FAQ（常见问题解答）¶
Are geotemporal series generally available?¶
Geotemporal series are in the beta phase of development and may not be available on your enrollment. Functionality may change during active development.
When should I use geotemporal series instead of time series to display geospatial data?¶
If you plan to display your geospatial data on a Gaia map, then you should use geotemporal series. Geotemporal series require latitude and longitude coordinates alongside a timestamp and series ID. Use geotemporal series if your tracking data includes an additional measurement value alongside its coordinates, such as speed or altitude. Geotemporal series store latitude, longitude, and a measurement value together in a single series, which can simplify your data model when you need to correlate location with other values. Learn more about integrating geotemporal series with the Ontology.
If you plan to display your geospatial data on a Foundry map, then you should use time series. You can use time series properties to track the movement of entities over time by storing latitude and longitude pairs as separate time series to display on a Foundry map as track objects. Using time series for geospatial entity tracking is appropriate when your data contains latitude and longitude measurements recorded at different timestamps, such as GPS coordinates for ships or vehicles, without an additional measurement value. Learn more about creating time series syncs that back track objects in your Ontology.
Can I implement both geotemporal series and time series simultaneously?¶
If you plan to view your geospatial data on both Foundry and Gaia maps, then you can create a geotemporal series sync that produces a geotemporal reference property and create a time series sync that produces time series properties on your object type. Objects displayed on a Foundry or Gaia map that implement both are read-only, so users may only view the objects on each map as opposed to executing actions on one or multiple. You should avoid implementing both series types unless necessary for your specific use case.

常见问题解答¶
地理时间序列是否已全面可用？¶
地理时间序列（geotemporal series）目前处于测试版开发阶段，您的实例可能暂未开放此功能。在活跃开发期间，相关功能可能会发生变化。
何时应使用地理时间序列而非时间序列来展示地理空间数据？¶
如果您计划在Gaia地图上展示地理空间数据，则应使用地理时间序列。地理时间序列需要同时包含经纬度坐标、时间戳和序列ID。当您的追踪数据在坐标之外还包含额外测量值（如速度或海拔）时，建议使用地理时间序列。该序列可将纬度、经度和测量值统一存储于单一序列中，从而在需要关联位置与其他数值时简化数据模型。了解如何将地理时间序列与本体集成。
如果您计划在Foundry地图上展示地理空间数据，则应使用时间序列。您可以通过时间序列属性将经纬度对存储为独立的时间序列，以追踪实体随时间移动的轨迹，并在Foundry地图上以轨迹对象形式展示。当您的数据包含不同时间戳记录的经纬度测量值（如船舶或车辆的GPS坐标）且不包含额外测量值时，使用时间序列进行地理空间实体追踪更为合适。了解如何创建支持本体中轨迹对象的时间序列同步。
能否同时实现地理时间序列和时间序列？¶
如果您计划在Foundry和Gaia两种地图上查看地理空间数据，则可以在对象类型上创建生成地理时间引用属性的地理时间序列同步，同时创建生成时间序列属性的时间序列同步。同时实现两种序列的对象在Foundry或Gaia地图上显示为只读状态，因此用户仅能在各地图上查看对象，而无法对单个或多个对象执行操作。除非特定用例确有需要，否则应避免同时使用两种序列类型。
