This is about ENU files Reading and plotting
wdir=r'C:\Users\OHanlon\Desktop\plotData\xyz\enu'
pdir=r'C:\Users\OHanlon\Desktop\plotData\xyz\enu\png'
sitelist=['ABMF','ABPO']
time='2022049'
sys='GEC'
freq='2'
comb='IF'
ambfix='AR'
len = 350
lgds = ['Float','2-Fixed','3-Fixed']
for site in sitelist:
f1=wdir+'\\'+ site + '_'+time +'_'+ sys+'_2_IF_F.enu'
f2=wdir+'\\'+ site + '_'+time +'_'+ sys+'_2_IF_AR.enu'
f3=wdir+'\\'+ site + '_'+time +'_'+ sys+'_3_IF_AR.enu'
data1=gr.read_enu(f1)
data2=gr.read_enu(f2)
data3=gr.read_enu(f3)
Data = np.array([data1[0:len,:],data2[0:len,:],data3[0:len,:]])
tmp=data1[0:len,:]
print(gm.get_ConTime(tmp))
gd.draw_enu(Data,lgds,site)
path=pdir+'\\'+site+'.jpg'
plt.savefig(path, dpi=300)这部分需要的函数在 func/coordinate.py 文件中，使用前需要导入
import sys
sys.path.append(os.path.abspath(os.path.join(os.path.dirname(__file__), '..')))
from funcs import coordinate as fcd地心地固三维空间直角坐标系坐标 → 大地坐标系坐标
xyz0=[4097216.5161,4429119.2396,-2065771.1467]
x0=xyz0[0];y0=xyz0[1];z0=xyz0[2]
ell0=fcd.cart2ell(x0,y0,z0)
print(ell0)
b0=ell0[0];l0=ell0[1];h0=ell0[2]地心地固三维空间直角坐标系坐标 → 站心坐标系坐标 在进行这个转换的时候需要知道站心的三维空间直角坐标或者大地坐标，下面是已知空间直角坐标xyz0为例进行转换的
xyz0=[4097216.5161,4429119.2396,-2065771.1467]
xyz1=[4097216.4745,4429119.2696,-2065771.1622]
dx=xyz1[0]-xyz0[0];dy=xyz1[1]-xyz0[1];dz=xyz1[2]-xyz0[2]
x0=xyz0[0];y0=xyz0[1];z0=xyz0[2]
ell0=fcd.cart2ell(x0,y0,z0)
enu1=fcd.dxyz2enu(ell0,[dx,dy,dz]) # 方法一，by jqwu
print(enu1)方法二
xyz0=[4097216.5161,4429119.2396,-2065771.1467]
xyz1=[4097216.4745,4429119.2696,-2065771.1622]
dx=xyz1[0]-xyz0[0];dy=xyz1[1]-xyz0[1];dz=xyz1[2]-xyz0[2]
x0=xyz0[0];y0=xyz0[1];z0=xyz0[2]
ell0=fcd.cart2ell(x0,y0,z0)
b0=ell0[0];l0=ell0[1];h0=ell0[2]
rotm=fcd.ell2topo(b0,l0,h0)
dxyz=np.matrix([dx,dy,dz])
print(dxyz*rotm[0],dxyz*rotm[1],dxyz*rotm[2])这两种方法都是得到 ENU，注意，这里顺序可是没有错噢。第一种方法更为简单；当进行很多个坐标转换的时候，也许第二种方法的效率更高一些。
