Dear GDAL and Proj Developers and Users: I am really frustrated when the MODIS HDF file converted into GeoTiff with GCS projection never match with the same MODIS file converted from MODIS Reprojection tool.
The file I am working is here: http://e4ftl01.cr.usgs.gov/MOTA/MCD43A4.005/2015.01.01/MCD43A4.A2015001.h26v05.005.2015027224017.hdf I used the following parameters for gdalwarp: -t_srs wgs84 -tr 0.004166666666667 0.004166666666667 I used the following parameters for MRT: OUTPUT_PIXEL_SIZE = 0.004166666666667 DATUM = WGS84 OUTPUT_PROJECTION_TYPE = GEO The image produced from MRT has: size = 6025*2400 point-based ulx, uly = 92.3799071, 40.0000000 The image produced from gdalwarp has: size = 6027*2400 area based ulx, uly = 92.3760431, 40.0000000 Do you have any idea on which is more precise: gdalwarp or MRT? Or there is any way in gdalwarp to get the same image as MRT gives? Any idea and experience is highly appreciated. Thank you very much in the advance! Sincerely yours, yuta sato
