【270】IDL处理GeoTIFF数据

参考：将原GeoTIFF数据的投影坐标信息赋值到新创建的文件上

pro tiff_projection

  ;启动ENVI

  e = ENVI(/HEADLESS)

  ;打开文件

  file = 'D:1-Working201720171204-IDL平均计算GOCI_0510GOCI_0510_01_GDPS_RC_GEO_ZJ_MASK_BIL_FLAASH_TSM.tif'

  raster = e.OpenRaster(file)

  ;读取影像的第一个波段
  data = raster.GetData(BANDS = 0)

  ;另存为新文件
  resultFile = 'D:1-Working201720171204-IDL平均计算cc.tif'
  newRaster = e.CreateRaster(resultFile, data, INHERITS_FROM = raster)
  newRaster.Save 

end
