時空資料庫之研究 以土地使用分區變遷為例

Abstract

人類都在一定的空間和時間環境中生存並從事各種社會活動，因此在現實生活中，所有的活動與現象都是隨著時間不斷的改變，空間和時間是不可分割地聯繫在一起。然而，傳統的地理資訊系統應用只涉及空間資料和屬性資料兩方面的地理資訊，如何將傳統GIS應用與時間因數整合，即為時空(Spatio-temporal)地理資訊系統的研究重點。 土地使用分區常隨著人類活動的演變與環境的變遷來進行適當的調整，故土地使用為都市與區域規劃最主要的內容之一。當我們要瞭解土地使用分區在時間上的變化過程時，就必須藉助時空地理資訊系統來管理與記錄空間、屬性和時間資訊。 本研究透過地理資訊系統與關聯式資料庫結合，嘗試從土地使用分區資料特性著手，利用物件導向概念，加入時間因素的考量，作為都市計畫土地使用分區的管理機制，期望藉由土地使用分區變遷的追蹤與管理，驗證其結合時空資料庫之可行性。

Humans are living and engage in social activities around the certain space and time. Therefore, all kinds of activities and phenomena in reality are changed through time. Space and time is indivisibility indeed. However, traditional GIS applications just touch on spatial and attribute data regardless of time factor. How to integrate traditional GIS applications with time is the important issue on spatio-temporal GIS. Land-use zoning needs to be adjusted appropriately according to evolution of humans’ activities and changes of environment. So it is the major subject of urban and region planning. When we want to understand the process of land-use zoning change through time, we need to use spatio-temporal GIS system to manage and record spatial, attribute and time information. In this case, I try to use the character of land-use zoning data, object-oriented concept and time factor to implement the management system of land-use zoning of urban planning by integrating GIS system with relational database management system (RDBMS) and expect to proof that the spatio-temporal database is workable in trace and management of land-use zoning change.
