For example, if we have the global climate data (in the h5 format) from MODIS (sinusoidal projection) with some resolution (say, 250m or 1km) and we'd like to construct 50km x 50km resolution for only the states of USA, excluding Hawaii and Alaska. <br><font face="Tahoma" color="black" size="2"><span dir="ltr" style="font-size:10pt"></span></font><br>
<font size="2"><span style="font-size:10pt">I think it may require the
center coordinates of each 50km pixel, as well as the upper left and
lower right coordinates of each. Also, for each pixel, it might be
useful to have which US States the pixel crosses. </span></font><font size="2"><span style="font-size:10pt"><font size="2"><span style="font-size:10pt">It may also require some shape files to extract data for only US.
