Aerial photo overlay
You can overlay an aerial photo on to the chart display, helping you to interpret your environment and its features.
If you are using a suitable chart card, you can overlay an aerial photo on to the chart display. This covers the navigable waters up to three miles inside the coastline.
Beyond these limits, the land will appear green, and the resolution is dependent on the region covered by the chart card you are using.
Using the options in the Cartography Setup Menu, you can specify whether the aerial photo overlay is displayed for land areas only, or for land and sea areas.
You can also adjust the opacity of the aerial photo overlay if required.
