Technical term is generalization. Pretty much every GIS or cartography book ever written has a chapter dedicated to it. For example:  https://www.geos.ed.ac.uk/~gisteac/gis_book_abridged/files/ch10.pdf And yes, it is valid.

I have 225x225 raster data, if I increase the pixel size to 100x100 or 30x30 is it valid in a scientific method? Is there a reference source that I can refer to in this regard?
