I am using FWtools for pre processing of time-series MODIS data, I want to mosaic series of two scenes. But I don't know the batch code for gdalwarp.
I am using windows.
Kindly help me out.
It is not completely clear to me what you are trying to do, but if you simply want to mosaic two images using gdalwarp, this should work:
If your data is in one of the FAST formats, GDAL can handle the conversion too.
if you want to mosaic two tiles, you can use gdalwarp. Another option is to build a VRT (virtual dataset) that does the temporal stacking AND the mosaicking. You can either convert the resulting VRT to say a GeoTIFF, or if you are using GDAL-aware tools, use it as a normal raster dataset.
I have a blog entry that describes how to do just that in great detail.
