Hi,
I have some difficulties to reproject some MODIS image (Product is MOD13Q1
from earthexplorer) into a well known projection (e.g. utm).
I have tried with
1.the otbcli_Orthorectification application (which is able to reproject
too)
2.with the GenericRSResampleImageFilter
3.with gdalwarp
*(1) and (2) *lead to the same bad result i.e. large shift between original
and reprojected image (something like 20 km north) !
The input MODIS image ProjectionRef is the following:
*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]]*
*However with (3)* using gdalwarp, output image is well reprojected. (I let
gdal chose the source srs, and chose any target srs)
So, I am stuck here...
-MODIS image file format (HDF) does not seems to be a problem because I
tried on a converted GeoTiff file (same result)
-PROJ does does support sinusoidal projection ("proj -l")
-I am under OTB 4.3, internal ITK, GDAL 1.11.1 (build with PROJ 4.8.0, HDF
4)
-*One important thing*: when I reproject my MODIS image into a different
projection (e.g. lambert) with gdalwarp, and then I perform (1) or (2) on
this fresh lambert-projected-image, I get a good result. So I suspect the
problem coming from the projection ref.
Any ideas?
Rémi
