hi friends ;-),
just wanted to ask for any practical hints (algorithms) on downsampling
very large raw binary (32 bit integer) raster file from disk. Looking
for an algorithm or library that could be implemented or used in Ada,
C/C++, Fortran, Assembly, Perl, Python or whatever else. The simpler the
better :-). My aim is to subsample 2-4 gigabyte raster data file without
loading it into RAM within 10 seconds on an "ordinary" PC with Intel
processor (Windows, Linux, MacOSX on Intel). Wishing to explore as many
options as possible... If you know any paper or website dealing with
this kind of algorithms, I would appreciate the url.
For example I have 50000x50000 raster and I need a portion of it resized
to 700x700...
Thanks in advance
All the best!
Viktoras
