I am working on MODIS data using GDAL. When I extract coordinate system information of the files I got this:
Coordinate System is:
PROJCS["unnamed",
GEOGCS["Unknown datum based upon the custom spheroid",
DATUM["Not specified (based on custom spheroid)",
SPHEROID["Custom spheroid",6371007.181,0]],
PRIMEM["Greenwich",0],
UNIT["degree",0.0174532925199433]],
PROJECTION["Sinusoidal"],
PARAMETER["longitude_of_center",0],
PARAMETER["false_easting",0],
PARAMETER["false_northing",0],
UNIT["Meter",1]]
Origin = (2223901.039533000000000,0.000000000000000)
Pixel Size = (926.625433139166600,-926.625433139166720)
I have to transform the coordinate system of my other files into this coordinate system. But the problem is that I don't know how to introduce this coordinate system to my program. I can't find EPSG or Proj4 for it. Any solution or alternative?
