你好@匿名用户我需要离线街道和卫星高程地图与路由约十几个国家。我有几个问题:1。我知道我需要ArcGIS Publisher。但是我需要什么版本的ArcGIS Pro呢?专业基础，专业标准，还是专业高级?只有当你想在我们的现场应用程序(如现场地图)中创建一个匿名使用的离线地图包时，才需要ArcGIS Pro的Publisher扩展。地图和场景包(mmpk / mspk)将多个数据源和层定义结合在一个现成的地图或场景定义中，ArcGIS地图游戏引擎sdk还不能读取它们。相反，游戏引擎sdk可以读取场景层包(slpk)和Tile包(TPKs/TPKXs)，每个包都为单个层提供数据，您可以使用这些数据构建ArcGIS地图。这些slpk, tpk和tpkx可以在任何版本的ArcGIS Pro中创建(没有Publisher扩展)。您可以使用ArcGIS Pro创建3D对象数据或集成网格数据的场景层包，或基线地图数据或lerc编码的高程数据的Tile包。 2. After I create the offline maps that are accessible through Unity, do individual users need ArcGIS subscriptions or are those offline maps covered by my subscription? They do not, no. Just distribute and use the SLPK/TPK/TPKX files and consume them in your app. As always, make sure you're honoring the data usage rights for the data you're including in your offline packages. 3. Is there any documentation or examples of how I access these offline maps from within Unity? Yes... https://developers.arcgis.com/unity/maps/tutorials/display-a-map-api/ Just reference the locally stored file instead of the service when creating each Layer. See these links for more info: https://developers.arcgis.com/unreal-engine/layers/#set-a-basemap https://developers.arcgis.com/unreal-engine/maps/elevation/#set-elevation 4. Does it matter whether maps are online or offline for routing? At this time, routing in the ArcGIS Maps SDKs for Game Engines requires a connection to a routing service. However, the map layers themselves on which you overlay the route results can be any combination of online or offline layers. The two things (routing and layers) are distinct. 5. Do individual users need ArcGIS subscriptions to do routing, or can I use my API key? They do not need ArcGIS Subscriptions, no. You can use your API Key to deliver solutions that do routing (you get 20,000 routes for free per month). Depending on the nature of the app, and the target users, some developers choose to require/let their users use their ArcGIS Subscription, and you can certainly do that, but it's not a consumer-oriented approach. If your target users are not already ArcGIS subscribers, then an API Key is the appropriate approach. Hope that helps!
