Learn the basics of Oriented Imagery through 2D and 3D apps

How does the 2D Oriented Imagery viewer work?

Using a web app built with an 2D Oriented Imagery widget is simple:

  • Click on oriented imagery icon to open the Oriented Imagery widget.

  • Select an Oriented Imagery Catalog (OIC) by clicking on + in the Oriented Imagery window.

  • Sign-in to ArcGIS Online (Optional).
  • Select Sample OICs option in the From drop-down list.
  • Select EsriCampus20180701B in the OIC drop-down list. Click on “Add”.
  • Check the Coverage map box to see the coverage area of the images.
  • Click a location on the map within the coverage area.
  • An imagery viewer will show you any available oriented images depicting that point.
  • As you pan and zoom in the image, see the camera’s field of view dynamically illustrated on the map.
  • Check the Image exposure points box to view exposure points that also contains the location you selected.
  • Check the Additional coverage box to view the coverage area of the exposure points that contains the selected location.
  • Uncheck the Additional coverage and Image exposure points boxes.

Image Enhancement tool in Oriented Imagery

This tool has two sliders that allow the user to interactively adjust the contrast and brightness of the image.

  • Click on the image enhancement tool in the Oriented Imagery Viewer.

  • Move the brightness slider to 5 and the contrast slider to midway between 0 and 5.
  • Reset the sliders by clicking on the reset button.

Navigation tool in Oriented Imagery

Oriented Imagery viewer has a navigation tool for the visual representation of all the images that contains the selected location, which is seen as a red X on the map and in the Imagery Viewer. The tool is a compass depicting the camera locations for all relevant images, with the selected location in the center. The tool is divided into four quadrants (north, south, east, and west); each quadrant is divided into three segments, which the show relative distance of the camera from the selected point. 

  • Click on the navigation tool icon in the Oriented Imagery viewer.

  • The image shown in the imagery viewer is a pink dot on the compass, and the viewshed of the camera is shown in green. Any additional images depicting the selected location are blue dots on the compass.
  • Click on any blue dot to view a different image.
  • Now, click on any ring segment that contains blue dots. The navigation tool will select the best image from all the image exposure points that lie within that ring segment.

How does the 3D Oriented Imagery viewer work?

Using a web app built with 3D Oriented Imagery widget is simple:

  • Click on oriented imagery icon to open the Oriented Imagery widget.

  • Select a location in the web scene within the Mesh area.
  • An imagery viewer will show you any available oriented images depicting the point.
  • As you pan and zoom in the imagery viewer, the camera's frustum is dynamically updated in the scene.
  • Press Alt key and click on the Mesh. The green diamond shows the location of the point in the image.
  • Close the Oriented Imagery Viewer window.

3D Image viewer mode

3D Oriented Imagery widget has two image viewer modes - 2D and 3D. In 2D mode, image is displayed in a separate window while in 3D mode, image is displayed in the web scene.

  • Click on 3D option for the Image viewer mode.

  • The widget will display the image in the web scene. Once the image is loaded, pan and zoom in the web scene.
  • Click on Layer List icon.

  • Toggle Chateau190727 - Mesh layer to see the overlap with the image.
  • Click on Oriented Imagery icon.
  • Click on Click here to remove image from scene.
  • Click on 2D option for the Image viewer mode.

Digitizing features in Oriented Imagery

  • Select a location in the web scene within the Mesh area.
  • Click on the Add button in the Vector layer(s) section. This will add the Windows vector layer to the imagery viewer.
  • Minimize the Oriented Imagery widget window by clicking on minimize icon (-).

  • Click on overlay icon in the Oriented Imagery viewer window.

  • Check the Windows box to enable the editing tools.
  • Click on + to add features.
  • Before digitizing windows in the image, we need to set the distance of the window from the camera. To do this, first enable the set distance tool by clicking on Distance icon.

  • Click on any windows within the frustum area in the Mesh to set the distance.
  • Draw a polygon around the same window in the image. Double click to end the drawing.
  • A polygon feature will be added both in the image and in the web scene.
  • Click on x button in the Overlays to delete the feature.
  • Click on the blue polygon in the image to delete the feature that we just recorded.
