ArcGIS Earth 桌面版新功能（2026年1月）

You asked, we answered. The ArcGIS Earth product team is excited to announce the release of the Historical Imagery Explorer, a new tool that lets you browse the Wayback Imagery archive using an interactive timeline widget. The challenge of manually browsing ArcGIS Online for Wayback Imagery tile layers, only to discover there’s no recent update in your area, is a thing of the past. 你提问，我们来解答。ArcGIS Earth 产品团队很高兴地宣布推出历史影像浏览器，这是一款新工具，可让你通过交互式时间轴组件浏览 Wayback 影像档案。过去那种需要手动在 ArcGIS Online 上浏览 Wayback 影像瓦片图层，结果却发现你所在地区没有最新更新的麻烦，如今已成为历史。

What is Wayback Imagery? 什么是Wayback影像？
Wayback imagery is a digital archive of the World Imagery basemap that enables you to access versions of World Imagery captured over the past 10+ years.Wayback影像库是全球影像底图的数字档案，它能让你访问过去10多年间拍摄的全球影像版本。

 

ArcGIS Earth Historical Imagery Explorer ArcGIS Earth 历史影像浏览器

ArcGIS Earth’s Historical Imagery Explorer leverages core functionalities to identify versions of the Wayback archive that contain updates based on your view extent and zoom level. As you navigate the globe, the interactive timeline widget dynamically updates, displaying only dates where relevant and updated imagery is available.ArcGIS Earth的历史影像浏览器利用核心功能，基于您的视图范围和缩放级别，识别包含更新内容的Wayback档案版本。当您在地球仪上导航时，交互式时间轴控件会动态更新，仅显示有相关且更新的影像可用的日期。 

How Does it Work? 它是如何工作的？ 

While ArcGIS Earth is a .NET based application, it’s Historical Imagery Explorer draws heavy inspiration from the logic found in the wayback-core JavaScript library. The tool accesses the Wayback catalog through the ArcGIS Online Wayback Imagery group. ArcGIS Earth retrieves WMTS (Web Map Tile Service) data, including release dates, and dynamically displays imagery based on the specific timeframe you select. 虽然ArcGIS Earth是一款基于.NET的应用程序，但其历史影像浏览器的设计深受wayback-core JavaScript库中逻辑的启发。该工具通过ArcGIS Online的Wayback影像群组访问Wayback目录。ArcGIS Earth会检索WMTS（网络地图瓦片服务）数据（包括发布日期），并根据您选择的特定时间段动态显示影像。 

Smart Filtering 智能过滤 

The Wayback archive hosts a large number of releases, but not all of them include updates for the specific area you are viewing. To keep your experience smooth and relevant, the Explorer uses the Tile Map API to determine which imagery versions have tile data updates available for your current location.Wayback 档案库中存有大量版本，但并非所有版本都包含您正在查看的特定区域的更新。为了让您获得流畅且相关的体验，浏览器会使用瓦片地图 API 来确定哪些影像版本拥有当前位置的瓦片数据更新。 

Here are a few things to know about how smart filtering behaves:以下是关于智能过滤机制的几点说明： 

• Contextual Relevance: Imagery versions where no changes occurred are filtered out so you only see changes that matter to your current view. 上下文相关性：未发生变化的图像版本会被过滤掉，因此您只会看到与当前视图相关的变化。

 

• Altitude Limitation: To maintain performance, dynamic filtering begins when the camera is below 30km altitude.  高度限制：为保持性能，当相机处于30千米以下高度时，动态滤波启动。

 

• View Extent Accuracy: The tile at the center of your view extent is used as the representative sample for filtering which versions contain change.  视图范围精度：视图范围中心的瓦片用作代表性样本，用于筛选包含变更的版本。

Currently, the Historical Imagery Explorer focuses on the release dates of the World Imagery Basemap. However, the Wayback archive is rich with metadata. Each version of a tile can technically be queried to reveal its acquisition date, imagery provider, and spatial resolution. While ArcGIS Earth doesn’t query this metadata for every single image to keep things fast, we are looking into possible ways to expose this level of detail to you. 目前，历史影像浏览器主要关注世界影像底图的发布日期。然而，Wayback档案包含丰富的元数据。从技术上讲，每个瓦片版本都可以通过查询来显示其获取日期、影像提供商和空间分辨率。虽然ArcGIS Earth为了保证速度，不会对每一张图像都查询这些元数据，但我们正在研究可能的方法，以便向您展示这一详细程度的信息。 

The Historical Imagery Explorer is available to the public and does not require a specific user type. 历史影像浏览器向公众开放，无需特定用户类型。

How to access the Historical Imagery Explorer 如何访问历史影像浏览器

You will find the  Historical Imagery Explorer under  3D Effects in the main toolbar. The Historical Imagery Explorer is only supported when the spatial reference is set to Web Mercator. If the current scene is set to WGS84 the Historical Imagery Explorer will be unavailable. 您可以在主工具栏的“3D效果”下找到“历史影像浏览器”。只有当空间参考设置为Web Mercator时，“历史影像浏览器”才受支持。如果当前场景设置为WGS84，“历史影像浏览器”将无法使用。
