Dear all,
If have a raster which covers part of the globe (say [-180,180] longitude and [-53, 85] latitude), that I want to use in map algebra computations with other rasters that are global. For the reduced raster not to reduce the extent of the output of these computations, it seems to me that I have to replace its NoData pixels with values, as well as to extend it so it covers the whole globe.
I can reclassify the NoData (to 0 or to the global average), but I still have a reduced extent. I created a constant value raster that covers the globe and I was hoping to find a way to combine them, but I have not been very successful so far.
Could anybody tell me how to proceed (using the toolbox if possible, and not "edition by hand")?
Thank you and best regards,
Cedric
