High-resolution Relief Shading
We’ve extended our high-resolution relief shading feature to provide superior coverage for premium BlueChart g3 Vision charts and LakeVü g3 Ultra maps. Now with 100% coverage for the coastal continental U.S. and increased inland acreage, high-resolution relief shading combines color and shadow to give you an easy-to-interpret, clearer view of bottom structure. This makes it easy to find fish-holding structure, artificial reefs, underwater shelves and more.
High-resolution Satellite Imagery
High-resolution satellite imagery is available on both BlueChart g3 Vision charts and LakeVü g3 Ultra maps. Overlaid onto navigational charts, it provides a realistic view of your surroundings and helps enhance your situational awareness.
