量测分析

框架支持各类空间量测

量测支持

INFO

距离量测：空间-line，投影-project，地表-onground，椭球-elliptic

面积量测：投影-project，地表-onground，椭球-elliptic

其他量测：高差量测、三角量测、方位角量测和体积量测

代码实例

初始场景

let map: any
LarkExplorer.ready({
    baseUrl: './dist/resources/',
  }).then(initMap)

function initMap() {
  // 默认谷歌影像地图
  const baseImagery = LarkExplorer.BaseLayer.DefaultTdtImg
  // 默认全球地形
  const baseTerrain = LarkExplorer.BaseLayer.DefaultTerrain
  map = new LarkExplorer.Map('map', baseImagery, baseTerrain)
  initView()
}
function initView() {
  const status = {
    position: {
      x: -947707.6526854301,
      y: 5525655.629629169,
      z: 3043025.882299652,
    },
    hpr: {
      heading: 3.862207334800405,
      pitch: -0.3624409974692644,
      roll: 0.0001087727106403591,
    },
  }
  map.Navigation.flyToPos(status, 3)
}

距离量测

/**
 * 距离测量
 * @param type line：空间，project：投影，onground：地表，elliptic：椭球
 */
const distance = (type: string) => {
  map.SpecialAnalysis.Measurement.distance(type, (res: any) => {
    console.log('距离量测结果：', res)
  })
}

面积量测

/**
 * 面积测量
 * @param type project：投影，onground：地表，elliptic：椭球
 */
const area = (type: string) => {
  map.SpecialAnalysis.Measurement.area(type, (res: any) => {
    console.log('面积量测结果：', res)
  })
}

其他量测

const height = () => {
  map.SpecialAnalysis.Measurement.height((res: any) => {
    console.log('高差量测结果：', res)
  })
}
const angle = () => {
  map.SpecialAnalysis.Measurement.azimuth((res: any) => {
    console.log('方位角量测结果：', res)
  })
}
const triangle = () => {
  map.SpecialAnalysis.Measurement.triangle((res: any) => {
    console.log('三角量测结果：', res)
  })
}
const volume = () => {
  map.SpecialAnalysis.Measurement.volume((res: any) => {
    console.log('体积量测结果：', res)
  })
}

移除量测结果

const removeAll = () => {
  map.SpecialAnalysis.Measurement.removeAll()
}
