  1. Qgis handles all three - raster, vector, and database - a state of affairs that took considerable effort for programmers writing gis data programming libraries

    Qgis處理所有三種數據柵格數據、矢量數據和數據庫，這也是編寫gis數據編程庫的程序員的重要努力方向。
  2. ( 3 ) the function of spatial analysis of gis is made full use of. the fundamental methods and work process with the analysis function of spatial overlap of raster data to have a hazard assessment of landslide are found out

    （ 3 ）在研究中充分利用了地理信息系統的空間分析功能，摸索出了利用柵格數據的空間疊加分析功能，進行滑坡危險性評價的基本方法和工作流程。
  3. This paper supplies systematic research on data organization method which is suitable for hngis, at the same time studies deeply on the optimization of transit route with many goals in highway network. ( 1 ) based on the systematic analysis on the spatial data model and the spatial data structure, through study on two kinds of commonly used gis data models : raster data model, vector data model and the characteristics of highway network, the paper plans the logistic data model of hngis, and proposed the spatial data storing structure based on vector method

    本文系統的研究了適合於公路網gis的數據組織方法，同時，對公路網多目標最優出行路徑問題也給予了深入的研究： （ 1 ）通過對兩種常用的gis數據模型（矢量數據模型、柵格數據模型）及對公路網路特徵的分析，設計了公路網gis的邏輯數據模型，給出了基於矢量方法的空間數據存儲結構。
  4. The distribution gis data management methods and its application in distribution running are systematically researched, which compose distribution gis network topology analysis ( nta ) and optimal rush - maintain path ( orp ), and distribution planning, which composes distribution spatial load forecasting ( slf ) : ( 1 ) with systematic analysis on the relationship between spatial data model and spatial data structure, the distribution feature and the two common gis data models are analyzed, which are vector and raster data models. then the conceptual and logic data models of distribution gis are designed. the spatial data storage structure is given by using vector method, and their detailed data management methods are proposed

    （ 4 ）將gis的空間信息分析功能應用於配網空間負荷預測（ saptialloadforecasting ， slf ）的研究：綜合利用灰色理論及遺傳規劃的優點，提出了一種根據饋線的歷史峰值負荷進行外推的組合slf法：首先採用負荷轉移耦合法來修正負荷歷史，消除由於負荷轉移引起的誤差；然後根據實際饋線路徑和配網gis圖形分層，運用圖層疊加分析得到饋線的實際供電范圍；接著採用灰色關聯度聚類方法對饋線負荷增長曲線進行聚類分析；最後採用遺傳規劃來對灰色聚類結果進行符號回歸，分別得到每一類曲線的最佳擬合曲線形式。
  5. Tagged image file format. tiff is another commonly used raster - based image format, which gis specialists adapted to geographers needs and renamed geotiff

    帶標記的圖像文件格式（ . tiff ）是另一種常用的基於柵格的圖像格式， gis專家為適應地理學者的需要將其重命名為geotiff 。
  6. The integrated information units could be identified by a variety of methods according to different data types and issues including overlay - operation for vector gis, cell - partition for raster gis, and for some cases, synthetical consideration based on special treatment or expert - knowledge

    針對不同的相關因子以及數據類型，綜合信息元可以採用數據疊加法、綜合法和網格劃分法等進行構建。
