Employing raster data model for data processing and integration , and 在資料處理和集成中采用柵格資料模型;
In the raster data model , the map s accuracy also depends on the map s scale 在柵格數(shù)據(jù)模型中,地圖的準確性還依賴于地圖的比例。
Take advantage of raster - to - vector conversion , raster editing , and raster data preparation capabilities 展示集成了地圖、衛(wèi)星數(shù)據(jù)和其他形式的圖像的提案用于交流。
The library gives programmers a common data model covering all raster data formats and - through ogr - vector data formats 該庫為編程人員提供了通用的數(shù)據(jù)模型,包括所有柵格數(shù)據(jù)格式和矢量數(shù)據(jù)格式(通過ogr ) 。
However , storage might not be quite as important for raster data , whose spatial component likely contains fairly simple numerical data 然而,存儲可能不像柵格數(shù)據(jù)那樣重要,其空間構成可能包含相當簡單的數(shù)字數(shù)據(jù)。
A raster data structure is based on a (usually rectangular, square-based) tessellation of the 2D plane into cells. In the example the cells of tessellation A is overlayed on the point pattern B resulting in an array C of quadrat counts representing the number of points in each cell.
