S-57 Java Suite

This suite of applications uses a common class library that provide the means to convert data between OSM and S-57 formats.

Structure

In this illustration, the top line (OSM input, Editor, OSM output) represents JOSM together with the "seachartedit" plugin.

The S57 translation blocks convert OSM data or S57 ENC data to/from an internal binary model that is compatible with both OSM structures and the S57 chain-node model used by ENC.

The binary data model provides the inputs to various renderers, host displays & file outputs.

The renderer will provide the core engine for applications besides JOSM, principally our map tile generator, but also could be used in other applications, such as chart plotters.

The renderer's output is sent to the host display (an imagery layer, "seachart", in JOSM or a chart plotter screen). The rendering applications can output both PNG and SVG tiles.

Component Applications

SeaChart

This is the primary application of the suite. It provides an imagery layer plugin for JOSM. It renders a complete chart as would be generated by the base layer and seamark layers of the renderer.

Jrender

This is the seamark layer renderer. It generates PNG tiles for the online map.

Jicons

This renders PNG or SVG icons of point objects for use in third-party charting applications. Its input is an OSM-style XML file using the seamark tagging scheme, plus additional tags to specify the scale, alignment and format of the icons.

Jbasemap

This generates SVG images of natural and cultural map features, rendered in the INT-1 style. Its input is a bounded OSM file.

Jplotter

A real-time chart plotter.
