【摘要】：為了滿足對任意幾何區(qū)域進(jìn)行覆蓋特性分析的需要,在傳統(tǒng)網(wǎng)格點覆蓋法對矩形區(qū)域進(jìn)行覆蓋特性分析的基礎(chǔ)上,對網(wǎng)格點構(gòu)建、衛(wèi)星過境覆蓋分析等環(huán)節(jié)進(jìn)行改進(jìn),使其適合對任意幾何區(qū)域進(jìn)行覆蓋特性分析的需要,最后以中國行政區(qū)域為例進(jìn)行實驗并通過過境特性表、過境重繪圖和覆蓋重數(shù)圖等進(jìn)行覆蓋特性的可視化。結(jié)果表明了對地覆蓋法在任意幾何區(qū)域上能夠準(zhǔn)確地計算出其每次過境的覆蓋區(qū)域及總覆蓋區(qū)域,同時在實驗分析中通過多種可視化方法展示目標(biāo)區(qū)域的覆蓋特性,使其更加直觀。
[Abstract]:In order to meet the need of analyzing the coverage characteristics of arbitrary geometric regions, based on the analysis of the coverage characteristics of rectangular regions by the traditional grid point coverage method, the construction of grid points and the analysis of satellite transit coverage are improved. It is suitable for the analysis of the coverage characteristics of any geometric region. Finally, taking the administrative region of China as an example, the overlay characteristics are visualized through the transit characteristic table, the transit redrawing and the overlay multiplicity chart. The results show that the ground cover method can accurately calculate the coverage area and the total coverage area of each transit in any geometric region. At the same time, the coverage characteristics of the target area are displayed by various visual methods in the experimental analysis. Make it more intuitive.
