高斯投影坐標(biāo)正反算編程報(bào)告參考模板

1、高斯投影坐標(biāo)正反算編程報(bào)告1. 編程思想進(jìn)行高斯投影坐標(biāo)正反算的編程需要牽涉到大量的公式，為了使程序條理更清楚，各塊的數(shù)據(jù)復(fù)用性更強(qiáng)，這里采取了結(jié)構(gòu)化的編程思想。程序由四大塊組成。GeodesyHomework.cpp文件用于存放main()函數(shù)，是整個(gè)程序的入口。通過(guò)結(jié)構(gòu)化的編程盡力使main()函數(shù)變得簡(jiǎn)單。MyFunction.h和MyFunction.cpp用于存放計(jì)算過(guò)程中進(jìn)行角度弧度換算時(shí)所要用到的一些自定的轉(zhuǎn)換函數(shù)。Zhengsuan.h和Zhengsuan.cpp用于存放Zhengsuan類，在Zhengsuan類中聲明了高斯投影坐標(biāo)正算所要用到的所有變量，在類的構(gòu)造函數(shù)中進(jìn)行

2、成員變量的初始化及正算計(jì)算。通過(guò)get函數(shù)獲得相應(yīng)的正算結(jié)果。Fansuan.h和Fansuan.cpp用于存放Fansuan類，類似于Zhengsuan類，F(xiàn)ansuan類中聲明了高斯投影坐標(biāo)反算所要用到的所有變量，在類的構(gòu)造函數(shù)中進(jìn)行成員變量的初始化及反算計(jì)算。通過(guò)get函數(shù)獲得相應(yīng)的反算結(jié)果。2. 計(jì)算模型 高斯投影正算公式 高斯投影反算公式 3. 程序框圖1 / 12開始輸入B，L求定帶號(hào)N，中央緯度L0，緯度差l按照實(shí)用公式計(jì)算x,y換算為國(guó)家統(tǒng)一坐標(biāo)X，Y輸出X,Y輸入國(guó)家統(tǒng)一坐標(biāo)X,Y由Y取定帶號(hào)N，并換算出x，y求出中央經(jīng)線L0按照實(shí)用公式計(jì)算B，lL=L0+l求出大地經(jīng)度L輸
