话不多说先看效果图 要实现的功能就是按照根据省份展示出各省上传的数据量 首先我们可以查看 mapboxgl官网有一个例子地址如下: https://docs.mapbox.com/mapbox-gl-js/example/cluster/ 可以复制过来直接查看是否有聚合图 是这样的之后我想把数据的颜色变得有些透明的颜色,将字体的颜色改成白色的 https://docs.mapbox.com/mapbox-gl-js/style-spec/#layers-circle 这个链接就是修改circle样式的, mapboxgl.accessToken = '<your access token here>';; var map = new mapboxgl.Map({ container: "map", style: "mapbox://styles/mapbox/streets-v11", center: [-65.017, -16.457], zoom: 5 }); map.on("load", function() { // 从GeoJSON数据添加一个新的源并设置“cluster”选项为true。GL-JS将把point_count属性添加到源数据中。 map.addSource("earthquakes", { type: "geojson", data: "https:/

问题 I would like to display the address on dynamics CRM using MapBox API, i have used Google API and it works perfectly, but now i would like to display it using map box.

只谈情不闲聊 提交于 2019-12-19 04:49:15
问题 I have a single GeoJSON object that contains over 2000+ features and each feature is part of one category (i.e. "Electrical", "Military", etc). There are a total of about 38 categories.

How to remove all layers and features from map?

青春壹個敷衍的年華 提交于 2019-12-17 20:06:03
问题 I am working on a map and I would like to remove all features from the map on a certain event. The features are in multiple layers which are plotted dynamically. Some of the code is: $.getJSON('distributor-companies', function (data) { var layers = []; $.each(data, function (i, item) { if (item.geojson != '') { layers[i] = L.mapbox.featureLayer().addTo(map); $.getJSON('/geojson/' + item.geojson, function (data) { layers[i].setGeoJSON(data); // Loop over the added layer layers[i].eachLayer

CentOS环境下geojson切片程序Tippecanoe安装

mapbox发布geojson数据时需要切片,切片工具是Tippecanoe。但该工具不支持Windows系统下安装,在 https://github.com/mapbox/tippecanoe 可找到该工具源码,同时,网络上提供了安装方法,见 https://blog.csdn.net/xinlingjun2007/article/details/80846826 在CentOS系统下,安装方法存在一些差异,会出现sqlite、zlib、C++等库缺失的情况。 针对这个问题,提出以下安装方法: 安装sqlite库 yum install sqlite-devel.x86_64 -y 安装编译工具 yum install -y gcc automake autoconf libtool make yum insyall -y gcc gcc-c++ 安装zlib yum install zlib-devel 安装Git yum install -y git 下载源文件 git clone https://github.com/mapbox/tippecanoe.git 开始安装: make make install 测试: tippecanoe -v 来源: CSDN 作者: BaiWeiGui 链接: https://blog.csdn.net/BaiWeiGui/article

Cannot find Mapbox Vector Tile URL for my Mapbox Style map

[亡魂溺海] 提交于 2019-12-14 03:49:38
问题 Does anyone know how to get the URL for a Mapbox vector tile map (aka a "style")? I can only get a style address that looks like this: mapbox://styles/myusername/r3411y10ngh4sh3tc3tc , but I am using a plugin that requires a URL to integrate Mapbox's Vector Tiles with Leaflet: https://github.com/SpatialServer/Leaflet.MapboxVectorTile/blob/master/docs/configuration.md I tried substituting the style address provided by Mapbox for the URL var config = { url: "mapbox://styles/myusername

Vue, Leaflet, Mapbox - error map container not found

柔情痞子 提交于 2019-12-14 03:08:36
问题 My understanding is that the error is due to the my code attempting to initialize the map before the HTML element is rendered. Supposedly, initializing the map as a var in mounted() should fix it. I tried the suggested fix in this post, but it is not working for me. I set my refs value in my HTML: <div class="map-container-column"> <div class="map banner-map" id="map" ref="myMap"></div> </div> And I declared my map variable in mounted as well. I tried using the suggested syntax of L.map(this.
