Locman

Locman (Location Manager) is an Android app designed to help sailors to navigate with all kinds of vessels.

For the background the program uses nautical vector-charts in the S57 standard and those charts are free of charge..

All available charts can be downloaded from the internet and will be translated to the format used by the app.

The charts contain all information for the sailor to navigate safely. They contain the actual buoyage and the most recent soundigs.

Frequently updates appear for the existing charts, small files with, mainly little modificatons in the buoyage.

These updates can, after they've been downloaded, handled by App4sail as well, so all modifications can made visible very easy.

The charts can be presented in different scales.

The user can add waypoints, wich can be shown in several ways.

During the navigation the actual position is continuous displayed on the chart. The chart will be refreshed automatic.

You may evaluate this trial version of Locman during 30 days.
