Chart Object Search PlugIn for OpenCPN 4.x.x

Allows search of named objects on S-57 and CM93 vector charts.

Note: After the installation, the plug-in does not know anything about your charts, you must view a chart at least once to populate the plug-in's database with it's content. This one time operation makes OpenCPN slower, during subsequent views of the same chart the speed of the application is unaffected. Once the database is populated, the charts are no longer needed, so if you prefer to use raster charts, you can populate the database from the ENC chartset and then switch back to RNC charts and the search capabilities will still be available.
