React Leaflet Maps with Shapefile Support

This example React application uses react-leaflet and shpjs npm packages to display a full-screen interactive map (like google maps, without geolocation, but for free) with a simple button to upload geospatial data files in zipped shapefile (.shp) spatial data format. The geospatial data are then displayed in an Overlay. At the moment, only a single Overlay is supported (cannot render multiple shapefiles). As a bonus, it shows a marker on the centre of the map, and displays the latitude/longitude of that marker. :P

Supports 30+ free Tile Layers, i.e. OpenStreetMap, Stamen, ESRI, Stadia, USGI, etc. Actually, the app includes an adapted copy of the Leaflet-providers configurations for various tiles providers. Fork it and edit the lib/TileProviders.js file to add your API keys, if you want to use one of the non-free tile providers (api key support not tested, though, you may have to hack it).

Try the live app and have fun!

Shapefiles (for testing)

• Examples: There are some zipped shapefile examples in the shapefile-examples folder

• World shapefile maps

  • Natural Earth - world maps
  • GADM

• USA: The US Census Bureau offers zipped shapefiles at this page (contains many state-based and national congressional district cartographic boundary data):

• EU: The European Environment Agency offers zipped shapefiles and other GIS data of European countries on this page (contains country borders and, where applicable, marine Exclusive Economic Zones):

• Country shapefile maps

  • GADM
  • Humanitarian Data Exchange

Available Scripts

The project was bootstrapped with Create React App.

In the project directory, you can run:

yarn start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

yarn test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

yarn build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

yarn eject

Note: this is a one-way operation. Once you eject, you can’t go back!

If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
