3.10.2.5.3 Characteristics of Spatiotemporal Map Layers

This section describes the distinct characteristics of the spatiotemporal map layers when visualizing a spatiotemporal dataset.

  • The trails map layer is considered the secondary layer to the main layer. If you delete the main layer from the map, then the trails map layer is automatically deleted as well.
  • The main layer which shares the same name as the dataset is always a Point-type layer, that you can visualize using either as circle or using symbols or icons. When you use symbols, Spatial Studio will also automatically rotate the symbol based on the direction your object is moving.

    Also note, the current release of Spatial Studio supports only those symbols that naturally point North (or point up) or those that do not represent an inherent direction or angle, such as any rounded symbols.

  • The main layer will keep its animation even when you toggle the secondary layer invisible. However, if you toggle the main layer invisible, the trail layer will remain static as no new data is fetched from the backend.
  • You cannot switch the main layer to Heatmap or Cluster type.
  • You cannot use sticky Tooltip or popup as they cannot stick to the moving object when it moves to new locations.
  • Spatial Studio drives the animation of moving objects and their trails by constantly refreshing the main layer’s data from the backend. This implies that the base table is queried and the last N seconds of data is fetched by filtering the records based on the TIMESTAMP column.
  • If you are working in a multi-user or multi-visualization environment or both, you must take care to avoid overloading the database with many animating layer's data refresh queries. For instance, ensure a layer is not refreshing its data too frequently, or fetching too many seconds of data on each refresh, or both.
