SE ECDIS探索 -- 日志
ECDIS 系统在运行过程中产生的很多数据必须被保存下来，作为后续航行的参考或其它一些决策的依据。这其中包括：航行日志、航迹日志和海图日志。
航行日志： 航行过程中的数据，包括发生的事件，响应的传感器，当前船的经纬度，对地速度，对地航向等。一条航行日志记录包括以下数据：日期时间（UTC时间）、事件、主传感器名称、辅传感器名称、经纬度、对地航向、对地速度、显示的图等。具体内容如下表所示：

航迹日志： 记录了航迹信息，包括当前船的经纬度、对地速度、对地航向、当前显示的图的具体信息等，航迹日志记录的数据直接用于回放。
航迹日志
海图日志： 记录了海图数据相关的历史信息，包括海图安装、自动更新、手动更新和海员标绘。一条记录中包括时间、类型和操作结果。

界面上以表的形式呈现日志内容，并且有选择查看时间段内日志和查看最新24小时内日志的功能。点击“Show”按钮，显示所选时间段内的日志记录，如果时间段内没有日志记录会弹出相应错误提示；点击“Reset”按钮，显示最近24小时的日志记录。
实现方面，使用了轻量级数据库sqlite。
