vue+openlayer实现轨迹路线3857
时间: 2023-05-10 12:01:23 浏览: 198
Vue开发框架与OpenLayers开源地图框架可以很好地结合,用于实现3857轨迹路线。要实现这个功能,可以遵循如下步骤:
1. 安装并导入Vue和OpenLayers相关库文件。
2. 准备地图底图,以及需要展示的轨迹数据,并通过Vue组件进行渲染。
3. 创建一个OpenLayers Map对象,并将其加入Vue实例中。在Map对象中,可以定义地图的中心点、缩放级别等参数,以及显示范围。
4. 创建一个OpenLayers Layer对象,并将其加入Map中。Layer对象可以用于管理和展示地图图层。
5. 创建一个OpenLayers Vector Layer对象,用于展示轨迹数据。在Vector Layer对象中,可以定义轨迹的样式、箭头指示等参数,以及数据的坐标系。
6. 将轨迹数据加入Vector Layer对象中,并执行绘制操作。可以通过OpenLayers提供的绘制工具,获取鼠标与地图交互的绘制事件,实现用户绘制轨迹的功能。
7. 如需展示轨迹的动画效果,可以使用OpenLayers提供的一些动画库(如Tween.js),根据轨迹坐标数据对轨迹进行移动和旋转等操作,从而实现轨迹的动态效果。
总之,Vue开发框架较为灵活,可以与各种地图框架及其相关库文件相结合,进行二次开发和扩展,从而实现各种地图应用及可视化效果。

vue+leaflet+element实现轨迹回放并且加可控制的进度条,用代码体现
可以使用Vue-leaflet和Vue2-leaflet-trackplayback库来实现轨迹回放,并使用Vue-slider-component来加入进度条控制。以下是代码示例:
<template>
<div id="map-container">
<l-map :zoom="zoom" :center="center">
<l-tile-layer :url="url"></l-tile-layer>
<l-track-playback :geojson="geojson" :options="options" ref="trackplayback"></l-track-playback>
<vue-slider :value="value" :min="0" :max="max" v-model="value" @change="handleSliderChange"></vue-slider>
</l-map>
</div>
</template>
<script>
import L from 'leaflet';
import 'leaflet/dist/leaflet.css';
import 'leaflet-trackplayback';
import 'vue-slider-component/theme/default.css';
import VueSlider from 'vue-slider-component';
export default {
name: 'map',
components: {
'l-map': L.Map,
'l-tile-layer': L.TileLayer,
'l-track-playback': L.TrackPlayback,
'vue-slider': VueSlider,
},
data() {
return {
zoom: 13,
center: [39.9, 116.4],
url: 'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',
geojson: {
type: 'Feature',

geometry: {
type: 'LineString',
coordinates: [[116.4, 39.9], [116.41, 39.91], [116.42, 39.92], [116.43, 39.93], [116.44, 39.94], [116.45, 39.95], [116.46, 39.96], [116.47, 39.97], [116.48, 39.98], [116.49, 39.99]]
}
},
options: {
markers: true,
autoplay: false,
playControl: true,
follow: true,
speed: 500,
markerOptions: {

max: 9,
};
},
methods: {
handleSliderChange(value) {
this.$refs.trackplayback.goTo(value);
