First; I can see a band as synonymous with a channel in an image editing program like GIMP, is this correct?
If so then bands play the role of color mixing and masking. Are there any other functions of a band in GIS ie. would I ever find more than four bands in a layer?
Second; dimension applies to a raster size in the project CRS, right? This is pixel independent (the graphic card sorts it out). Change the CRS and raster dimensions change. Change resolution and the raster dimensions change.
Third; anything immediately apparent in the histogram below as to the cause of binary resolution (black hole and blank space) and what parameters to alter? Thanks so much for the help.
I just noticed from this post :
that numbers are rounded to six decimal places. This is a sample of my coordinate data:
Is it possible that I should use the raster calculator to make these numbers bigger?
