先在ArcMap中將Shape file開啟,並使用buffer加到0.5M,
因切網格資料是依pixcel去切,把範加大一點比較可以將Shape file都包含

★開啟ERDAS,將Shape file開啟,並選Vector→Attribute★

★選Edit→Select All Rows→使用屬性表將Shape file全選★

★選完後就會變黃色選取狀態,並將選取區轉成AOI檔(area of interest)★

★將AOI存檔,未存檔前是存暫存區,一但關閉ERDAS資料就不存在★

★依照紅色部填寫必要資料,這一步驟就是在使用AOI去切網格資料★

★ignore Zero in output stats要選,不然就會變這樣,只剩外框0.0"★錯誤示範-.-Orz

★重新操作使用AOI去切網格資料★

★這樣就同時切出來不同區塊的DEM惹^^ ★
