raster map 解釋
柵格地圖
  • raster : n. 【電視】光柵，（無圖像的橫線）屏面；【攝影】綱板。
  • map : MAP ＝Military Aid Program 〈美國〉軍事援助計劃。n 1 地圖；天體圖；圖。2 〈美俚〉臉，面孔。3 〈美...
  1. First, the basic principles of geometry rectification of digital aerial images and raster relief map are introduced and thus the accuracy of geometry rectification is improved

    首先，重點闡述了數字航空影像幾何糾正，以及柵格地圖變形糾正的基本原理，進一步提高了幾何糾正的精度。
  2. A method erasing noises on raster map based on extension character

    基於外延特徵的柵格地圖噪聲去除演算法
  3. There are two kinds of data form for map data, one is in the raster form, the other is the vector one

    地圖數據的存儲形式一般有兩種：柵格數據和矢量數據。
  4. In the raster data model, the map s accuracy also depends on the map s scale

    在柵格數據模型中，地圖的準確性還依賴于地圖的比例。
  5. Vector data require far less storage than raster data because arc node lists simplify and reduce the data required to make sense of the features contained in the map

    矢量數據要求的存儲要比柵格數據少得多，因為弧節點列表簡化並減少了表示地圖中包含的特徵所需的數據。
  6. U sers can always reference raster images as an underlay of their drawings ( e. g., satellite images, aerial photos ), for instance, for the street map underlay

    影像檔案可以很大，尤其是當影像檔案詳細地覆蓋廣闊的面積時。為使影像檔案更易於處理，經常將影像分解為覆蓋較小面積的地圖框。
  7. Integrating raster with vector methods of updating the basic land - use map based on 3s technology is becoming one of the most important developing direction in 3s application field ; land - use and cover change field over the world

    利用3s技術進行土地利用基礎圖件更新已成為國內外3s應用領域和土地利用與覆被變化領域（ lucc ）一個興起的研究方向。
  8. The algorithm takes advantage of the merits of the watermarks both in low frequency and high frequency and can embed more information with less distortion. experimental results show the algorithm is robust to many common image operations. as for the vector map data, an uniform model of embeding watermark for vector maps and raster maps is proposed after current trend of research and watermarking methods of 3 - d vector images are summarized, primary study results show the model is effective and promising to further research

    目前該問題在國內外都還處于探索階段，作者在分析了國內外三維矢量水印的研究狀況、研究方法后，提出了將矢量數據中的部分信息轉化為柵格形式后再嵌入水印的方法，該方法使地圖柵格數據和矢量數據在嵌入水印時能夠使用統一模型，初步的實驗結果表明該方法為二維地圖矢量數據的水印嵌入開辟了一種新途徑。
  9. Raster topographic map application system based on mapinfo : development and realization

    與全站儀聯合應用實踐與分析
