#################################### 生成经纬度文件 ##############################

建立经纬度文件

(1)生成pointlist

mkgrid plist 5800 2000 1 1 1 1

(2)将栅格转为点格式

data2pt cop30.rdc.hgt 20231227.rmli.par plist 20231227.rmli.par pdem 1 2
# cop30.rdc.hgt 雷达坐标系下的dem

(3)生成经纬度数据

pt2geo plist - 20231227.rmli.par - pdem cop30.utm.par diff_par.in 1 1 plist_map pmap_coord plat_lon phgt 0 pmask_dem
# cop30.utm.par utm 坐标系下dem的par文件

(4)swap

swap_bytes plat_lon plat_lon4 4

(5)python拆分

python3 lonlat.py

‘’’

import numpy as npcors = np.fromfile('plat_lon4', np.float32)lon = cors[0:len(cors):2]
lat = cors[1:len(cors):2]lon.tofile('lon.raw')
lat.tofile('lat.raw')

‘’‘’

(6)swap

swap_bytes lon.raw lon4.raw 4
swap_bytes lat.raw lat4.raw 4
