Animate a series of images with an image overlay.

Image of animate images with image overlay

Use case

An image overlay is useful for displaying fast and dynamic images; for example, rendering real-time sensor data captured from a drone. Each frame from the drone becomes a static image which is updated on the fly as the data is made available.

How to use the sample

The application loads a map of the Southwestern United States. Click the "Start/Stop" button to start or stop the radar animation. Use the drop down menu to select how quickly the animation plays. Move the slider to change the opacity of the image overlay.

How it works

  1. Create an ImageOverlay and add it to the SceneView.
  2. Set up a timeline with an interval period.
  3. For every image, create a new ImageFrame and add it to the image overlay at every timer interval.

Relevant API

  • ImageFrame
  • ImageOverlay
  • SceneView

About the data

These radar images were captured by the US National Weather Service (NWS). They highlight the Pacific Southwest sector which is made up of part the western United States and Mexico. For more information visit the National Weather Service website.

Additional information

The supported image formats are GeoTIFF, TIFF, JPEG, and PNG. ImageOverlay does not support the rich processing and rendering capabilities of a RasterLayer. Use Raster and RasterLayer for static image rendering, analysis, and persistence.
