摘要

地理資訊系統的建立需依賴正確且迅速的資料搜集，解析測圖儀數值地形資料檔是其主要來源之一。本研究主要構想是利用CAD軟體故作爲數值儀器與GIS系統間的介面軟體，本研究分兩階段，本文是討論第一階段實驗後的結果。文中首先分析BC-1地形圖檔的檔案結構以及檔案如何重組供CAD軟體使用；其次討論如何在CAD軟體中設計圖例；然後以台南市中山公園爲實驗區測試其可行性；最後討論BC-1應如何配合電腦輔助繪圖需求，預先做好數化數值地形圖的準備工作；並提出第二階段進入GIS系統的構想。

The establishment of geographic information system requires accurate and immediate data collection, digital topographical file from analytic plotter is the main source of data. The essential idea of this research is to use CAD package as the interface software between digital photogrammetric instruments and GIS system. The study has two phases, the paper is to discuss the experimental results of the first phase. This paper first analyzed the data structure of BC-1 topographic data file and reorganized the data file for the use of CAD software. Second, the paper discussed the symbol design of map legend in the CAD software. Then Chung-Shun park in Tainan city was taken as test area for the study of feasibility. In order to conform the requirement of the application of computer-aided cartography, the paper discussed how to do the preparatory work for the digitization of topographic data in the BC-1 environment. The paper finally proposes a strategy of the development of topographical data for DIS in the second phase.
