数据大屏可视化 项目中经常需要渲染echarts地图，为了不同城市快速实现，将不同城市的echarts地图效果整理出来，今天为大家整理陇南市礼县echarts地图和threejs地图效果实例。地图基于geoJson数据绘制。
礼县，隶属 甘肃省 陇南市，地处甘肃省东南部，陇南市北部，东邻天水秦州区、西和县，西接宕昌、岷县，南连陇南市武都区，北与武山、甘谷县接壤。全县面积4299.92平方千米。截至2020年11月1日零时，礼县常住人口424135人。
echarts陇南市礼县geoJson地图点击地图获取经纬度
echarts地图渲染后,有时候会需要点击后获取到经纬度信息,通过经纬度信息来查询一些内容,这里我们可以通过convertFromPixel来获取经纬度.
echarts陇南市礼县geoJson地图 tooltip轮播
echarts地图实现类似tooltip轮播效果,通过effectScatter实现浮窗,并通过定时修改effectScatter的data来实现浮窗的移动.
echarts陇南市礼县geoJson地图根据经纬度显示自定义html弹窗
echarts地图我们可以通过像素坐标来将我们自定义的html弹窗定位到echarts地图指定位置,如果是固定的宽高的话,这没什么问题直接定位就可以了,如果是自适应宽高的地图我们可能没办法控制精度,我们可以使用经纬度来控制,当echarts地图渲染完成以后,我们可以通过convertToPixel将经纬度转为像素坐标,然后再渲染自定义弹窗,这样精度就比较准确了,而且也不会因为窗体宽高变化而导致弹窗出现偏移.
threejs陇南市礼县geoJson地图3d地图添加旋转棱锥
通过threejs绘制3d地图并在指定经纬度上添加带波纹效果不停旋转的棱锥效果实例,如果想系统的学习threejs的话，可以观看threejs视频教程 WebGL/Three.js前端高薪3D可视化

threejs陇南市礼县geoJson地图3d地图添加金色效果
通过threejs绘制3d地图使用outlinePass实现金色描边效果,并通过edgeStrength增加强度,让描边更清晰
