摘要: 認知超載現象是指當電腦使用者在剛接觸到一堆資料的同時,沒有辦法直接接收到這些資料所要闡述的意義,因此,在資料庫或是資料倉儲資料呈現上,視覺化技術將取代以往文字或是表格描述資料的方式。在本篇論文中將會在漁船資訊傳送系統中導入視覺化的技術,主要的工作有二個方面:首先是電子海圖精密度的提昇,使漁船軌跡可以精確的在電子海圖上顯示;另一方面則是在資料倉儲的線上分析中做圖表等視覺化的呈現,讓資料能在第一時間裡展現出其特性。
Cognitive overload phenomenon means that computer users suffer from how to catch the contents of huge data at first glance. As a result, visualization technology instead of textual or tabular representations has become more and more significant in the applications of database and data warehouse systems. In this thesis, visualization technology is proposed for solving the cognitive overload phenomenon in Vessel Information Propagating System (VIPS) as more data warehouses are added in recently. Essentially it involves two major improvements. One is the refinement of fishing ground maps for reducing the ambiguity of vessel trails when more data displayed on the map. The other is to add more visual features in the On-Line Analytical Processing (OLAP) part of data warehouse. The empirical study shows the feasibility of this visual approach.
