There are numerous options available for customizing your map drawing in Aqua Map, ranging from adding additional layers like Satellite imagery to adjusting depth coloring and customizing icons and text size.

Additional layers

This is the list of the additional data you can add to the basic nautical charts from the main Settings page:

Land data: Enable the display of complete cartography for the land part, including streets, highways, buildings, forests, and more.

Map colouring

In order to change the coloring of your map you have 3 options in the main Settings menu:

Map Appearance: Here, you can select between the Day or Night map drawing style. The "Auto" setting automatically switches between Day or Night style based on the device appearance (Light or Dark) setting. Note: Night mode is intended for use in low luminosity conditions; under direct sunlight or bright conditions, the contrast may be too low.
Depth Coloring: Here, you can choose the shading style for depth areas. "Standard" draws depth areas as in paper charts, starting from blue for the shallowest depth and fading to white for areas deeper than 20m. "Natural", on the other hand, attempts to replicate natural sea colors, starting from white for shallow depths and darkening to deep blue for areas deeper than 3500m. Note: This feature is not compatible with areas using Raster charts.
Safety Depth: Here, you can set your safety depth. This value determines the limit of blue-shaded depth areas. Depth areas deeper than the "Safety Depth" will be shaded white, while areas shallower than the "Safety Depth" will remain blue-shaded as before. Note: This feature is not compatible with areas using Raster charts.

Map visibility

There is a dedicated page to select the size for most of the icons and texts present on the map and you can reach this page from the main Settings menu.

To enhance clarity, the options have been organized into categories, considering the various types of icons and texts

At the bottom of the page, you'll find a "Restore Defaults" button to reset all icon and text sizes to their original settings.

Map data

The initial group comprises all elements constituting the base cartography.

Map icons size: Adjusts the size of most icons included in the basic cartography. Changes in size will be proportional, maintaining the relative ratios between different icons (smaller icons will remain smaller). NOTE: Some icons related to land data will not change in size (always kept small to prevent clutter).
Map texts size: Adjusts the size of most text elements included in the basic cartography. Changes in size will be proportional, maintaining the relative ratios between different texts. NOTE: Some texts related to land data will not change in size (always kept small to prevent clutter).
Use patterns for map areas: Allows filling certain areas (e.g., Restricted areas, Anchor areas, etc.) with icons representing the area itself. This enhances map clarity but may increase clutter. Use this option to decide whether to display these icons.

User data

The next group includes all the elements that belong to the user (routes, tracks and markers).

Marker icon size: Select your preferred size of the marker icon
Show marker names on map: Enable the drawing on the map of the marker's name (just below the corresponding icon).
