嵌入式电子海图仪中海图文件的数据结构

Data Structure of Files in Embedded Electronic Chart Apparatus

为了提高嵌入式电子海图仪的海图显示速度,增强数据的有效性及减小存储容量,采用自定义的非标准化数字矢量海图,数据格式按点、线、面分类,与嵌入式处理器显示处理方案自成一体,不但能提高海图仪显示海图时的处理速度,简化硬件设计,还能增强产品的保密与安全性。

For improving chart display speed of embedded electronic chart apparatus, enhancing effectiveness of data and reducing storage capacity, a specially designed nonstandard digital vector chart is adopted, of which the data formats are classified into dot, line and surface, and integrated with embedded processor display management scheme. This way not only improves sea chart apparatus processing speed when displaying chart and simplify hardware design, but also strengthens security and secrecy of products.
