UI SDK GeoJSON for geographic data structures

Unmaintained package

These packages (@terminusdb/terminusdb-documents-ui etc.) were last published December 2023 and are no longer actively maintained. The documentation is preserved for reference. Community contributions and pull requests are welcome.

GeoJSON Demo

The GeoJSON Playground is no longer available. The examples below show the expected behaviour of <FrameViewer/> with GeoJSON data types.

The GeoJSON Playground previously demonstrated <FrameViewer/> in create, edit or view mode.

Example

This example shows how to load a FeatureCollection into <FrameViewer/>.

Note: In View mode we display the map view of geoJSONs using react-leaflets under the hood.

Example: Python

import { FrameViewer } from '@terminusdb/terminusdb-documents-ui'

  return <FrameViewer
    frame={frame}                           // above defined frame          
    formData={{}}                           // formData will be empty
    mode={"Create"}                         // mode 
    type={"FeatureCollection"}/>           // type of document

GeoJSON Schema

Below is the schema for loading geoJSON into a TerminusDB data product.

Example: JSON
