4.1.2 Viewing a Pleiades image in Monteverdi

You can open the Pleiades image in the viewer, either by using the contextual menu or by opening the Viewer Module through the menu bar.

You can notice that the viewer opens quickly without showing the traditional progress bar. This is because Monteverdi already loaded the quick-look upon opening, and we do not need to re-compute it each time the image is opened in the Viewer Module.

Figure 4.3, page 174 shows a Pleiades image displayed in the Viewer Module. One can notice that the navigation experience is rather smooth. If you navigate using arrows keys, you will notice that latency can occur now and then: this is due to the viewport switching to a new Jpeg2000 tile to decode. On can also observe that the latitude and longitude of the pixel under the mouse pointer is displayed, which means that the sensor modelling is handled (if you have an internet connection, you may even see the actual name of the place under mouse pointer). Last, as said in the foreword of this section, Pleiades image can be quite large, so it might be convenient to switch the viewer style from Packed to Splitted, in which case you will be able to maximize the Scroll Window for better localisation of the viewed area. To do so, one can go to the Setup tab of the Viewer Control Window.
