L7
Large-scale WebGL-powered Geospatial data visualization analysis framework.
Powered by WebGL, the rendering technology of L7 supports fast and efficient rendering of big data, 2D/3D rendering, possible through calculation and analysis of spatial data by GPU Parallel Compu-ting.
L7 focuses on geographic data expressiveness๏ผinteraction and design of geographic visualization layers. The basemaps on the platform are powered by third-party services

๐ Highlight features of L7 2.0
-
๐ Data-driven Visualization
Layer visualization API design base Semiology of Graphics.
It supports rich map visualization types for a better insight on data.
-
๐ High performance rendering with 2D/3D effect Real-time and dynamic rendering with millions of spatial data.
-
๐ Simple and flexible data format
L7 supports a wide variety of data formats including CSV, JSON, geojson, among others, eliminating the need to run conversions ahead of time.
-
๐ Multi-basemap
For global users, Mapbox is easy to be embedded by a simple line of code.
Getting Started
๐ฆ Installation
npm install @antv/l7@beta
Init Map by L7 scene
import { Scene } from '@antv/l7';
import { Mapbox } from '@antv/l7-maps';
const scene = new Scene({
id: 'map',
map: new Mapbox({
style: 'light',
pitch: 0,
center: [107.054293, 35.246265],
zoom: 4.056,
}),
});Add Layer
import { PointLayer } from '@antv/l7';
const pointLayer = new PointLayer()
.source(data)
.shape('circle')
.size('mag', [1, 25])
.color('mag', ['#5B8FF9', '#5CCEA1'])
.style({
opacity: 0.3,
strokeWidth: 1,
});
scene.addLayer(pointLayer);
