I am using following matlab line to get map_info and coord_sys_str
% Construct the 'map info' string
map_info = sprintf('{%s, 1, 1, %.10f, %.10f, %.10f, %.10f, %s}', ...
R.ProjectedCRS.Name, x0, y0, x_pixel_size, y_pixel_size, units);
% Get the coordinate system string
% methods(R.ProjectedCRS);
coord_sys_str = R.ProjectedCRS.wktstring;
the output is as follows
map info = {WGS 84 / UTM zone 43N, 1, 1, 376944.5785894837, 2068390.0758226500, 10.0000000000, 10.0000000000, meter}
coordinate system string = {{PROJCRS["WGS 84 / UTM zone 43N",BASEGEOGCRS["WGS 84",DATUM["World Geodetic System 1984",ELLIPSOID["WGS 84",6378137,298.257223563,LENGTHUNIT["metre",1]],ID["EPSG",6326]],PRIMEM["Greenwich",0,ANGLEUNIT["degree",0.0174532925199433],ID["EPSG",8901]]],CONVERSION["UTM zone 43N",METHOD["Transverse Mercator",ID["EPSG",9807]],PARAMETER["Longitude of natural origin",75,ANGLEUNIT["degree",0.0174532925199433],ID["EPSG",8802]],PARAMETER["Latitude of natural origin",0,ANGLEUNIT["degree",0.0174532925199433],ID["EPSG",8801]],PARAMETER["Scale factor at natural origin",0.9996,SCALEUNIT["unity",1],ID["EPSG",8805]],PARAMETER["False easting",500000,LENGTHUNIT["m",1],ID["EPSG",8806]],PARAMETER["False northing",0,LENGTHUNIT["m",1],ID["EPSG",8807]],ID["EPSG",16043]],CS[Cartesian,2],AXIS["easting",east,ORDER[1],LENGTHUNIT["Meter",1]],AXIS["northing",north,ORDER[2],LENGTHUNIT["Meter",1]]]}}
When I open this file in ENVI it is not showing lat/lon.
if I copy the georeferenced information from my input header file to output header file which is as follows then it shows the lat/lon on screen in ENVI.
map info = {UTM,14186.0,10802.5,434499.57858948375,2004780.07582265,10.0,10.0,43,North,World Geodetic System 1984,units=Meters}
coordinate system string = {PROJCS["WGS 84 / UTM zone 43N", GEOGCS["WGS 84", DATUM["World Geodetic System 1984", SPHEROID["WGS 84", 6378137.0, 298.257223563, AUTHORITY["EPSG","7030"]], AUTHORITY["EPSG","6326"]], PRIMEM["Greenwich", 0.0, AUTHORITY["EPSG","8901"]], UNIT["degree", 0.017453292519943295], AXIS["Geodetic longitude", EAST], AXIS["Geodetic latitude", NORTH], AUTHORITY["EPSG","4326"]], PROJECTION["Transverse_Mercator", AUTHORITY["EPSG","9807"]], PARAMETER["central_meridian", 75.0], PARAMETER["latitude_of_origin", 0.0], PARAMETER["scale_factor", 0.9996], PARAMETER["false_easting", 500000.0], PARAMETER["false_northing", 0.0], UNIT["m", 1.0], AXIS["Easting", EAST], AXIS["Northing", NORTH], AUTHORITY["EPSG","32643"]]}
Please suggest me how to get these georeferenced information correctly.
