Package Exports

@jupyterlab/geojson-extension

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@jupyterlab/geojson-extension) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

geojson-extension

A JupyterLab extension for rendering GeoJSON

demo

Prerequisites

JupyterLab ^0.30.0

Usage

To render GeoJSON output in IPython:

from IPython.display import GeoJSON

GeoJSON({
    "type": "Feature",
    "geometry": {
        "type": "Point",
        "coordinates": [-118.4563712, 34.0163116]
    }
})

To use a specific tileset:

GeoJSON(
    data={
        "type": "Feature",
        "geometry": {
            "type": "Point",
            "coordinates": [-118.4563712, 34.0163116]
        }
    }, url_template="https://api.tiles.mapbox.com/v4/{id}/{z}/{x}/{y}.png?access_token=[MAPBOX_ACCESS_TOKEN]", 
    layer_options={
        "id": "mapbox.streets",
        "attribution" : '&copy; <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a>'
    }
)

To render GeoJSON on Mars:

GeoJSON(
  data={
      "type": "Feature",
      "geometry": {
          "type": "Point",
          "coordinates": [11.8, -45.04]
      }
  }, url_template="http://s3-eu-west-1.amazonaws.com/whereonmars.cartodb.net/{basemap_id}/{z}/{x}/{y}.png", 
  layer_options={
      "basemap_id": "celestia_mars-shaded-16k_global",
      "attribution" : "Celestia/praesepe",
      "tms": True,
      "minZoom" : 0,
      "maxZoom" : 5
  }
)

To render a .geojson or .geo.json file, simply open it:

Install

jupyter labextension install @jupyterlab/geojson-extension

Development

# Clone the repo to your local environment
git clone https://github.com/jupyterlab/jupyter-renderers.git
cd jupyter-renderers
# Install dependencies
yarn install
# Build Typescript source
yarn run build
# Link your development version of the extension with JupyterLab
jupyter labextension link packages/geojson-extension
# Rebuild Typescript source after making changes
yarn run build
# Rebuild JupyterLab after making any changes
jupyter lab build

You can watch the jupyter-renderers directory and run JupyterLab in watch mode to watch for changes in the extension's source and automatically rebuild the extension and application.

# Run jupyterlab in watch mode in one terminal tab
jupyter lab --watch
# Watch the jupyter-renderers directory
yarn run watch

Uninstall

jupyter labextension uninstall @jupyterlab/geojson-extension
