目前，網路地圖格式普遍仍為傳統網格式圖片，網格式地圖在視覺
效果上雖然提供了豐富的色彩呈現，但隨著地圖精緻度的增加檔案容量也隨之相對變大，且網格式地圖缺乏與使用者互動的功能之重大缺點仍是無法解決。向量式網路地圖雖然改良了網格式地圖在互動功能上的缺點，礙於各軟體廠商所開發的向量式地圖產品皆使用了專有的資料格式，因此也無法成為理想的公開網路地圖用的資料格式。近幾年，由W3C 所公開認證的可變式向量圖形SVG（Scalable Vector Graphics），繼承了延伸標記語言XML 開放式資料結構的優點，保有向量式地圖的互動編輯功能，更具備網格式地圖的豐富色彩之展現能力，迅速地成為互動式網路地圖的適當格式。

本研究以台南市地形圖圖例樣式做為圖例設計之參考基準，設計出
相容SVG 幾何圖元及空間資料庫PostgreSQL 的圖例庫。系統開發以相容Java 語言的系統架構為設計基礎，開發出一個具備自適應展圖功能的雛形系統。此雛形系統可透過行動裝置之標準通訊協定傳送使用者的索圖需求，整合OGC WMS 規範的地理伺服器GeoServer 提供系統圖資，生成包含客製化圖例之最終地圖成果，系統並提供圖例樣式設定之互動編修、管理的功能。最後，本研究以三個模擬情境進行雛形系統之完整的功能測試，搭配設定個人化資訊中不同的參數，成功地驗證利用SVG發展具互動功能之自適應展圖服務之可行性。

Raster picture is still the general format of web map service at present.Although raster maps have the ability of representing abundant color on the visual effect, the more fine the map achieves the more volume the file needs
relatively. The great shortcoming such as lacking the interacting capability with user or expansion of the system function still can’t be resolved. Vector
map indeed improves the drawback of interaction capability in raster map.Each software venders keep their format proprietary, so no one can turn their product into the ideal open format of web map. In recent years, SVG
(Scalable Vector Graphics), the norm of the network transmit in vector format gained the authentication from W3C. The standard inherits the open structure from XML, not only preserves the function of interactive edit like
traditional vector map, but also possess the capability of representing abundant color in map like the one in raster format. SVG rapidly becomes the appropriate file format for interactive web cartography map service.

Regarding Tainan topographic map legend as the reference, this research designs a symbol library which is compatible with SVG base shapes and PostgreSQL spatial space database. The prototype of providing adaptive visualization is developed under the system structure in Java-based language. The prototype transmits user’s browsing demand through standard communication protocol of mobile device and integrates the main results produced by the OGC WMS-compatible GeoServer. With the implementation of SVG-based symbols and adaptive visualization map
system, the prototype system provides the symbol management for map presentation and style modification. Finally, this research proceeds the full function test for the prototype using three simulation scenarios. Under setting up different parameters in user profile, the study proves the potentiality of utilizing SVG in adaptive map service for providing interactive capability.
