- 實(shí)驗結果表明,所建立的柵格DEM表面高程誤差隨著(zhù)TIN的轉換閾值的增大而增大、所提取的地面坡度、溝壑密度的精度隨之降低。The experiment shows that the conversion accuracy between Grid DEMs and TINs affected by conversion tolerance of TINs directly.
- 本文在總結前人關(guān)于地形信息問(wèn)題研究成果的基礎上,提出了柵格DEM數據的地形信息容量的概念,并以陜北黃土高原為實(shí)驗樣區,探討有關(guān)DEM數據地形信息容量的問(wèn)題。Based on the summaries of former researches on topographic information and DEMs of Loess Plateau in North Shaanxi, This thesis comp up with a new concept, Terrain Information Parameters (TIPs) of DEMs, and explain the relations between TIPs and real landform.
- 柵格DEM與TIN是DEM表面建模主要的2種方法。 應用DEM進(jìn)行地形分析時(shí),柵格DEM與TIN的相互轉換非常必要,但在轉換中所產(chǎn)生的誤差直接或間接地影響到分析結果的準確性。The conversion between Grid DEMs and TINs is of critical significance in digital terrain analysis which is a key work in the watershed planning of the loess plateau region.
