I'm analyzing level-3 Modis products, for example: http://e4ftl01.cr.usgs.gov//MODIS_Composites/MOTA/MCD43A4.005/2011.08.21/MCD43A4.A2011233.h12v04.005.2011250155139.hdf

When I finish my analysis I have a 2400X2400 matrix that I want to plot, but since the original image was in sinusoidal projection, when I use imagesc it plots the image in a distorted way. I want to convert the image to geographic coordinates before plotting it. How can this be done?

Hi,

I am exactly meeting the same problem. I wonder if you have figured out this problem yet?

Thanks

Hi, I extracted the pixel lat-lon coordinates using this: https://www.mathworks.com/matlabcentral/fileexchange/37033-find-pixel-indices-in-hdf-eos-files-based-on-latlon-coordinates

and then used surfm to plot.
