Raster Size Concepts Explained – How big is my raster?
When you convert a raster to MRR format, and then convert the MRR back to a raster in the original format, the size of the raster almost always changes. Why is this and what is going on behind the scenes? In this article I explain some of the concepts around raster size in an MRR format raster, exploring concepts like Grid Size, Cell Range, Valid Cell Range and Extant Tile Boundary. I also explore the issues around the file size of an MRR format raster, and what properties affect file size.
