> Objet : [Gdal-dev] MODIS Equal Area Sinusoidal projection<br>> <br>> <br>> Hi!<br>> The MODIS HDF files for level 4 (and up) products are given<br>> using the "Equal Area Sinusoidal Projection". I have tried to
<br>> select one dataset, and export it to a GeoTIFF file using <br>> GDAL, but the projection information does not seem to <br>> work.The output GeoTIFF file does have the right metadata, <br>> thre resulting raster is not properly reprojected. I have
<br>> also tried to set the source projection with "+proj=sinu", <br>> but this does not seem to produce a good result.<br>> <br>> What I want to do is to extract one dataset from a MODIS HDF<br>> file, reproject it to UTM and then cut an area of interest.
<br>> However, without dealing with the projection issue first.<br>> <br>> Any pointers would be very appreciated!<br><br>You should try HEG Tool <a href="http://newsroom.gsfc.nasa.gov/sdptoolkit/HEG/HEGHome.html">
http://newsroom.gsfc.nasa.gov/sdptoolkit/HEG/HEGHome.html</a>.<br>This tool is made for EOS datasets including MODIS. There is a UTM option for repojection and subsetting. You can also use it in batch mode. But I do not think it uses GDAL.
