Geovisto
TypeScript mapping library for generic geospatial data visualization based on Leaflet.
This repository is a snapshot of Geoviosto core derived from the development repository: geovisto/geovisto-map.
Usage
import {
Geovisto
} from 'geovisto';
import 'geovisto/dist/index.css';
// ,,,
// create instance of map with given props
const map = Geovisto.createMap({
id: "my-geovisto-map",
data: Geovisto.getMapDataManagerFactory().json([
// list of data records (JSON structures)
// ...
]),
geoData: Geovisto.getGeoDataManager([
Geovisto.getGeoDataFactory().geojson("world polygons", {
// GeoJSON definition
// ...
}),
// other geographic data
// ...
]),
globals?: { // props of Leaflet-based map
zoom: number,
mapCenter: {
lat: number,
lng: number
},
mapStructure: {
maxZoom: number,
maxBounds: [[number, number], [number, number]]
}
},
templates?: Geovisto.createMapToolsManager([
// instances of Geovisto tools (extensions)
// these tools will be used as templates if new instance of tool needs to be created in the future
// ...
]),
tools?: Geovisto.createMapToolsManager([
// instances of Geovisto tools (extensions) which will be directly used in the map
// ...
])
});
// rendering of the map
map.draw(Geovisto.getMapConfigManagerFactory().default({
// initial settings of the map can be overriden by the map config - JSON structure providing user settings
zoom?: number,
mapCenter?: { lat: number, lng: number },
mapStructure?: { maxZoom: number, maxBounds: [[ number, number ],[ number, number ]] },
tools?: [
// config of Geovisto tools (extensions) used in the map
]
}));
// the map can be re-rendered
map.redraw(Geovisto.getMapConfigManagerFactory().default({ /* ... config ... */}), this.getProps([ /* ... data ... */]));
// current state of the map can be exported in the JSON format (map config)
const config = map.export();Demo
Installation
