一、项目背景
项目采用：vue3+java+Arco Design+SpringBoot+OpenStreetMap 数据的地图切片服务。我们的项目会上报或者手动添加多台中转台，中转台有属性：经度、纬度、海拔。我们想在在线/离线地图上展示设备信息。
二、页面效果
电子地图
中转台RSSI地图
点击工具，测距
点击工具，开启中转台覆盖范围
三、代码

4.src/stores/index.js Vuex存储属性
/*** @Name：* @Author：贾志博* @description：*/
import {defineStore} from "pinia";
import {ref} from 'vue'export const useStore = defineStore('main', () => {const mode = ref(0)const setMode = (modeVal) => {mode.value = modeVal}const getMode = () => {return mode.value}const openMenuItem = ref([]);const setOpenMenuItemFunction = (modeVal) => {openMenuItem.value = modeVal}const getOpenMenuItemFunction = () => {return openMenuItem}const selectedMenuItemKey = ref(null);const setSelectedMenuItemKeyFunction = (modeVal) => {selectedMenuItemKey.value = modeVal}const getSelectedMenuItemKeyFunction = () => {return selectedMenuItemKey}const selectedMenuKey = ref("");const setSelectedMenuKeyFunction = (modeVal) => {selectedMenuKey.value = modeVal}const getSelectedMenuKeyFunction = () => {return selectedMenuKey}const hasAuth = ref(false)const routes = ref([])const popoverVisible = ref(false);const popoverPosition = ref({ top: 0, left: 0 });const selectTopoNode = ref(null)const websocketRepeaterList = ref([])return {getMode,setMode,setSelectedMenuKeyFunction,getSelectedMenuKeyFunction,setSelectedMenuItemKeyFunction,getSelectedMenuItemKeyFunction,setOpenMenuItemFunction,getOpenMenuItemFunction,hasAuth,routes,popoverVisible,popoverPosition,selectTopoNode,websocketRepeaterList,}
})四、注意点
注意点1：地图分在线地图/离线地图，离线地图需要上传瓦片地图。
注意点2：在线地图采用，在线地图服务：https://a.tile.geofabrik.de/
注意点3：使用OpenStreetMap地图步骤
要获取类似于 https://a.tile.geofabrik.de/15173cf79060ee4a66573954f6017ab0/{z}/{x}/{y}.png 的地图切片 URL，您可以按照以下步骤进行：
选择地图服务提供商
您可以选择不同的地图服务提供商，Geofabrik 是一个提供基于 OpenStreetMap 数据的切片服务的选项。其他常见的提供商包括：
- OpenStreetMap: https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png
- Mapbox: 需要注册并获取 API 密钥。
- Carto: 需要注册并获取 API 密钥。
-
确定区域和数据集
如果您希望使用 Geofabrik 的服务，您需要确定您想要的地图区域。Geofabrik 提供了不同区域的切片，您可以在其网站上找到这些区域。通常，URL 中的标识符（例如 15173cf79060ee4a66573954f6017ab0）对应于特定的区域。 -
获取区域的切片 URL，访问 Geofabrik 网站
- 访问 Geofabrik 的切片服务页面:
- 前往 Geofabrik 网站。
- 选择区域:
- 在网站上，您可以选择特定的区域（如国家或城市）以获取相应的切片服务。
- 查找切片服务的 URL:
- 在选择的区域页面上，您通常可以找到用于该区域的切片服务 URL，类似于 https://a.tile.geofabrik.de/{区域标识}/{z}/{x}/{y}.png。
其他注意事项
- 使用条款: 在使用任何地图切片服务之前，请确保遵循其使用条款和条件，尤其是在商业应用中。
- API 密钥: 某些地图服务（如 Mapbox 和 Carto）需要您注册并获取 API 密钥才能使用其服务。
通过上述步骤，您可以获取并使用类似于 https://a.tile.geofabrik.de/15173cf79060ee4a66573954f6017ab0/{z}/{x}/{y}.png 的地图切片 URL。
注意点4：地图下方会实时显示鼠标的经纬度信息。
注意点5：地图右下角还有3个小工具：居中显示、测距、开启中转台覆盖范围
- 居中显示：未开发
- 测距：已开发,
- 开启中转台覆盖范围：这个是用户会配置颜色范围
操作手册中有详细介绍
注意点6：由于代码比较乱，这里详细介绍下具体使用。
电子地图页面显示
<div id="electronic_map"></div>import {onMounted, ref} from "vue";
import {LeafletMap} from "@/views/pages/_class/Map";const mapClass = ref(new LeafletMap())
const deviceManageList = ref([])
const isChecked = ref(true);const changeOnlineMap = (val) => {mapClass.value.changeOnlineMap(val)
}onMounted(async () => {mapClass.value.initMap('electronic_map', deviceManageList.value)mapClass.value.handleAllMarkerInMap(deviceManageList.value)changeOnlineMap(true);
})
右下角工具
<div class="search-in-map-br"><a-tooltip :content="$t(queryColumnValue[25])" position="left"><div class="btn-item"><img :src="centerImg" /></div></a-tooltip><a-tooltip :content="$t(queryColumnValue[26])" position="left"><divclass="btn-item":class="{ active: drawDistanceSwitch }"@click="drawDistanceSwitchChange"><img :src="distanceImg" /></div></a-tooltip><a-tooltip :content="$t(queryColumnValue[27])" position="left"><div class="btn-item":class="{ active: rangeFlag }"@click="rangeClick"><img :src="coverageImg" /></div></a-tooltip>
</div>import centerImg from "@/assets/img/center.png";
import distanceImg from "@/assets/img/distance.png";
import coverageImg from "@/assets/img/coverage.png";const drawDistanceSwitch = ref(false);
const rangeFlag = ref(false)const drawDistanceSwitchChange = () => {drawDistanceSwitch.value = !drawDistanceSwitch.value;if (drawDistanceSwitch.value) {mapClass.value.openDrawDistance();} else {mapClass.value.closeDrawDistance();}
};const rangeClick = () => {if (rangeFlag.value) {mapClass.value.closeCoverageRange()} else {mapClass.value.openCoverageRange()}rangeFlag.value = !rangeFlag.value
}
