Enabling High resolution Satellite Imagery
You can overlay high-resolution satellite images on the land, sea, or both
portions of the Navigation chart when using a preprogrammed BlueChart g2
Vision SD card.
To enable satellite imagery:
1. While viewing the Navigation chart, press MENU.
2. Select Chart Setup > Photos.
3. Select one of the following:
• Off—standard chart information is shown on the map.
• Land Only—standard chart information is shown on water with photos
overlaying the land.
• On—photos overlay both the water and the land at a specified opacity.
The higher you set the percentage, the more the satellite photos will
cover both land and water.
NOTE: When enabled, the high-resolution satellite images are only present
at lower zoom levels. If you cannot see the high-resolution images in your
BlueChart g2 Vision region, either zoom in further using the Range (+) key, or
set the detail level higher ( page 12 ).
