i-Boating app now supports custom depth shading to highlight shallow areas. I've included a specific example at the end illustrating how to use and before/after screenshots.
1. Without depth shading
2. With depth shading
3. How I figured out what value to choose for shading?
Before depth shading
For e.g. this is what the default map looks for New Jersey inter coastal waterway. There are two depth areas here (one below 2.95 ft and the other above it). When navigating you would want to highlight the shallow area with a different color.
With depth shading
Here is how to use depth shading:
Tap menu/overflow button and select "Settings"
Scroll down and check the box that says "Enable Custom Depth Shading"
Change shallow depth to 0 ft and safety depth to 2.9f ft
Here is a screenshot with custom depth shading.
How to figure out what value to use?
You can use object query to find out depth range of an area. Simply long touch any where int the area and select "Object Query".
Viewing marine charts and fishing maps over satellite imagery and regular street maps was requested by several i-Boating customers. We are pleased to announce that the feature is now live on Android devices. (iOS version will become available upon Apple approval).
We have provided multiple different sources (currently 10 sources) of basemaps for i-Boating customers to choose from including street maps, USGS Topos, USGS aerial, satellite imagery and more.
Here is how to change the background maps:
Tap menu/overflow button on top right and select "Settings"
In Settings screen select "Refresh Available Sources" from the dropdown.
Select one of the several background maps
Tap on Save
I've added a few screenshots with this in action from my Android phone (for Lake Constance/Bodensee and San Francisco Bay).
We have recently added support for water level offset in i-Boating. This lets i-Boating users adjust the depth shown on the maps. If you have had less rain in your area (e.g California drought), you may want to decrease the depth shown on the map by specifying a negative value for depth offset. This would change all depth values shown on the map.
Tap on menu/overflow button (lower right on iPhone, top right on Android).
Type in the depth offset you wish to choose.
Tap to Save
I've also attached a few screenshots below showing the settings screen on both iOS and Android.
We are pleased to announce that we have added support for coverage of Persian/Arabian Gulf, Red Sea & Gulf of Eden. The folio covering this region is available in i-Boating for both iOS and Android devices.
The folio includes coverage of the following regions:
