4. Graphic display of flight lines and images#

../_images/NG_fl_graphic_display.png

As soon as an image has been captured it becomes apparent through its color and symbol representation.

During flight and in simulation mode, a blue line flashes briefly under the line deviation indicator above the main display window to show the command for the release of a picture has been sent to the camera. As soon as the picture has been taken and successfully saved, a green line briefly flashes under the line deviator. Some cameras operate so fast that only the green line will be visible.

The image symbol will switch from red to green as soon as the image has been taken and saved.

In the example above, all images of lines 1 to 4 have been captured and those of lines 5 to 7 have not yet been captured.

4.1. Colors and symbols for lines and images#

Line

Description

../_images/NG_fl_symbols1.png

All images are colored red: the images have not yet been taken. Therefore, the line is also colored red.

../_images/NG_fl_symbols2.png

All images are colored green: the images have been taken. As all the images on the line have been successfully captured, the entire line is also colored green.

../_images/NG_fl_symbols3.png

The images are cross marked with green color: The images were successfully taken; however, the operator designated them for retake, possibly due to adverse conditions like excessive fog. Under more favorable weather conditions, these images will be retaken. As they are slated for capture on a subsequent date, the corresponding line is highlighted in red.

../_images/NG_fl_symbols4.png

The images have been taken. However, the camera issued warnings (underexposure or other warnings). The images are colored orange, the line is colored red.

../_images/NG_fl_symbols5.png

Some images have been taken, some not. Only part of the line has been flown and therefore the line is colored orange.

../_images/NG_fl_symbols6.png

The images have been taken. However, images no. 3 to 8 are cross marked. This means that these images must be retaken at a later date when the conditions for aerial imaging are better at this location.

../_images/NG_fl_symbols7.png

Navigator / SensorHandler sent the capture command to the camera but the camera did not reply that the image has been taken. Therefore, the images are colored blue. When this occurs, the photographer needs to inspect the system components, e.g. the state of the camera and INSS.

4.2. Filtered display of images#

The following buttons are available to filter information of the displayed images:

../_images/NG_fl_filter1.png

When a line is selected, only the images of this line are displayed.

../_images/NG_fl_filter2.png

When the above button is clicked a second time the images of all lines are displayed.

../_images/NG_fl_filter3.png

The button with the green dot can be used to show or hide all image centers that have already been taken.

../_images/NG_fl_filter4.png

The button with the red dot can be used to show or hide all image centers that have not yet been taken. The images marked as retake are also counted among the images not yet taken.

../_images/NG_fl_filter5.png

The button with the warning icon can be used to show or hide the centers of all images taken whilst a warning message from the camera existed.



Examples of filtered display of image centers:

1. Display of all images:

../_images/NG_fl_example1.png

2. Display of the images which have been taken:

../_images/NG_fl_example2.png

3. Display of the images not yet taken and to be retaken:

../_images/NG_fl_example3.png

4. Display of the images with warnings:

../_images/NG_fl_example4.png

4.3. Resetting the display of flight lines#

4.3.1. Changing the state of partly flown and fully flown lines#

The color representation of the lines and images can be changed in this dialog box:

../_images/NG_fl_reset.png

The graphic below shows a plan with fully flown, partially flown, and not flown lines. Images to be retaken are cross marked.
../_images/NG_fl_reset_plan.png

4.3.2. Changing the status of a single image#

Display changes can be made manually for individual (or all) images of a line.

Example of manual display changes:

../_images/NG_fl_status1.png
In the graphic on the left, the green color indicates that all lines were captured.

After a closer inspection it was found that the landscape was covered in snow on the first 6 images of line 3. These images will have to be retaken at a later date and, therefore, are to be marked.
