Abstract
The invention relates to a method for associating an unstructured navigation book table with an electronic chart. The method is technically characterized by comprising: splitting and numbering unstructured navigation book table PDF files according to a hierarchical structure of chapters; taking the navigation book table name as a database name, establishing a table with the name as a main table, adding chapter numbers, chapter names, chapter contents, positions, latitudes, longitudes and chart fields, realizing an automatic storage function of the chapter numbers, the chapter names and the chapter contents, and manually supplementing other field contents; by using the tree list and the PDF assembly in a combined mode, realizing the restoration display function of the non-structural navigation book table; and realizing associated interaction between the content of the unstructured navigation book table and graphic display by utilizing the position and chapter number attributes. According to the method, accurate positioning and spatial association of navigation book table data are realized by utilizing PDF file splitting, warehousing and bidirectional retrieval, so that the navigation information query and retrieval efficiency is effectively improved, and the informatization capability of navigation is promoted.
