Using the Viewpoint tool in Image Server Viewer

The Viewpoint tool functionality enables you to change the order of multiple overlapping images in an image service to view the same location from different angles or viewpoints. This is a useful feature when you are working with large-scale imagery in urban built-up areas where large buildings can cause blind spots on the ground, since this functionality can enable you to see buildings from various angles. By using the viewpoint functionality, you can shift the obstructing entity in the image and see the terrain entities. You can also see all sides of buildings, which can be useful for a range of applications, such as civil defense.

The viewpoint functionality can be used in image services with overlapping images where the Viewpoint mosaic method has been enabled by the administrator of the image service.

Steps:

1. Open an image service.
2. Click File and click Properties.
3. Click the Service Properties tab.
4. Click the Mosaic Method drop-down arrow and click Closest to Viewpoint.
5. Click OK to close the Service Properties dialog box.
6. Click the Zoom In button and zoom in to a portion of the image service.
7. Click File on the Main menu and click Viewpoint to display the Viewpoint window.

8. Click the centerpoint button in the Viewpoint window.

   The autocalculated centerpoint x- and y-coordinates of the area of interest are displayed on the dialog box. You can type your own values to replace the autocalculated values to change the centerpoint.

9. Click any of the Viewpoint arrow buttons to change the coordinates in the specified direction.
10. Click OK.

    The viewpoint of the image service changes from the selected direction.

    Note:

    If you do not notice a change in the viewpoint, the raster for the particular view is not available.
