Contour line Density & Smoothing

The contour line interval adjusts automatically based on the zoom level, but you can also choose a density level manually. We recommend experimenting with the density settings, as areas with diverse terrain and slopes might benefit from different contour line densities. If the contour lines are set to a very high density, they can appear overly sharp and make the display look "noisy." This can result in numerous small, isolated areas that hinder readability. To mitigate this, you can apply an averaging filter to smooth out the contour lines.

Color Gradient Depth Range

The background of the chart features a color gradient transitioning from blue for shallow waters to white for deeper waters. To enhance contrast in either shallow or deep regions, you can modify the deep water threshold between 20 and 300 feet by tapping on the depth value.

Depth Shading

To visualize bathymetric data with a vivid color scale, activate the Depth Shading overlay. This overlay can be applied to any chart type, including Vector, Raster, or BathyVision. The color scale's minimum and maximum values are automatically determined. You can adjust the color palette and the transparency of the depth shading in the plotter settings.

Terrain Shading opacity

When BathyVision is activated or the Depth Shading overlay is turned on, the screen automatically applies a Terrain Shading opacity. By default, this opacity is set to 50%, but it can be modified in the plotter settings under "Terrain Shading Opacity" at the page's bottom. In certain regions, increasing the opacity may dramatically enhance the visibility of the seabed.
