React-Geovisto

A library providing set of React components to easily configure Geospatial Data Visualization created with Geovisto toolkit.

Usage

const map = useRef(null);

const dataManager = useMemo(() => {
    return Geovisto.getMapDataManagerFactory().json([
        // list of data records (JSON structures)
        // ...
    ]);
}, []); 

const configManager = useMemo(() => {
    return Geovisto.getMapConfigManagerFactory().default({
        // initial configuration
    });
}, []); 

const geoDataManager = useMemo(() => {
    return Geovisto.getGeoDataManager([
        Geovisto.getGeoDataFactory().geojson("world polygons", {
            // GeoJSON definition
            // ...
        ),
        // other geographic data
        // ...
    ]);
}, []); 

const fragments = useMemo(() => {
    return [
        ['geovisto-selection-tool', new SidebarFragment({ enabled:true })]
        // other fragments definitions
        // ...
    ];
}, []);

const baseMap = useMemo(() => {
    return {
        url: 'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',
        maxZoom: 20,
        maxNativeZoom: 19
    };
}, []);
