免费地图资源

地理信息系统（GIS）的搭建主要可分为两部分：1、三维地球引擎；2、基础数据图层。

CesiumEarth提供了可直接使用的三维地球引擎，因此只需准备基础数据图层，即可搭建属于自己的地理信息系统。

基础数据图包含地图数据、地形数据、专题数据等，其中以地图数据最为基础。

一：地图资源介绍

地图为地理信息系统的基础图层，主要为卫星影像、矢量图（街道图），描述地图要素中的基础空间框架，包括坐标系的参考对象等。

地图的选择途径很多，互联网上有多种公开可免费使用的地图资源，如天地图、高德地图、Bing地图、谷歌地图、ArcGIS地图等，

这里列举天地图、高德地图、ArcGIS地图三种：

1、天地图

提示：

天地图的使用需要向官网申请tk，本文中使用了CesiumEarth申请的临时tk，实际场景中推荐单独申请以免临时tk失效。
参数s为轮询地址，CesiumEarth中添加图层时可在前缀输入框中填写t0,t1,t2,t3,t4,t5,t6,t7。
地址中出现的x、y、z、TileMatrix、TileRow、TileCol为系统默认参数，连同{}，直接复制到CesiumEarth即可。

天地图提供WMTS及XYZ两种格式的地图服务，本文中主要以XYZ格式为主，XYZ格式在CesiumEarth中称之为自定义格式

卫星影像（XYZ格式）

从XYZ格式的服务地址中可以发现，不同服务的地址除了T参数，其余都一样，这里总结了T参数的含义：

T参数	说明
img_w	卫星影像
cia_w	卫星影像注记
vec_w	矢量图
cva_w	矢量图注记
ter_w	地形图
cta_w	地形图注记

2、高德地图

高德地图的坐标与天地图有些偏差，为自定义坐标系（天地图为标准的国家2000坐标系），具体使用过程中需要注意。

高德地图地图主要为：卫星影像，卫星影像注记，深色风格的矢量图带注记，浅色风格的矢量图带注记

提示：

参数s为轮询地址，CesiumEarth中添加图层时可在前缀输入框中填写webst01,webst02,webst03,webst04。
地址中出现的x、y、z为系统默认参数，连同{}，直接复制到CesiumEarth即可。

3、ArcGIS地图

ArcGIS Online提供了多种风格的地图样式，支持XYZ/WMTS/MapServer格式的服务，其中MapServer格式最为简单，无需申请token，直接调用即可免费使用。

ArcGIS是一款全球著名的地理信息专业工具，因此其提供了非常多的免费在线资源，本文只列举几种常用的地图，更多地图资源可查看目录地址：Folder: /

由于ArcGIS提供的是全球资源，因此其注记大多以英文为主。采用了CGCS2000坐标系，墨卡托投影，与天地图可完美匹配，因此具体场景可综合选择不同的地图进行叠加。

二：如何添加及展示地图

在CesiumEarth中支持多种类型的地图加载，使用也非常方便，无需开发知识，本文以天地图的添加为例，具体详情可查阅CesiumEarth帮助文档：添加图层

1、通过添加图层查看

此处以添加天地图卫星影像为例

访问CesiumEarth首页：http://www.cesiumearth.com ，进入三维地球；如果首次使用，可先新建目录，或直接点击添加图层

初始化图层

在图层管理模块中可点击添加图层按钮进行添加，选中二维切片数据选项

图层管理

在窗口中输入相关参数，点击确认即可

名称：图层名称（可随意输入）
格式：选择自定义格式（XYZ格式）
Url：复制天地图卫星影像的地址
注记图：选中后会显示在顶层，一般用于显示注记图层
前缀：输入t0,t1,t2,t3,t4,t5,t6,t7

Locale Dropdown

2：通过复制图层配置查看
