Navionics, Inc., a Garmin company, announced it has developed SonarChart Shading for its Platinum+ and HotMaps Platinum cartography products for coastal and inland fishing and boating.

Embedded within the satellite overlay content layer, SonarChart Shading provides a detailed rendering of the seafloor. Created from the high-definition, 1-inch contour data within SonarChart, varying shades of blue reveal changes in depth, highlighting channels, drop-offs, and other features that help boaters gain a situational awareness and offers inland and coastal anglers clear, visual cues to identify fish-holding structure.

“SonarChart Shading is a natural progression of SonarChart,” said Marcello Albanese, Navionics director of sales and business development, in a statement. “It puts to use the enormous amount of depth data we’ve amassed from proprietary surveys and crowd-sourced contributions in the form of a completely new visual display for our customers.”

SonarChart Shading can be viewed on the same GPS chartplotters that are compatible with HotMaps Platinum and Platinum+ satellite overlay and with the same options, including selectable overlay on land, land and shallows or full overlay. Adjustable transparency allows customers to view the new imagery blended with either the SonarChart bathymetry map or the Nautical Chart.

At closer zoom levels, SonarChart Shading is replaced by the actual satellite imagery over water, allowing boaters to see a bird’s eye perspective of sandbars, marshes and backwater channels.

Platinum+ and more than 2,600 lakes HotMaps Platinum lakes will offer updated and optimized high-resolution satellite imagery. Some lakes may have partial coverage.

SonarChart Shading is expected to be available beginning in mid-spring with HotMaps Platinum for U.S. and Canada.
