For processing the large scale ( ca n ' t load in memory one time ) terrain data, there are two type technologies working through streaming, one is that data blocks are paged in on demand at full resolution first, then simplify them, the other is that data blocks are paged in at low level of detail first, then higher levels of detail is paged in incrementally. because the first technology pages more data than the second one, so researches are focused on the second technology at present
對于大規模（不能一次性進行處理的）地形的實時繪制，目前有兩流式數據處理技術：第一種流式數據處理技術是基於對數據進行分塊調度的思想，首先將地形數據分割成一定大小的塊，運行時每一個數據塊以最高的細節層次（解析度）調入，然後進行簡化；第二種流式數據處理技術是在簡化過程中進行數據的累進調度操作。
