Malicious npm Packages Inject SSH Backdoors via Typosquatted Libraries
Socket’s threat research team has detected six malicious npm packages typosquatting popular libraries to insert SSH backdoors.
@dvgis/cesium-map
Advanced tools
Cesium 地图插件,用于添加国内各大地图厂商的地图
使用前引入 Cesium 框架,由于Cesium放弃了ImageryProvider部分属性,建议使用`viewer.imageryLayers.add`添加地图
NPM / YARN
npm install @dvgis/cesium-map
-----------------------------
yarn add @dvgis/cesium-map
import { AMapImageryProvider,BaiduImageryProvider, GeoVisImageryProvider } from '@dvgis/cesium-map'

高德地图
var options = {
style: 'img', // style: img、elec、cva
crs: 'WGS84' // 使用84坐标系,默认为:GCJ02
}
viewer.imageryLayers.add(new Cesium.ImageryLayer( new Cesium.AMapImageryProvider(options)))
百度地图
var options = {
style: 'normal', // style: img、vec、normal、dark
crs: 'WGS84' // 使用84坐标系,默认为:BD09
}
viewer.imageryLayers.add(new Cesium.ImageryLayer( new Cesium.BaiduImageryProvider(options)))
星图地图
var options = {
style: 'vec', //style: img、vec、ter, cia,cat,
key:'', // 需去相关地图厂商申请
format:'png' //format:png、webp(用于style为img)
}
viewer.imageryLayers.add(new Cesium.ImageryLayer( new Cesium.GeoVisImageryProvider(options)))
谷歌地图
var options = {
style: 'elec',//style: img、elec、ter,cva,img_cva
crs: 'WGS84' // 使用84坐标系,默认为:GCJ02, img除外
}
viewer.imageryLayers.add(new Cesium.ImageryLayer( new Cesium.GoogleImageryProvider(options)))
天地图
var options = {
style: 'vec', //style: vec、cva、img、cia、ter
key:'', // 需去相关地图厂商申请
}
viewer.imageryLayers.add(new Cesium.ImageryLayer( new Cesium.TdtImageryProvider(options)))
腾讯地图
var options = {
style: 1 //style: img、1:经典
}
viewer.imageryLayers.add(new Cesium.ImageryLayer( new Cesium.TencentImageryProvider(options)))
自定义地理平铺方案
根据瓦片的比例尺(degrees/px)
和切图原点重新计算瓦片行列号,最终会采用EPSG:4326
的瓦片计算规则平铺瓦片(可能会存在偏移)
var options = {
origin: [-180,90], //切图原点,默认为[-180,90]
zoomOffset: 0, //瓦片的0级对应Cesium的瓦片层级,值为: 0 - Cesium层级,若瓦片的0级对应Cesium的10级,则值为 0 - 10 = -10,同时在瓦片请求时{z}的数值替换时也需加上这个层级偏移值
tileSize: 256, //瓦片的大小,默认为256,即一张瓦片的大小为 256 * 256
resolutions:[],//瓦片每一层级分辨率
ellipsoid:Cesium.Ellipsoid.WGS84,// 平铺的椭球体,默认为 WGS84 椭球
rectangle:Cesium.Rectangle.MAX_VALUE,//平铺方案覆盖的矩形(以弧度表示)
}
viewer.imageryLayers.add(new Cesium.ImageryLayer(
new Cesium.TileCoordinatesImageryProvider({
tilingScheme: new Cesium.CustomGeographicTilingScheme(options),
})
))
自定义墨卡托平铺方案
根据瓦片的比例尺(meters/px)
和切图原点重新计算瓦片行列号,最终会采用EPSG:3857
的瓦片计算规则平铺瓦片(可能会存在偏移)
var options = {
origin: [-20037508.3427892, 20037508.3427892], //切图原点,默认为[-20037508.3427892, 20037508.3427892]
zoomOffset: 0, //瓦片的0级对应Cesium的瓦片层级,值为: 0 - Cesium层级,若瓦片的0级对应Cesium的10级,则值为 0 - 10 = -10,同时在瓦片请求时{z}的数值替换时也需加上这个层级偏移值
tileSize: 256, //瓦片的大小,默认为256,即一张瓦片的大小为 256 * 256
resolutions:[],//瓦片每一层级分辨率
ellipsoid:Cesium.Ellipsoid.WGS84,// 平铺的椭球体,默认为 WGS84 椭球
rectangleSouthwestInMeters: null,//切片方案覆盖的矩形的西南角,以米为单位。如果不指定该参数或矩形NortheastInMeters,则在经度方向上覆盖整个地球,在纬度方向上覆盖等距离,形成正方形投影
rectangleNortheastInMeters: null,//切片方案覆盖的矩形的东北角(以米为单位)。如果未指定此参数或矩形SouthwestInMeters,则在经度方向上覆盖整个地球,并在纬度方向上覆盖相等的距离,从而形成方形投影。
}
viewer.imageryLayers.add(new Cesium.ImageryLayer(
new Cesium.TileCoordinatesImageryProvider({
tilingScheme: new Cesium.CustomMercatorTilingScheme(options),
})
))
