Past imagery tool


The Queensland Government has a large collection of imagery on offer for use within the Queensland Globe. The imagery, captured by using satellites, planes and drones, can be sourced using the Past Imagery tool.

Use the Past imagery tool to source recent, historical aerial and satellite imagery, whilst in 2D or 3D view mode.

Finding imagery capture date


The best way to find out the date of the imagery that you are trying to identify is to use the Past imagery, located down near the lower right corner of the screen. Navigate to your selected area then open the Past Imagery Tool.

Once activated, you can search through all available imagery within the current map extent and discover capture dates for the most recent Imagery available, as well as historical aerial photography.

Adding the imagery project as a layer ensures you are seeing that project’s imagery and you can be sure of the capture date from the associated project attributes.

Using the past imagery tool


The Past imagery tool is located in the lower right corner of the screen, navigate to your selected area then open the past imagery tool.

The Past imagery tool is scale dependant, zoom in to a scale of at least than 1:50,000 to use it, when the button is greyed out it is unavailable.

  1. Zoom in to the point where the Past Imagery tool icon is highlighted, then click on the icon.
  2. Past Imagery Tool activate
  3. The timeline displayed along the bottom of the screen shows the year of imagery capture with the number below showing how many images were captured. Click on the arrows pointing left/right to explore earlier/later years.
  4. Past Imagery Timeline
  5. Click on a year to select it, the timeline will display prominently the months when the imagery was captured. Use the arrows pointing left/right to explore adjacent earlier/later years.
  6. Past Imagery Month selection
  7. The count of imagery results will be shown per year and then month. When no imagery projects are listed for that month, the month is greyed out and will not allow for selection.
  8. Select the month to display a thumbnail of the image, listed by project. Further information, such as the title of the project, precise date of capture (start and end) and scale will be displayed.
  9. Past Imagery Month selection
  10. You can use the Previous project/Next project options down along the bottom right to toggle through the search results to find the imagery that best suits.
  11. Selecting the Back To (Year) button at top left will return to the timeline to view other years.
  12. Past Imagery selection
  13. Click View gallery to display the thumbnails of the available imagery that falls within the current map extent for the date selected.
  14. With the gallery open, the start of capture date is displayed on the image thumbnails.
  15. View the past image extent
  16. You can select to view images within the gallery by large images or small images.
  17. View image options
  18. Click Close gallery to close the gallery.
  19. A warning message is displayed on the screen if the map extent has been adjusted. The message can be manually dismissed or auto dismissed after 15 secs.
  20. Warning past imagery
  21. Click the orange Refresh past imagery button if this occurs. The imagery available through the Past imagery tool will correctly reflect the adjusted map extent once this has been selected.
  22. Refresh Past Imagery

View past imagery


The Past Imagery tool offers access to a large catalogue of aerial imagery projects and historical imagery frames that can be incorporated into your Queensland Globe map.

Many images align with the map coordinate system used by Globe, which means that we can use the imagery as a base map and overlay it with other layers of information.

There are two types of images available.

  • Rectified images - Typically more recent imagery that have been stitched together to form a mosaic. These can be added as layers to your map directly from the Past imagery tool. These are not available for download.
  • Unrectified frames - The footprint of each of these historical imagery frames can be added as a place, allowing you to retain the attributes for that image. The image and associated world file can be downloaded from QImagery. The Preview image option displays a larger preview of the image selected, and a link to QImagery is available below this preview. If packaged into a .ZIP these can be re-imported as a layer and the Queensland Globe will use the world file to place the geolocated historical imagery frame.

Selection of a rectified image(s) and an unrectified image(s) have the following icon options.

Icon options Description Rectified Image(s) Unrectified Image(s)
Preview on map button Preview on map - This allow you to view the rectified imagery or highlight the footprint of an unrectified image on map, without adding it as a layer or place.
Add as layer button Add as layer - This adds imagery mosaic as a layer to the layers list.
visible-selected-invisible-at-scale Add as a place - This adds imagery footprint to the places list.
make-this-the-only-visible-layer Preview image - Displays QImagery preview and includes a link to the QImagery application.

Swipe Tool


As you can see past imagery tool is a powerful way to research historical imagery and view change over time. You can use the Swipe tool for comparison of both imagery and data layers within two view modes (Horizontal and Vertical).

Swipe tool is available in the 2D mode only and can be used at any scale. It is not available on mobile phone and cannot be printed through the Print function.

The Swipe tool is located in the bottom right-hand corner above the Past imagery tool, click the tool icon to activate it.

Swipe tool

To compare specific layers or image, use the Layers panel to add or make visible the layers that are going to be used in the swipe tool.

Please note to try to keep the swipe tool efficiently try to limit the number of layers that are active.

Once you open the swipe tool, a menu on the bottom of the screen displays left view and right view.

Swipe tool views

Both views are based on the layers currently active on the map in the layers list. Deselecting layers from one side will hide those layers from that view.

You can drag the slider up and down or left and right to view and compare the selected layers.
