How do I Add a Background Image?
Background images are used to help layout airports. These images are not photo scenery and ADE does not compile them into the simulator. There are a lot of different types of background image that can be used. These can be images taken from something like Google Earth or perhaps a published airport layout diagram. The important thing is that these need to be in a recognized image format for ADE to use. Also it is a good idea to keep the size of images as small as possible, If you are working on a large airport then consider using several small images rather than a large one
- Click this button to select the image file
- Choose your image file
- Click Opem
- The file name will be shown in this box
- If you have an image where you know the top left and bottom right coordinates then check here
- and the coordinate boxes will be open for you to enter the details
- Click Save to insert the image into the ADE Display
NOTE If ADE has difficulties with the size or format of the image file it will issue a warning.and won't load the file. In this case check the format of the file and make sure it is a normal image file such as a jpg, png and so on. Also look at the size. If it covers a big area then consider cropping it to a smaller area.
Size and align the image
If you have used the coordinates method to place the image then it should be accurately aligned with the airport in ADE. In many cases you might not have the actual coordinates of the image. For this case ADE provides a method of sizing and placing the image with respect to the airport. This is done by identifying an object in the ADE display where the details are accurately know. Runways are the best for this because they are often the largest features and there dimensions and heading are well known. We will use this method to set up our image.
- First drag the image so that the ADE runway is roughly aligned with the runway in the image
- Then make sure the image is selected. Selected images have a red diagonal X on them
- Now right click and select Position Image
Position the image with the Position Image Tool
This looks a bit complicated but is divided into two distinct functions:
- Controls to size and position the image
- Controls to pan or zoom the display
- Scale will make the image larger or smaller while maintaining the aspect ratio
- Use Width if you just want to change the width of the image without affecting height
- This changes height without affecting width
- Sometimes images may not be accurately aligned to North and you might need to rotate the image a bit
- Move the whole image with respect to the ADE airport
- Pan the display - this does not affect the relationship between image and airport
- Zoom the display in or out
It can take a little while and be a bit fiddly but the ADE runway is now aligned with the image.
Lock the image now so that you don't accidentally move it!
and save the project before doing anything else.
