台灣因地理位置、氣候與地形等因素，孕育了豐富的森林資源。林務局廣設永久樣區以瞭解森林資源之分布與蓄積情形，永久樣區每隔五年進行全面性調查，調查所得資料繁多，惟永久樣區之植物資源調查資料僅記錄樣區之坐標位置與樣區內植物之分布情形，並未建立相關圖面資料，以至於無法與其他圖籍資料進行套疊分析。
本研究以MapServer、Zope等自由軟體與自行開發之軟體工具，處理圖形與相關屬性資料，以建構符合OGC（Open Geospatial Consortium）提出之網路地圖服務（Web Map Service，WMS）與網路圖徵服務（Web Feature Service，WFS）規格的WebGIS伺服端系統，並且整合各項森林資源表簿調查資料與圖籍資料，建構一包含森林永久樣區與樣木之空間與屬性資料的森林資源調查管理系統，以提供管理者經營管理與規劃之良好工具。 / There are plentiful forest resources in Taiwan because of the unique geographic location, climate and terrain. In order to acquire the information of distribution and storage of forest resources, the Forest Bureau sets up a lot of sample plots, and these sample plots will be fully surveyed every five years. Numerous data were collected, however only the coordinates of sample plots and the distribution of vegetation within those sample plots were recorded. It is not possible to perform map overlay analysis with the other map data because of lacking spatial data of sample plots.
In this research, a WebGIS (web-based GIS) system was developed entirely from free software including MapServer, Zope, Apache and PostgreSQL/PostGIS. This WebGIS system is based on the OGC OpenGIS architecture (WMS and WFS), therefore it is easy to share geospatial data with the other GIS systems for various applications. Furthermore, a forest resources management system was established, which integrates the attribute data from field investigation and generates spatial data of sample plots and sample trees automatically.
