}/{y}.png",
    name="OpenStreetMap",
    attribution="(c) OpenStreetMap contributors",
)
m.add_cog("https://example.com/dem.tif", name="DEM", colormap="terrain")
m.add_basemap("dark")
m.set_center(-120, 47, zoom=8)

Round-trip the project:

m.save_project("my-map.geolibre.json")

m2 = Map()
m2.load_project("my-map.geolibre.json")

# Read state edited in the UI (e.g. after panning/zooming):
m.to_project()["mapView"]["center"]

API

Method	Description
Map(center, zoom, basemap=, height=, layout=, theme=)	Create a map. layout is "embed", "full", or "maponly".
add_geojson(data, name=, **style)	Add GeoJSON (dict, path, URL, JSON, or GeoDataFrame).
add_vector(data, name=, render_mode=, data_format=, source_layer=, **style)	Add a vector dataset from a URL (GeoParquet, FlatGeobuf, zipped Shapefile, GeoJSON) or a local file (read via GeoPandas, inlined).
add_geoparquet / add_flatgeobuf / add_shp (data, name=, **style)	Format-specific wrappers over add_vector.
add_vector_tiles(url, name=, source_layers=, source_layer=, **style)	Add vector tiles from a TileJSON endpoint.
add_pmtiles(url, name=, tile_type=, source_layers=, **style)	Add a PMTiles archive (vector or raster).
add_tile_layer(url, name=, tile_size=, attribution=)	Add a raster XYZ tile layer.
add_wms(endpoint, layers, name=, styles=, image_format=, transparent=, tile_size=, **style)	Add a WMS (GetMap) tiled raster layer.
add_wmts(url, name=, tile_size=, **style)	Add a WMTS tile URL template.
add_wfs(endpoint, type_name, name=, version=, output_format=, srs_name=, max_features=, **style)	Add a WFS layer (GeoJSON, fetched and inlined).
add_cog(url, name=, bands=, colormap=, rescale=)	Add a Cloud Optimized GeoTIFF.
add_raster(url, name=, bands=, colormap=, rescale=)	Add a raster (alias of add_cog).
add_3d_tiles(url, name=, altitude_offset=, request_headers=, **style)	Add a 3D Tiles tileset.json.
add_video(urls, coordinates, name=, **style)	Add a georeferenced video (four [lng, lat] corners).
add_basemap(basemap)	Set the background basemap.
set_center(lng, lat, zoom=None)	Center (and optionally zoom) the map.
set_center_zoom(lng, lat, zoom=None)	Alias of set_center (leafmap compatibility).
remove_layer(layer_id) / clear_layers()	Remove layers.
to_project() / load_project(src) / save_project(path)	Project I/O.

Notes

• The bundled app is served from a localhost HTTP server, so the interactive widget works in local Jupyter and VS Code directly. Google Colab routes through its built-in port proxy automatically. On JupyterHub (including managed/shared hubs) the front-end tries two same-origin routes and uses whichever is live, so a host needs only one of them: the Jupyter Server extension bundled with geolibre at {base_url}geolibre/app/ (enabled automatically on pip install geolibre, but registered only after the Jupyter server restarts), and jupyter-server-proxy at {base_url}proxy/{port}/ (works in the running server with no restart where it is installed). On other remote servers (Binder, remote JupyterLab), pass Map(server_proxy=True) to use that same remote path; Map(server_proxy=False) forces the direct path.
• Optional extras: pip install geolibre[all] adds GeoPandas/Shapely support for add_geojson(geodataframe) and for reading local vector files (add_vector/add_geoparquet/add_flatgeobuf/add_shp), which the kernel reads and inlines as GeoJSON. Remote URLs for the same formats stream through the in-browser vector control and need no extras.
• add_geojson inlines file/URL data into the project (up to 50 MB), so a large dataset is held in memory and re-synced on every project update. For very large layers, prefer a tile or COG source (add_tile_layer/add_cog) the app fetches directly.
