Kubla Ports User Manual
To load a new overlay from a file, click on the Add From File button. Alternatively, you can use the drop-down menu on the assets panel to add overlays to other assets. You will be prompted to select the file which you want to load. If you choose a pdf file with several pages you will also be prompted to choose which page to load.
Once you have chosen the file the overlay will normally be displayed on the screen in an arbitrary position. You will then have to edit the scale and position of the overlay to adjust it to its real-world position. However, if it is a geo-referenced image format it will be automatically displayed in its defined location.
To edit the overlay you have loaded, click on the Edit button on the overlay's properties panel. For the option available after clicking on this button see Editing Overlays.
